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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

62304 billing questions

How is 62304 distinguished from the other myelography injection codes?

Select 62304 for injection at the lumbar region. The cervical, thoracic, and combined-region codes reflect different injection sites or extent.

Is 62304 the same as a diagnostic lumbar puncture?

No. 62304 is for lumbar contrast injection for myelography or CT; 62328 describes a diagnostic lumbar spinal puncture with imaging guidance.

What documentation supports 62304?

Document the lumbar puncture site, intrathecal contrast administration, and the myelographic or CT examination being performed.

Should modifier 50 be appended for bilateral lumbar findings?

No. The CMS bilateral adjustment does not apply to 62304, and modifier 50 is inappropriate for this descriptor.

How does the multiple-procedure reduction affect 62304?

For procedures performed in the same session, CMS pays the highest-valued procedure in full and reduces the others to 50%.

Can an assistant or co-surgeon be reported for this procedure?

Assistant-at-surgery payment is statutorily restricted. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
