ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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.
