What 62284 covers

This service covers placing a spinal needle and injecting contrast into the spinal canal for a myelographic examination or CT performed after intrathecal contrast. A radiologist, neuroradiologist, or other qualified physician typically performs it in a hospital or imaging center. The injection supports evaluation of the spinal canal, nerve roots, or related structures when myelography is requested.

Report 62284 for the contrast injection procedure, with documentation identifying the indication, spinal access, contrast administration, and related imaging examination. Report the applicable myelographic imaging service separately when performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery and does not permit co-surgeons or team surgery for this service.

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.

62284 billing questions

How is 62284 different from a diagnostic lumbar puncture?

62284 reports spinal access with contrast injection for myelography or CT myelography. A diagnostic lumbar puncture such as 62270 is for obtaining cerebrospinal fluid, rather than injecting contrast for imaging.

Can the myelographic imaging be reported separately?

Yes. Report the applicable imaging service, such as cervical or lumbosacral myelography, separately when performed; 62284 describes the injection procedure.

Should modifier 50 be appended for injections on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does the multiple-procedure reduction affect 62284?

When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and reduces the other procedures to 50%.

Are assistant or co-surgeon claims payable?

CMS does not pay an assistant at surgery for 62284 and does not permit co-surgeons or team surgery.

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.
