• Participants will identify:– Dates for New ICD-10– Documentation support– New terms encounter principal diagnosis re-
defined– Some general coding guidelines
Objectives
3
• January 15, 2009 Final Regulation Released
• EXCHANGE the ICD-9 for the ICD-10 on October, 1, 2014
Final Regulation
4
• ICD-10 CM = Clinical Modification, ICD-10 CM – applies to SNF, Intermediate Care, Physician’s Offices, Clinics, Dialysis, Home Health, other health care settings who bill Medicare, MediCal or Private Ins.
• ICD-10 PCS = Procedural Code System (used for Acute Hospital procedures, operations
ICD-10 “Has Two Parts”
5
• Assigning ICD-10 diagnosis codes is required under the Health Insurance Portability and Accountability Act (HIPAA)
• HIPAA has evolved from 1996 to HITECH which relates to security and breaches
• HIPAA Transactions 5010 went into effect October 2011
• HITECH – HIPAA Privacy and Security final rule was released January 2013
HIPAA
6
• All inpatient and outpatient facility visits as well as freestanding providers and ancillary services “that means all of us really” who provide services and bill for them under Medicare, Medi-Cal and private insurances.
Who Is Affected??
7
• More specific coding system• Reflects medical advancements• Standardization, UK implemented in 1995,
used worldwide• The United States is the only industrialized
nation that has not yet implemented ICD-10
Benefits
8
• The guidelines in the ICD-10 manual developed for the provider and the coder….(person who may review the documentation and determine if code is accurate.
• Consistent, complete documentation in the medical record is a major emphasis.
What Does This Mean??
9
• ICD-10 CM replaces ICD-9 CM diagnosis codes in all settings
• ICD-10 PCS (Procedural Code System)• – replaces ICD-9 CM in the inpatient• hospital setting• Current Procedural Terminology (CPT) is
still used for the Physician, and some services, but they must have a diagnosis that is ICD-10 compliant
Key Highlights
10
• Healthcare Common Procedural Coding system (HCPCS Level II) remains the same for outpatient reporting for procedures and services.
• ICD-10 CM/PCS – Increased level of detail required for medicine advancements in technology, $$, improved data quality for clinical and financial decision making, to support value based purchasing and facilitate quality reporting.
Key Highlights -2
11
• 3-5 characters in length• Approximately 14,000 codes• First digit may be alpha or numeric• Digits 2-5 are numeric• Always at least three digits• Decimal placed after the first three
characters• Limited space for new codes
ICD-9-CM Diagnosis Codes
12
• Lacks detail• Lacks laterality, difficult to analyze, dated,
non-specific and does not adequately define diagnoses needed for medical research
• Does not support interoperability because it is not used in other countries.
ICD-9-CM Diagnosis Codes -2
13
• Index and Tabular list have the same hierarchical structure as ICD-9
• ICD-10 index larger, categories, subcategories and codes are contacted in the tabular list.
ICD-10 CM Structure
14
• ICD-9 V and E code supplemental classifications are incorporated into the main classification in ICD-10
• ICD-9 V codes are now Z codes and in Chapter 21. Factors Influencing Health Status and Contact with Health Services
• Postoperative complications have been moved to procedure-specific body system chapters
ICD-10 CM Structure -2
15
• 3-7 characters in length and alphanumeric• 21 chapters (compared to 17 in ICD-9)• Approximately 68,000 codes• Digit 1 is always alpha, digit 2 is numeric;
digits 3-7 can be alpha or numeric• Decimal placed after the first 3 characters
ICD-10-CM Diagnosis Codes – Format & Structure
16
• Codes that have applicable 7th character is considered invalid without the 7th character.
• Expanded codes• Flexible for adding new codes• Addition of placeholder “X”• Has laterality (rt. Left, lower, upper, outer,
etc.)
ICD-10-CM Diagnosis Codes – Format & Structure
• ICD-10 utilizes a placeholder character “x”• The “x” is used as a placeholder at certain
codes to allow for expansion– See categories T36-T50, poisoning codes
T36.8X1– Also, Pathological vertebral fracture due to
age-related osteoporosis, subsequent encounter with delayed healing M80.08XG
Example Of Placeholder “X”
18
• For bilateral sites, the final character of the codes in ICD-10 indicates laterality.– C50.212 Malignant Neoplasm of upper-inner
quadrant of left female breast– H02.835 Dermatochalasis of left lower eyelid– I80.01 Phlebitis and Thrombophlebitis of
superficial vessels of right lower extremity– L89.213 Pressure Ulcer of right hip, Stage 3– An unspecified site code is also provided
should the site not be identified.
