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.
For patients post-heart transplant without evidence of rejection, use primary diagnosis Z09 (follow-up after completed treatment) and secondary diagnosis Z94.1 (heart transplant status); add the underlying disorder code when coding I25.82 or I31.4.

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).
Coverage indications for Coronary Computed Tomography Angiography (CCTA) are defined in the associated Local Coverage Determination LCD L35121; consult LCD L35121 for specific clinical criteria and medical necessity requirements.
CCTA may be used to reliably rule out significant coronary artery disease (CAD) in patients with low to intermediate pre-test probability of CAD as an alternative to an imaging stress test.
CCTA may be used in a patient presenting with chest pain syndrome when the clinician has a high degree of suspicion that CAD is high on the differential diagnosis.
