Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
- Billing and coding guidance in this policy complements and references Local Coverage Determination L34425; claims should be supported per the documentation requirements specified in LCD L34425.
- Medical record documentation must demonstrate clinical evidence of an intracranial disorder or documentation of an established intracranial disease to support coverage of cranial CT.
- When contrast-enhanced CT is ordered for staging, documentation must record the known primary cancer (e.g., lung cancer, breast cancer, lymphoma) and clinical rationale for brain staging.
Key Coverage Criteria
- No specific clinical indications are listed in this billing/coding guidance; coverage determinations for MRI of the head and neck follow Local Coverage Determination L34425.
- Cranial CT (with or without contrast) is covered when the patient has clinical evidence of an intracranial disorder or an established intracranial disorder/disease.
- Contrast-enhanced CT is reasonable and necessary to assess cerebral perfusion, for example in suspected or known cerebrovascular accident (CVA).
- Contrast-enhanced CT is covered to characterize a specific intracranial lesion.
- Contrast-enhanced CT is covered to detect blood–brain barrier defects such as infarcts, tumors, infection, or vasculitis.
- Contrast-enhanced CT is covered to detect neovascularity associated with intracranial tumors.
