Billing and Coding: Percutaneous Coronary Intervention

PCI (CPT 92920-92944) is covered when medically necessary for percutaneous treatment of coronary artery lesions using angioplasty, atherectomy, or stenting, with coding rules that govern single-vessel reporting and bridging-lesion reporting (e.g., 92928 for a single left-main stent). Claims must include appropriate ICD-10-CM diagnosis codes, required referring/ordering physician information (when applicable), and procedural documentation (procedure note, angiographic and intravascular imaging) supporting medical necessity; procedures and codes remain subject to NCCI and OPPS edits. Repeat diagnostic angiography within three months requires explicit documentation of the clinical need when no new symptoms or signs are present.
