HCPCS C1600: Catheter, bladed, vascular preparation

CPT (Level I HCPCS) codes are five-digit numeric codes maintained by the American Medical Association (AMA) that describe medical procedures and services provided by physicians and other health professionals. Meanwhile, C-Codes (Level II HCPCS) are temporary alphanumeric codes (starting with 'C') established by CMS to report new, technology-intensive items, procedures, and services that do not yet have other permanent codes, often for use by hospitals and ASCs under the Medicare OPPS/ASC payment systems.

Transitional Pass-Through (TPT) payment is a mechanism under Medicare for new, high-cost devices (or drugs/biologicals) that meet specific criteria. It allows for separate payment for the device, beyond the bundled payment for the procedure, for a limited time (usually 2 to 3 years) to facilitate patient access to innovative technologies while cost data is collected for permanent payment rate setting.

No. C1600 is a facility-specific code (Hospital Outpatient Department or Ambulatory Surgical Center) used to report the device itself. The physician bills for their professional service using the appropriate CPT code (e.g., 36902, 36905). The cost of the device is included in the facility's claim using C1600.