Example Of Laterality
19
• Expanded Codes (injury, diabetes, alcohol/substance abuse, postoperative complications)
• E08.22 Diabetes mellitus due to underlying condition with diabetic chronic kidney disease
Example Of Expanded Codes
20
• Diabetic Mellitus – • w/arthropathy NEC#11.618 (Type 2
diabetes with other diabetic arthropathy)• w/cataract E11.36 (Type 2 with diabetic
cataract)• w/gangrene E11.52 (Type 2 with diabetic
peripheral angiopathy w/gangrene)
Diabetes
• w/foot ulcer E11.621 (type 2 diabetes with foot ulcer
• (use additional code to identify site)
Diabetes #2
• w/hypoglycemia E11.65• w/kidney complications E11.29
Diabetic #3
• Requires “use” of proper coding guidelines– Relies on the use of the guidelines and in our
case Skilled/ICF rules (more on this subject later during full training)
– ICD-10 CM Index – disease and injury and external causes of Injury
ICD-10 CM Structure -
24
– More combined codes, i.e. Diabetic retinopathy is one code
– More specificity, i.e. Alzheimer’s disease with specific details of early or late onset
– G-30.9 et’l’– G30.0 Alzheimer’s with early onset– G30.1 “ with late onset– G30.9 Other Alzheimer’s
ICD-10 CM Structure
• Alzheimers…you may need to use with behavioral disturbance and without behavioral disturbance.
• >>key to psychoactive Drugs!!• ???behavioral disturbance ???justification
for psychotrophics ????
ICD-10 CM Structure
• General rules for use of the classification independent of the guidelines– Alphabetic Index and Tabular List
• Alphabetic Index – List of terms and their corresponding code
• Tabular List – chronological list of codes divided into chapters based on body system/condition
• General coding guidelines are similar to ICD-9 with one additional guideline - laterality
Conventions For The ICD-10-CM
27
• General rules for use of the classification independent of the guidelines– Format and Structure
• First character is always alpha• Three character category that has no further
subdivision is equivalent to a code• Subcategories are either 4 or 5 characters• Codes may be 3, 4, 5, 6 or 7 characters
Conventions For The ICD-10-CM -2
28
• General rules for use of the classification independent of the guidelines– 7th Characters
• Certain ICD-10-CM categories have applicable 7th characters
• Required for all codes within the category or as instructed by the notes in the Tabular List
• Must always be the 7th character in the data field• If a code that requires a7th character is not 6
characters, a placeholder X must be used to fill in the empty characters
Conventions For TheICD-10-CM -3
29
• Seventh character for a fracture– A = initial encounter for fracture– D = subsequent encounter for fracture with
routine healing– G = subsequent encounter for fracture with
delayed healing
Examples Of 7th Character
30
– K = subsequent encounter for fracture with nonunion
– P = subsequent encounter for fracture with mal-union
– S = sequela
Examples of 7th Character
• Fracture Traumatic (abduction, adduction, separation)
• Acetabulum – anterior, displaced, illopubic S32.43 or non-displaced S32.436
• Acetablum – dome (displaced) S32.48• Fracture, lumbar vertebrae - (NOS• .
FRACTURE
• Fracture of lst lumbar vertebrae – S32.01, wedge compression, stable burse, unestablish, other, unspecified
FRACTURE
• Specificity improves coding accuracy and depth of data for analysis
• Detail improves the accuracy of data used in medical research
• Supports interoperability and the exchange of health care data between other countries and the U.S.
ICD-10-CM Diagnosis Codes -4
34
• ICD-10 Code Format
Code Format
35
ICD-9-CM Code Format ICD-10-CM Code Format
• Before we go further- do not despair…your vendor should prepare as much crosswalk as possible. There are “GEM” files.
• General Equivalence Mappings (GEM) – translation dictionary for diagnoses
• !!
GEM Files
36
• There is NOT a one-to-one match between ICD-9 and ICD-10 codes
• We will talk about GEMS later and how to use them. Key to early review!
GEM FILES
• Identify your most common diagnoses.• Determine in advance some of the
documentation issues that you will have with the nurses and the physicians
• Discuss the specificity at the QA/PI meetings
• Keep staff informed as we progress
\WHAT DOES THAT MEAN TO ME?
