ICD-9-CM Coding Guidelines Presented by Cheryl Crosswhite, CPC
ICD-9-CM Official Guidelines for Coding and Reporting • Partial Freeze of Revisions: October 1, 2011 – last major update of ICD-9-CM • Annual update to ICD-9 is provided online on the CDC website: http://www.cdc.gov/nchs/icd/icd9cm_addenda_guidelines.htm
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)
