Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 62304 covers

A clinician places a needle into the lumbar subarachnoid space and injects contrast for myelographic imaging or CT of the spinal canal. Radiologists commonly perform the procedure in a hospital or outpatient imaging department when evaluation of lumbar narrowing, nerve-root compression, or postoperative anatomy calls for myelography. The code is specific to injection at the lumbar region; the extent of the imaging examination does not change the injection site selection.

Report 62304 when the documented procedure injects contrast at the lumbar level for myelography or CT, rather than a diagnostic spinal puncture without myelographic contrast. Documentation should identify the lumbar puncture, contrast injection, and imaging purpose. It has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.
