Summary & Overview
CPT 0366T: Deleted Interventional Cardiovascular Procedure
CPT code 0366T denotes a deleted interventional cardiology procedure code, removed effective January 1, 2019. The code historically represented an intracoronary or catheter-based cardiovascular service performed in a catheterization laboratory or procedural suite. Its deletion is relevant to coding accuracy, claims adjudication, and historical recordkeeping for providers performing coronary diagnostic or therapeutic interventions. National payers and clearinghouses rely on correct code usage to process claims and reconcile historical encounters.
Key payers included in this analysis are Aetna, Cigna Health, UnitedHealthcare, and Medicare. BUCA is an internal benchmark and is not listed as a payer. Readers will find an overview of the code's status, clinical context linking it to coronary interventions, and references to related active CPT codes that clinicians and coders may use for comparable services. The publication summarizes common associated diagnoses for which this type of procedure would have been billed and points to related CPT procedures for stenting, angioplasty, catheter placement for coronary angiography, and intravascular ultrasound.
This summary is intended to inform coding specialists, billing managers, and clinical leaders about the deleted status of 0366T, its clinical domain, and where to look for alternative active codes when documenting coronary interventional services. Data not available in the input: specific historical descriptor text beyond the deletion notice and payer-specific reimbursement details.

Clinical & Coding Specifications
Clinical Context
A 64-year-old male with a history of hypertension and hyperlipidemia presents to the emergency department with exertional chest pressure and shortness of breath. Initial ECG and troponin are non-diagnostic but concern remains for unstable coronary ischemia. Coronary angiography is performed via right radial artery access to evaluate for obstructive coronary artery disease. During the diagnostic catheterization, a significant focal stenosis of the proximal left anterior descending artery is identified and treated with percutaneous transluminal coronary angioplasty and stent placement during the same session. The patient is monitored in a cardiac observation unit post-procedure and discharged on guideline-directed antiplatelet therapy.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of a procedure | Use when a distinct E/M visit is medically necessary and documented on the day of the angiography/PCI procedure |
59 | Distinct procedural service | Use to indicate a separate, distinct procedure when multiple procedures are performed in separate anatomic sites or sessions |
