POS code 61: Comprehensive Inpatient Rehabilitation Facility.

The CMS definition

A facility that provides comprehensive rehabilitation services under the supervision of a physician to inpatients with physical disabilities. Services include physical therapy, occupational therapy, speech pathology, social or psychological services, and orthotics and prosthetics services.

That is the description CMS publishes for POS 61, Comprehensive Inpatient Rehabilitation Facility, in the Place of Service Code Set and in chapter 26 of the Medicare Claims Processing Manual. In the manual’s table it carries the Facility rate (F) designation for payment under the Physician Fee Schedule.

What it means in plain terms

POS 61 is for an inpatient rehabilitation facility that provides comprehensive rehabilitation under physician supervision. CMS names it specifically as an example of the more exact inpatient code a practitioner may report instead of POS 21.

When it is used

• A physician or practitioner sees a registered inpatient in a comprehensive inpatient rehabilitation facility.
• For the outpatient counterpart, CMS lists POS 62 (Comprehensive Outpatient Rehabilitation Facility), which carries the non-facility rate.

Billing implications (Medicare)

The manual marks POS 61 F, so Medicare physician fee schedule services are paid at the facility rate. CMS says reporting inpatient hospital POS 21 is the minimum requirement for a registered inpatient; if the practitioner knows the exact setting, the more specific code may be used, and POS 61 is CMS’s example for a Comprehensive Inpatient Rehabilitation Facility.

The general rule in section 10.6 of the manual is that the POS code “generally” reflects the actual setting where the beneficiary receives the face-to-face service, with two exceptions: a registered hospital inpatient or outpatient is reported with the hospital code regardless of where the encounter happens. The code goes in item 24B of the paper Form CMS-1500 or the matching field of the 837P. A claim with a missing or invalid POS is returned as unprocessable.
