Rehabilitation Hospital Coding
The Central Office on ICD-9-CM has continued to receive questions regarding the coding and sequencing of diagnoses in inpatient rehabilitation facilities (IRF). These facilities are required to complete a data collection instrument called Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI), as well as a claim form. The IRF-PAI requires the assignment of ICD-9-CM diagnosis codes for the etiologic diagnosis to indicate the condition for which the patient is receiving rehabilitation, as well as other comorbid conditions.

Article Overview
This article addresses coding and sequencing questions for inpatient rehabilitation facilities and explains how reporting differs between the claim form and the IRF-PAI. It is aimed at hospital coders, rehabilitation facilities, and health information professionals who work with ICD-9-CM diagnosis reporting, especially when rehab stays overlap with active conditions or comorbidities. The article also references Medicare guidance and Coding Clinic context to clarify the scope of the instructions discussed.
Why This Topic Matters
Rehabilitation settings often involve two reporting frameworks, and understanding which guidance applies helps support consistent diagnosis reporting, sequencing, and compliance in IRF settings without relying on the wrong set of instructions.
