- Medical records must include history and physical notes, laboratory results, and documentation of signs and symptoms that warrant the head/neck diagnostic imaging.
Key Coverage Criteria
- Therapeutic procedures whose principal aim is to treat a respiratory impairment must be billed using HCPCS codes G0237, G0238, or G0239.
- CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
- Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
- Initial lumbar MRI is covered when the test is medically reasonable and necessary and the medical record documents clinical rationale and supports the ICD-10-CM code(s) billed.
- A second lumbar MRI for the same patient is allowable when documentation shows comparative test results are needed to make a more definitive treatment decision.
- Multiple scans of different body areas performed on the same day for the same patient are payable when each scan is reasonable and necessary.
