The patient's medical record must fully document medical necessity for the cardiac catheterization and support the diagnosis and procedures billed.
Each claim must include ICD-10-CM diagnosis code(s) that accurately reflect the patient's condition and reason for the procedure and these codes must be linked to the CPT procedure codes on the claim.
When a referring/ordering physician is required, the name and NPI of the referring/ordering physician must be reported on the claim; for extra-cardiac angiographic services the treating physician's name and NPI must be submitted in items 17/17a of CMS-1500 or electronic equivalent.

Medicare Part B covers the professional component of cardiac catheterization and coronary angiography when performed in hospital inpatient and outpatient facility settings.
Diagnostic cardiac catheterization performed in an office setting (where permitted) is covered under Medicare Part B for both professional and technical components.
Global and technical component procedures are covered under Part B when performed under personal physician supervision in an IDTF, free-standing facility, physician office, or physician-directed clinic (physician present in room for entire procedure).
Cardiac catheterization and coronary angiography are covered when the medical record documents medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests that support the procedure.
An ECG is covered when the result is relevant to the management, diagnosis, or treatment of the patient.
A separate ECG on the same day as a cardiac stress test is payable only when it provides additional clinically necessary information beyond the stress test (e.g., to rule out acute myocardial infarction prior to performing the stress test).