• The organization will need to know for all facilities or your facility what the most common diagnoses that are admitted and focus on those first
• Focus on the documentation to support those
• Focus on review of Acute Hospital Records more closely – Impact Inquiries
WHAT DOES THIS MEAN TO ME?
• Review for Medicare must be more specific
WHAT DOES THIS MEAN TO ME?
• Organization• Structure• Code composition• Level of detail• May consist of 3 to 7 digits, with the
seventh digit extensions representing visit encounter or sequel, as stated above.
ICD-10 & ICD-9 Differences
41
• Includes full code titles for all codes (no reference back to common 4th and 5th digits)
• V and E codes are no longer supplemental classifications, as stated previously
ICD-10 & ICD-9 Differences -2
42
• NEC – Not Elsewhere Classified for conditions not classified elsewhere
• NOS – Not Otherwise Specified if condition is insufficient to assign more specific code
Abbreviations & Punctuation
43
• Punctuation– [ ] Brackets (synonyms, alt wordings,
explanatory phrases)– ( ) Parentheses (nonessential modifiers/
supplementary words)– : Colon (used with includes and excludes
notes)
Abbreviations & Punctuation #2
• Inclusion notes further define, or give examples of the content of the category
• Exclusion notes – Excludes1 vs. Excludes2– Excludes1 means “not coded here”– Excludes2 means “not included here” may
need to use both the code and the excluded code together if patient has both conditions
• Code first and Use additional code notes are similar to ICD-9
Instructional Notes
45
• Cross Reference Notes advise coder to look elsewhere before assigning code (see, see also, see condition)
• And = and/or• With = associated with or due to• Code also note instructs that two codes
may be required – does NOT pertain to sequencing
Instructional Notes -2
46
• Etiology/manifestation - “Code first”, “use additional code” and “in diseases classified elsewhere” notes– Requires that the underlying condition be
sequenced 1st, followed by the manifestation– Provides assistance with proper sequencing
order of the codes– Level of detail in coding– -must use and report the highest
number of characters available
Instructional Notes -3
47
• Locating a code in the ICD-10-CM• Level of detail coding• Code/codes from A00.0 through T88.9,
Z00-Z99.8• Signs and symptoms are acceptable for
reporting purposes when a related diagnosis has not been established
General Coding Guidelines
48
• Signs and symptoms that are associated routinely with a disease process should not be assigned as additional codes
CODING GENERAL GUIDELINES #2
• Acute and Chronic Conditions– If the same condition is described as both
acute and chronic, and separate subentries exist, code both and sequence the acute code 1st
• Combination Code– Is a single code used to classify two
diagnoses, or– A diagnosis with an associated complication
or manifestation
General Coding Guidelines -2
50
• Late Effects (Sequela)– Residual effect (condition produced) after the
acute phase of an illness/injury has terminated
– There is no time limit on when a sequela code can be used
– Coding generally requires two codes– Condition/nature of the late effect is
sequenced 1st; the sequela code is sequenced 2nd
General Coding Guidelines -3
51
• Late Effects (Sequela)– Exception is when the sequela code is part of
the 4th, 5th or 6th character of a code – The code for the acute phase of an illness or
injury that led to the sequela is never used with a code for the late effect
General Coding Guidelines -4
52
• Documentation for BMI and Pressure Ulcer Stages– Assignment may be based on medical record
documentation from clinicians who are not the patient’s provider
General Coding Guidelines -5
53
– Dietitian often documents the BMI and nurse often documents the pressure ulcer stages
– The associated diagnosis must be documented by the patient’s provider
– BMI codes should only be reported as secondary diagnoses
GENERAL CODING GUIDELINES
• Code assignment is based on the provider’s documentation
• Not all conditions that occur during or following surgery are classified as complications
Complications Of Care
55
• When admission is for treatment of a complication, the complication code is sequenced as the principal diagnosis
• Must be a cause-and-effect relationship between the care provided and the condition and an indication in the documentation that it is a complication
COMPLICATIONS OF CARE
• Uniform Hospital Discharge Data Set (UHDDS)/Principal diagnosis is defined as that condition established, after study, to be the chief cause of the admission of the patient to the facility for care
• Condition must be identified in the H&P or documented in the current inpatient medical record
OSHPD / Principal Diagnosis Definition
57
• What that means to a SNF– Acute hospital diagnosis– Late effects– Reason for the admission to Acute and the
SNF (bundled payments) – one facility gets paid and the other is paid by that facility.
