Inpatient Rehabilitation – Coding Stroke Deficits on the IRF PAI & UB:04

By Nirmala Sivakumar, CCS, CDIP

This is a common error I see while doing audits of coding at Inpatient Rehabilitation Facilities.

How should deficits from a stroke be recorded on the IRF PAI? Do the codes differ on the UB:04?

If the patient is admitted to inpatient rehabilitation following an acute stroke, the deficits from that stroke should be recorded with R codes (Chapter 18 of ICD-10-CM manual) on the IRF PAI. If patient presents with hemiparesis, G81.XX is recorded. The stroke resolves in acute care and it is the deficits that are being addressed in rehab, so they are recorded using acute codes.

For UB:04 coding, since IRF is considered post-acute care, the stroke deficits including hemiparesis will be recorded using Sequalae codes (Category I69, sequelae of cerebrovascular disease). Coders who also provide ICD-10-CM codes for the IRF-PAI must be aware of this and make sure they are giving accurate codes to the PPS coordinator.


Inpatient Rehab Coding
IRF-PPS coding guidelines differ from inpatient guidelines and can pose a challenge to even seasoned coders. IRF coding authority, Nirmala Sivakumar, CCS, CDIP, helps you to meet the challenge.
