1 ICD-9-CM Coding Guidelines
Chapter 4 ICD-9-CM Coding Guidelines

2 ICD-9-CM Official Guidelines for Coding and Reporting
Rules developed by the cooperating parties for the ICD-9-CM to accompany and complement the official conventions and instructions provided within ICD-9-CM Companion to ICD-9-CM (continued)

3 ICD-9-CM Official Guidelines for Coding and Reporting
Cooperating parties consist of: American Hospital Association (AHA) AHIMA CMS NCHS

4 HIPAA Alert! HIPAA regulations require providers and third-party payers to adhere to ICD-9-CM Official Guidelines for Coding and Reporting. A violation of coding guidelines is a violation of HIPAA.

5 Official Guidelines for Coding and Reporting
Four sections: Section I Section II Section III Section IV

6 Historical Perspective
Bertillon International Statistical Classification of Causes of Death International Classification of Diseases (ICD) ICD-9-CM ICD-10-CM and ICD-10-PCS (future)

7 General Guidelines Use both the ICD-9-CM Index to Diseases and the Tabular List of Diseases. Locate term in the Index to Diseases first, and verify the code in the Tabular List of Diseases. Assign the highest level of digits available.

8 Guidelines Signs and symptoms that are integral to the disease should not be assigned as additional codes. The etiology and manifestation convention requires two codes to be reported to completely describe a single condition. (continued)

9 Guidelines Multiple coding Acute (or subacute) and chronic conditions
Use additional code Code first If applicable, code any causal condition first Acute (or subacute) and chronic conditions Combination code versus multiple code

10 Late Effect Residual condition that develops after acute phase of illness or injury has ended No time limit on reporting Combination code assigned For example, painful cicatrix following severe burn to the elbow or left-sided paralysis due to previous cerebrovascular accident (CVA)

11 General Procedure Guidelines
Based on anatomy rather than surgical specialty Numeric codes Use both Index to Procedures and Tabular List of Procedures (continued)

12 General Procedure Guidelines
Index to Procedures main terms organized in alphabetic order according to type of procedure Report codes using highest number of digits available — omit code (continued)

13 General Procedure Guidelines
Common key terms: Application Closure Correction Destruction Division Incision Insertion Operation Procedure Release Removal Repair (continued)

14 General Procedure Guidelines
Common key terms: Resection Revision Suture Test Therapy Transfer (continued)