ACUTE HOSPITAL – PRINCIPAL DX
• Two or more interrelated conditions with each potentially meeting the definition– Such as diseases in the same ICD-10-CM or
manifestations characteristically associated with a certain disease potentially meeting the definition of principal diagnosis, either condition may be sequenced first, unless the circumstances of the admission, the therapy provided, the Tabular List, or the Alphabetic Index indicate otherwise
Principal Diagnosis
59
• Two or more interrelated conditions that equally meet the definition– When two or more diagnoses equally meet
the criteria for principal diagnosis as determined by the circumstances of admission, diagnostic workup and/or therapy provided, and the code book does NOT provide sequencing direction, any one of the diagnoses may be sequenced first
Principal Diagnosis -2
60
• Two or more comparative or contrasting conditions– When two or more diagnoses are documented
as “either/or”, they are coded as if the diagnoses were confirmed and the diagnoses are sequenced according to the circumstances of the admission.
– Either diagnosis may be sequenced first.
Other Diagnoses
61
– When a symptom is followed by contrasting/comparative diagnoses, the symptom code is sequenced first.
– These should never be principal diagnoses
OTHER DIAGNOSES
• Codes for symptoms, signs, and ill-defined conditions – are NOT to be used as a principal diagnosis when a definitive diagnosis has been established.
• THIS APPLIES TO SNF, ACUTE and other health locations
Signs, Symptoms, Ill-defined Conditions
63
• Uncertain Diagnosis– If the diagnosis documented at the time of
discharge is qualified as “probable”, “suspected”, “likely”, “questionable”, “possible”, or “still to be ruled out”, or other similar terms indicating uncertainty, code the condition as if it existed/established
– Applicable only to inpatient admissions to short-term, acute, long-term care & psychiatric hospitals
Uncertain Diagnoses
64
• Determined by the reason for admission/encounter, with the highest acuity diagnoses sequenced 1st
Sequencing Of Codes
65
• With added laterality, need greater documentation from your MD’s
• Hypertensive Retinopathy H35.03– H35.031 right eye– H35.032 left eye– H35.033 bilateral– H35.039 unspecified (this would be a ?? for
billing most likely!!)– Code also any associated hypertension (I10)
Specificity Of Coding
66
• Sepsis– Unspecified organism, A41.9, if type of
infection is not specified– Sepsis d/t MRSA A41.02– B95.62 MRSA as the cause of conditions
classified elsewhere • When the infection does not have a combo code
that includes the causal organism
Chapter 1 – Infectious & Parasitic Diseases A00-B99
67
• HIV infections– Admit for HIV-related condition, principal
diagnosis should be B20, followed by code for HIV-related condition
Chapter 1 – Infectious & Parasitic Diseases A00-B99 -2
68
• UROsepsis – The term urosepsis is a nonspecific term. It is not to be considered synonymous with sepsis. Iy has no default code in the Alpha index.
• QUERY THE DOCTOR!!!• Sepsis with organ dysfunctioin• - follow Severe sepsis guidance
SEPSIS
• Requires two codes• First code for underlying systemic infection
followed by a code from subcategory R65.2
• Casual organism should be documented; if not – assign A41.9 unspecified for the infection. (where would you look)
SEPSIS - SEVERE
• The neoplasm table should be referenced first
• Anemia also w /malignancy– If encounter is for mgmt of anemia asso w
/malignancy, and tx is only for anemia, principal dx = malignancy code, followed by anemia code D63.0

75
• Chronic pain syndrome G89.4 vs. chronic pain G89.2– Provider must specifically document which
condition• Hemiplegia - Dominant/non-dominant side
G81– For ambidextrous patients, the default should
be dominant– Left side affected, the default is non-dominant– Right side affected, the default is dominant
Chapter 6 – Diseases Of The Nervous System G00-G99
76
• Pain – category G89– Used in conjunction with codes from other
categories to provide more detail about acute or chronic pain, neoplasm pain, or post-procedural pain
– Can be listed as principal diagnosis– When pain control or pain mgmt is reason for
admit, the underlying cause and site of pain should be reported as additional dx, if known.
