CMS Place of Service code set, Comprehensive Inpatient Rehabilitation Facility

POS 61 is one of the long-standing codes that CMS lists without a date, meaning it was in effect on or before January 1, 2003 (Medicare Claims Processing Manual, Pub. 100-04, chapter 26, section 10.5).

Facility or non-facility rate for POS 61

Medicare pays a physician fee schedule service billed with this code at the facility rate. The facility rate carries a smaller practice-expense component than the non-facility rate, because in a facility setting the facility, not the practitioner, bears the cost of the room, the staff and most supplies; where the facility is a Medicare provider it is paid for those costs on its own claim.

Chapter 12, section 20.4.2 of the Medicare Claims Processing Manual lists this setting as “Comprehensive Inpatient Rehabilitation Facility” on its facility list. The rule behind the list is that the code reflects where the beneficiary received the face-to-face service, except that services to a registered hospital inpatient or outpatient are paid at the facility rate wherever the encounter took place.

An inpatient rehabilitation facility is paid at the facility rate, and a practitioner who knows a registered inpatient is in one may report POS 61 rather than POS 21 (chapter 26, section 10.5).

Not every service has two rates: when the facility and non-facility amounts are the same, as they are for the professional component of a diagnostic test, the place of service does not change the payment. Outpatient therapy and comprehensive outpatient rehabilitation facility services are always paid at the non-facility rate.

Denials when POS 61 does not fit the claim

A place of service that conflicts with the procedure, the patient's registration or the payer's policy comes back with one of three codes. Claim adjustment reason code 5 means the procedure code or bill type is inconsistent with the place of service; reason code 58 means the payer considers the setting inappropriate or invalid for the service; and remark code M77 marks a missing, incomplete, invalid or inappropriate place of service. Medicare returns a line whose POS is missing, unassigned or incompatible with a site-specific procedure as unprocessable with CARC 16 and M77, so the fix is a corrected claim rather than an appeal (Pub. 100-04, chapter 26, section 10.6).

Does POS 61 pay the facility or the non-facility rate?

The facility rate. Medicare Claims Processing Manual, Pub. 100-04, chapter 26, section 10.5 designates POS 61 F, so a physician fee schedule service billed with it is paid at the facility rate, the lower practice-expense amount paid when the setting rather than the practitioner carries the cost of space, staff and supplies. Chapter 12, section 20.4.2 lists it as "Comprehensive Inpatient Rehabilitation Facility" on the facility list. Services whose two rates are equal, such as the professional component of a diagnostic test, pay the same either way (chapter 12, section 20.4.2).

When should a claim use POS 61?

An inpatient rehabilitation facility is paid at the facility rate, and a practitioner who knows a registered inpatient is in one may report POS 61 rather than POS 21 (chapter 26, section 10.5).
