A hospital outpatient, for Medicare purposes, is defined in Chapter 6 (Hospital Services Covered Under Part B) of the Medicare Benefit Policy Manual, section 20.1 - Outpatient Defined, as follows: "A person who has not been admitted by the hospital as an inpatient but is registered on the hospital records as an outpatient and receives services (rather than supplies alone) from the hospital."

Pass-Through Payment Status and New Technology APC
APC (Ambulatory Payment Classification)
APC Status Indicators / CodesThe status indicator provides information on the type of service represented by the APC. Common indicators are below; Addendum D1 of the 2006 HOPPS Final Rule lists them all. Addendum D1. Payment Status Indicators for HOPPS
Coding
HCPCS C-Codes
The HOPPS included "C" codes, or "pass-through" codes. Medicare created over 90 "pass-through" categories of devices, each category with its own specific "C" code. If a hospital used a device that fell into a pass-through category, they could put the appropriate C-code on the bill they submitted to Medicare for additional payment. These were commonly known as "pass-through" payments and were designed to expire after two to three years, after which this additional payment would be folded into the relevant Ambulatory Payment Classification (APC) payment rates.
Though the pass-through
payments for most C-codes no longer exist, Medicare does require that C-codes
continue to be included on hospital claims paid under the OPPS. This is done
so that Medicare can adequately capture the resources required to provide
services, and use this resource information to establish adequate payment rates
in the future. In fact, Medicare has defined certain procedures as being
device-dependent, and claims for these procedures will be denied if they don’t
also include the necessary C-codes. Surgical DiscountingOutpatient Code Editor identifies the following situations so that Pricer will apply surgical discounting to the following situations:
o The highest paying APC will not be discounted. o All other type T procedure will be discounted 50%. o A HCPCS code with modifier 73 (terminated prior to anesthesia) will be discounted 50%. o A type-T procedure HCPCS code billed with modifier 50 (bilateral), is similar to billing for two procedures, one performed on the right side, and one on the left side. Therefore, when modifier 50 is billed, § If it has the highest paying APC of the type T procedures billed for the same date of service, only one of the procedures (right or left) will be discounted (100% + 50%). This will result in a payment of 150% of the APC. § If another type T procedure billed on the same date of service has the highest APC, both procedures (right and left) will be discounted (50% + 50%). This will result in a payment of 100% of the APC.