Chapter 6 – Diseases Of The Nervous System G00-G99 -2
77
• If encounter is for any other reason, and dx has not been established, assign the code for the site of pain 1st, followed by code from G89
Chapter 6 – Diseases Of The Nervous System G00-G99 -3
• Assigning glaucoma codes:– Assign as many codes from category H40, as
needed, to identify the type of glaucoma, the affected eye, and the glaucoma stage.
Chapter 7 – Diseases Of Eye And Adnexa H00-H59
79

Chapter 9 – Diseases Of The Circulatory System I00-I99
80
• Hypertension with Heart Disease I11– Heart conditions classified to I50 or I51.4-
I51.9 are also assigned to, a code from category I11 when a causal relationship is stated (due to hypertension) or implied (hypertensive)
– Use an additional code from category I50– Outlines the different conditions, i.e.,
Cardiomegaly, Mycarditis, Left Ventricular failure, etc.
Chapter 9 – Diseases Of The Circulatory System I00-I99 -2
81
• Hypertensive chronic kidney disease/CKD I12 – Cause and effect relationship is presumed– Need add’l code to identify the stage of CKD

must be doc’d
Chapter 9 – Diseases Of The Circulatory System I00-I99 -3
82
• Sequelae of cerebrovascular disease I69– Used to indicate conditions in I60-I67 as the
cause of sequelae. The “sequelae” include conditions specified as such or as residuals which may occur at any time after the onset of the causal condition
– I.E., CEREBRAL INFARC – also have to document and code if tPA or rtPA in different facility in 24 hrs. (Z92.82—review)
Chapter 9 – Diseases Of The Circulatory System I00-I99 -4
83
• CEREBROVASCULAR DISEASE• Use added codes – identify presence of

– Exposure to tobacco smoke– Hx. Of tobacco use– Hypertension– Occupational exposure to tobacco smoke
Chapter 9 – Diseases Of The Circulatory System I00-I99 -5
• Tobacco dependence• Tobacco Use• (see where the History from the Physician
and the Social Hx. Is Important).
Chapter 9 – Diseases Of The Circulatory System I00-I99 -6

Chapter 10 – Diseases Of Respiratory System (J00-J99) -2
89
• L89 codes for Pressure Ulcer are combination codes that identify the site as well as the stage of the ulcer
• Assignment of the pressure ulcer stage should be guided by clinical documentation of the stage
• Assign code for the highest stage reported for that site
Chapter 12 – Diseases Of Skin& Subcutaneous Tissue L00-l99
90
• Site and laterality– Designations– Represents the bone, joint or muscle involved– Where more than one bone, joint or muscle is
involved, such as osteoarthritis, use the assigned “multiple sites” code; if not available, use multiple codes to indicate the sites
– Bone vs. Joint – Certain conditions where the bone may be affected at the upper & lower end; site designation will be the bone, not the joint
Chapter 13 – Disease Of Musculoskeletal (M00-M99)
91
• Bone, joint or muscle conditions that are the result of a healed injury are coded to this chapter
• Chronic or recurrent conditions are also coded to this chapter
• Pathologic fractures are coded with 7th character D for encounters after active treatment is completed, if routine healing is occurring
Chapter 13 – Disease Of Musculoskeletal (M00-M99) -2
92
• M80 category is used for any patient with known osteoporosis who suffers fracture, even if pt had minor fall or trauma, if that fall would not usually break a normal bone
• Osteoporosis without pathological fracture M81 is used for patients who do not currently have a pathologic fracture d/t osteoporosis, even if they have had a fracture in the past
Chapter 13 – Osteoporosis
93
• Osteoporosis with pathological fracture, M80, is used for pts who have a current pathologic fracture at the time of the encounter
Chapter 13 – Osteoporosis #2
• Stages of chronic kidney disease (CKD)• If both a stage of CKD and ESRD are
documented, then assign code N18.6 only • Patients who have had kidney transplant
may still have some form of CKD, because the transplant may not fully restore kidney function. Therefore, presence of CKD alone does NOT constitute a transplant complication.
