TL;DR
C9606 is a Level II code from the C section (hospital outpatient prospective payment system, temporary codes), in use since 2013: "Percutaneous transluminal revascularization of acute total/subtotal occlusion during acute myocardial infarction, coronary artery or coronary artery bypass graft, any combination of drug-eluting intracoronary stent, atherectomy and angioplasty, including aspiration thrombectomy when performed, single vessel". None of the October 2026 PFS, DMEPOS, CLFS, OPPS or ASC files lists a national amount for C9606; its HCPCS pricing indicator is 53 (statute). MUE limits for C9606: practitioner 1 (MAI 3, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 3, Code Descriptor / CPT Instruction). C9606 is a primary code for 9 add-on codes (0914T, 92972, 92973, 92974). In the NCCI PTP files v323r0 C9606 appears in 10 practitioner pairs as column 2 and 236 as column 1 (most often with 0659T, 33500, 33501), and in 8 hospital outpatient pairs as column 2 and 232 as column 1. 2 active LCDs and 2 billing and coding articles list C9606 across 9 states: L33623 (Percutaneous Coronary Intervention), L34761 (Percutaneous Coronary Interventions), A56823, A57479. OPPS status indicator C: Inpatient procedure. HCPCS record: BETOS P2F (major procedure, cardiovascular - other); pricing indicator 53; type of service 2 (surgery). Nearby codes: C9607, C9604, C9602, C9610.
C9606 descriptor and code status
The October 2026 HCPCS Level II file describes C9606 as “Percutaneous transluminal revascularization of acute total/subtotal occlusion during acute myocardial infarction, coronary artery or coronary artery bypass graft, any combination of drug-eluting intracoronary stent, atherectomy and angioplasty, including aspiration thrombectomy when performed, single vessel”. It sits in the C section (hospital outpatient prospective payment system, temporary codes), listed with the other C codes. Although searches often call it the "C9606 CPT code", C9606 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.
