Facility or non-facility rate for POS 49

Medicare pays a physician fee schedule service billed with this code at the non-facility rate. The non-facility rate carries the larger practice-expense component, because the practitioner bears the cost of the space, the clinical staff, the equipment and the supplies used for the service.

Chapter 12, section 20.4.2 of the Medicare Claims Processing Manual lists this setting as “Independent Clinic” on its non-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 independent clinic is not part of a hospital, serves outpatients only and is used when no other POS code describes the location, according to the CMS definition. Medicare pays physician services there at the non-facility rate (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 49 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).
