of ICD-9-CM
 Annual update to ICD-9 is provided

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.
Official Guidelines for
Coding & Reporting

Four Sections:
- Section I
- Section II
- Section III
- Section IV
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.
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.
Guidelines

Multiple coding
- Use additional code
- Code first
- If applicable, code any causal
condition first
Acute (or subacute) and chronic
conditions
Combination code versus multiple code
Late Effect

Residual condition that develops after
acute phase of illness or injury has ended
- No time limit on reporting
For example, traumatic arthritis (residual)
following fracture of the left ankle three
years ago (cause) (716.17, 905.4)
Combination code assigned, for example
aphasia due to cerebrovascular accident 6
months ago (438.11)
