Coding Overview and the Data Quality Statement
DQMC – March 2011
Goal
• Quality data on which to base sound decisions– For you– For your Department– For your Commander– For your Service– For the Military Health System (MHS)
Purposes of Coding• Validates medical necessity of services
based on diagnosis• Identifies why patients are being seen • Identifies and quantifies the services you have
provided• Permits retrieval of information for users
• Research and Benchmarking• Administrative and funding decisions• HEDIS reporting
• Key to Population Health - identify trends
Medical Record Documentation
Complete Documentation
Correct Coding
Appropriate Reimbursement and Workload
The critical factor in determining the level of care:
Not what you did….but what you documented!
Types of Coding• ICD-9-CM
– Diagnoses used for all types of encounters/admissions– Procedures used only for inpatients– MS-DRGs are based upon these codes– Updated annually 1 October
• CPT– E&M and procedure codes– Updated annually 1 January
• HCPCS– Supplies, pharmaceuticals/injectables– Updated annually 1 January
Background Information
• ICD-9-CM: Clinical Modification developed in the US and implemented in 1979– Volumes 1&2 Diagnosis Codes (used by all providers)– Volume 3 Procedure Codes (used by hospitals for
inpatient reporting)• ICD-10: Diagnosis classification system
developed by the World Health Organization to replace ICD-9
• ICD-10-CM: US Clinical Modification for ICD-10 diagnosis classification system
• ICD-10-PCS: US procedure classification system to replace ICD-9-CM Volume 3
ICD-10• Tenth addition of ICD was issued in 1993
– Currently used in Europe and Canada
• 5010 electronic transaction standards requirement by 1 January 2012
• US ICD-10 Compliance date is 1 October 2013– ICD-10-CM has expanded upon ICD-9-CM– ICD-10-PCS requires building a 7 character code– Requires coding and documentation training– NO GRACE PERIOD FOR IMPLEMENTATION
ICD-9 & ICD-10 Code Freeze• The last regular, annual updates to both ICD-9-CM and
ICD-10 code sets will be made on October 1, 2011.• On October 1, 2012, there will be only limited code updates
to both the ICD-9-CM and ICD-10 code sets to capture new technologies and diseases as required by section 503(a) of Pub. L. 108-173.
• On October 1, 2013, there will be only limited code updates to ICD-10 code sets to capture new technologies and diagnoses. There will be no updates to ICD-9-CM, as it will no longer be used for reporting.
• On October 1, 2014, regular updates to ICD-10 will begin.
AHIMA Coder ICD-10 Training Strategy
• Increase ICD-10-CM/PCS awareness• Review and refresh knowledge of A&P• Begin studying ICD-10-PCS definitions• Learn about the General Equivalency Mappings
(GEMS) between ICD-9-CM and ICD-10-CM/PCS• Provide training on clinical documentation
improvement (CDI) strategies
RECOMMENDED ACTION STEPS2009 thru first half of 2011
AHIMA Coder ICD-10 Training Strategy
• Coding Manager’s Challenge:
50 hours of training:– 16 hours ICD-10-CM– 24 hours ICD-10-PCS– 10 additional hours of practice
Key is to provide appropriate training to the right
individuals at the right time
ICD-10 Final Rule
• Inpatient coders on ICD-10-CM/PCS recommends 50 hours of training
• Outpatient coders on ICD-10-CM recommends 10 hours of training
• Physicians recommends 8 hours of training
• Auxiliary staff recommends 8 hours of training

ICD-9-CM vs. ICD-10-PCS
ICD-9-CM (vol. 3):• Minimum of 3

ICD-10 AHIMA Training Example - ERCP
Index: Lithotripsy, see Fragmentation. The Endoscopic Retrograde Cholangiopancreatography (ERCP) with lithotripsy is coded to Fragmentation. ERCP is performed with a scope entering through the mouth to the biliary system via the duodenum, so the approach value is Via Natural or Artificial Opening Endoscopic. 16

Coding Basics
• Codes are assigned based on documentation • Diagnosis codes are assigned differently based
on the setting (inpatient or outpatient)• Military Health System has special coding
requirements and are needed to accurately reflect services that are unique to the military.