Chapter 14 – Diseases Of Genitourinary (N00-N99)
95
• A41.9 Sepsis, unspecified organism –Septicemia, unspecified (Chapter 1 Infectious & Parasitic Diseases)
• Severe Sepsis – R65.20 – code first underlying infection, and use additional code to identify specific organ
• Urosepsis – cannot code, code to condition
Chapter 18 – Symptoms, Signs & Abnormal Clinical & Lab
Findings (R00-R99)
96
• Septic Shock– Circulatory failure associated with severe
sepsis; represents a type of acute organ dysfunction. Underlying infection sequenced first, followed by code R65.21 Severe sepsis with septic shock. Add additional codes for other acute organ dysfunction
Chapter 18 – Symptoms, Signs & Abnormal Clinical & Lab
Findings (R00-R99) -2
97
• Use of symptom codes are acceptable for use when a related diagnosis has NOT been established by the provider
• Use a symptom code with a diagnosis code may be reported when the sign or symptom is NOT routinely associated with that diagnosis
• Signs or symptoms that are associated routinely with a disease process should NOT be assigned as additional codes
Chapter 18 – Signs/Symptoms Codes
98
• R29.6 Repeated falls is used when a patient has recently fallen and reason for the fall is being investigated.
• Z91.81 Hx falls is used when a pt has fallen in the past and is at right for future falls
• When appropriate, both of the above codes may be assigned together
Chapter 18 – Signs/Symptoms Codes -2
99
• R53.2 is the lack of ability to use one’s limbs or to ambulate d/t extreme debility.
• It is NOT associated with neurologic deficit or injury, code R53.2 should NOT be used for cases of neurologic quadriplegia.
• It should only be assigned if functional quadriplegia is specifically documented in the medical record
Chapter 18 – Functional Quadriplegia
100
• An example S42.321D. Displaced transverse fracture of shaft of humerus, right arm, subsequent encounter for fracture with routine healing
• This means more specific documentation from the physician (the initial encounter of treatment is usually in the Emergency room).
Chapter 19 – Injury, Poisoning & Certain Other Consequences of
External Causes S00-T88
101
• A fracture not indicated as open or closed should be coded to closed
• A fracture not indicated whether displaced or not should be coded to displaced
Chapter 19 – Injury, Poisoning & Certain Other Consequences of
External Causes S00-T88 -2
102
• When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the code for the adverse effect of the drug (T36-T50)
• The code for the drug should have a 5th or 6th character “S”
•
Chapter 19 – Drug Toxicity
103
• When coding a poisoning or reaction to the improper use of a medication, i.e. overdose, wrong substance given or taken in error, assign the appropriate code from categories T36-T50
• The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined)
Chapter 19 – Poisoning
104
• Underdosing refers to taking less of a medication than is prescribed by a provider or a manufacturer’s instruction
• Assign T36-T50 with 5th or 6th character of “6”• Codes for underdosing should never be
assigned as principal dx• Noncompliance (Z91.___) or complication of
care (Y63.___) codes are to be used with an underdosing code, if known
Chapter 19
105
• These codes are secondary codes for use in any health care setting
• These codes capture how the injury happened (cause) or the intent
• Assign the external cause code with the appropriate 7th character for each encounter for which the injury or condition is being treated (initial, subsequent or sequela)
• What happened? V03 pedestrian injured in collision with car, pick-up truck or van
Chapter 20 – External Causes of Morbidity (V00-Y99)
106
• For use in any healthcare setting• May be used as either a principal
diagnosis or secondary code• Certain Z-codes may only be used as
principal diagnosis
Chapter 21 – Factors Influencing Health Status and Contact with
Health Services (Z00-Z99)
107
• Z code should not be used if treatment is directed at a current acute disease
• Exceptions– First listed, followed by the diagnosis code
when a patient’s encounter is solely to receive radiation therapy Z51.0
– Code also condition requiring care
Chapter 21 – Z Codes
108
• Factors Influencing Health Status and Contact With Health Services Z00-Z99
• Former V codes are now Z codes• Provided for occasions when circumstances
other than a dx, injury or external cause are recorded
• Several codes have been expanded, i.e. personal and family hx
• Now have a code for patients blood type, i.e. Z67
CHAPTER 21 – Z Codes
109
• No longer have V57 codes • Code the underlying condition, i.e. injury,
etc. with the appropriate 7th character for subsequent encounter
• Z68 BMI is divided into adult and pediatric codes (Adults = age 21 or older)
• RD in facility can assist with documenting the BMI
Chapter 21 – Z Codes -2
110
• Code Z92.82 when tsf facility has admin tPA within 24 hrs prior to admit (usually with new dx of MI or CVD)
• Aftercare Z codes should NOT be used for aftercare of fractures
• For aftercare of fractures, assign fracture code with 7th character D for subsequent encounter
