List of New C Codes for ASC Reporting

On December 21, CMS released the following Transmittal 11762 with new C codes to be used by ASCs (Ambulatory Surgery Centers): https://www.cms.gov/files/document/r11762cp.pdf   

Please note these C codes are for ASC coding only!

Note, this information is for those responsible for adding or checking the C codes on the ASC claim.Usually coders do not have to do this however auditors (and sometimes coders)  may be asked to verify them. The C series of HCPCS (“C codes”) reports drug, biological, and device codes that must be used by ASCs and/or Outpatient Prospective Payment System (OPPS) hospitals for reporting facility (technical) services.

What are the new C codes?

CMS instituted the use of C code to better facilitate ASC coding and billing. Report the C codes with Category I CPT codes. OPPS Status Indicator E1 will allow additional payment for packed services for ASC.

The following twenty-six new procedures are separately payable in the ASC setting and became effective on January 1, 2023 for ASC coding of Medicare patients that are reported IN ADDITION TO THE CPT I PROCEDURE CODE. Some other payors may have adopted them as well so facilities may want to check with their payors.

For example, at an ASC, code C7519 Catheter placement in coronary artery(ies) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation, with catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) including intraprocedural injection(s) for bypass graft angiography with intravascular doppler velocity and/or pressure derived coronary flow reserve measurement (initial coronary vessel or graft) during coronary angiography including pharmacologically induced stress would be reported with codes 93455, +93571‐ +93572.   The Transmittal R11762CP at link above will give the Primary and secondary HCPCS codes that the C codes should be reported with.