DoD Unique Diagnosis Codes
• DoD Extender Codes• Root code V70.5 Health examination of
defined subpopulations• V70.5_0 Armed Forces medical exam• V70.5_1 Aviation Exam• V70.5_2 Periodic Health Assessments
(PHA) or Prevention Assessment• V70.5_3 Occupational exam
DoD Unique Procedure Codes
Utilize existing codes for unique reporting
• 99199 is used to identify the Institutional component of an APV
• Case Management:– G9002 Monthly CM Summary Reporting – Acuity level 1– G9005 Monthly CM Summary Reporting – Acuity level 2– G9009 Monthly CM Summary Reporting – Acuity level 3– G9010 Monthly CM Summary Reporting – Acuity level 4– G9011 Monthly CM Summary Reporting – Acuity level 5
Inpatient Record
• An admission generates an institutional record based upon the MS-DRG = SIDR– MS-DRG based upon correct assignment of ICD-9
diagnoses and procedures• MS-DRG accuracy is reported for 5.a.• Data elements within MS-DRG is on the Review List (C.5.c-d)
– All diagnoses, any Procedures done, Sex and Age of patient, Discharge/Disposition
– Medical Severity DRGs (MS-DRG)• Diagnoses requires supporting Present on Admission (POA)
Indicators • CCE updated to add POA • CHCS 11-segment SIDR implemented Nov 2010
Inpatient Record - Rounds
• An inpatient professional services encounter or rounds (formerly called IBWA) = “A” CAPER– Services performed by the Attending Service– E&M and procedures performed– Same records as the MS-DRG audit– Inpatient Consults and follow-up captured in the “B”
CAPER
Inpatient Record - Rounds
• Auditing Sampling Methodology (for questions C.5.f,g,h)
– One calendar day of the attending professional services during each audited hospitalization will be audited from the randomly selected sample. – For hospitalizations which begin and terminate the same
calendar day, that calendar day will be audited. – For all other hospitalizations, the registration number will
determine if services for the first or second calendar day will be audited.
– Odd registration numbers will be audited for the first day and even registration numbers will be audited for the second day.
Outpatient Record
• Professional services are coded and generate a “B” CAPER
• The following services are considered outpatient:– Clinic– Emergency Department– Observation status with doctors written order– APV (Same Day Surgery)– Consults – Rounds are captured in the “A” CAPER
Coding Compliance
• The key to coding compliance is• Correct documentation • Correct codes• Correct guidelines• Standardized audit methodology
Timeliness
• Question 2 - Was your facility compliant with the following metrics?– What percentage of Outpatient Encounters,
other than APVs, have been coded within 3 business days of the encounter? (B.6.(a))
– What percentage of APVs have been coded within 15 days of the Encounter? (B.6.(b)
– What percentage of Inpatient records have been coded within 30 days after discharge? (B.6.(c))
Completeness
Encounters/admissions must be complete in order to code:
• Patient identification is correct and present• Dated• Signed (ink or electronic signature)• Legibility (if paper)• Documentation is complete
– Patient medical history– Reason for encounter– Assessment and Plan– Surgical report (if applicable)
• Review List C.5.a,b– Percentage of inpatient medical records
located?– Percentage of documentation that was
complete.• Questions 6a, 7a
– Is adequate documentation of the encounter selected to be audited available? (C.6.a, C.7.a)
Completeness
Accuracy
• Questions 5a-d, 6b-d and 7b-c• Was the MS-DRG correct (inpatient)?• Was the Primary Diagnosis (outpatient)
present and in the first position?• Was the E&M code correct and present
(non-APVs)?• Were CPT procedure codes correct?• NOTE In the absence of MHS guidance, follow civilian
coding guidelines and/or conventions.
Reporting Coding Accuracy
TMA/UBU calculation methodology:
Number of correct codes
Total number of codes• Provides standardized business rules
across MHS • More accurate representation of metric
Consistency
• Was there a sudden change in metrics - what happened?– Software change– Table update– Change in staff– System is down
• Did you file a trouble ticket?• Did you put a comment on your Data Quality Statement
to explain identified problem and estimated correction date?
