About 62328: Image-guided diagnostic lumbar puncture
Reports a diagnostic lumbar puncture performed with fluoroscopic or CT guidance to obtain cerebrospinal fluid for laboratory analysis.
This service is a diagnostic lumbar puncture in which fluoroscopy or CT guides needle placement into the lumbar thecal sac to collect cerebrospinal fluid. Radiologists, including neuroradiologists, commonly perform it in a hospital imaging department or an outpatient imaging setting. A typical indication is obtaining CSF for laboratory evaluation when image guidance is needed, such as after a difficult or unsuccessful bedside attempt or when patient anatomy makes landmark-based access challenging.
Report the code when the purpose is diagnostic CSF collection and fluoroscopy or CT is used to guide the puncture. The record should identify the diagnostic purpose, imaging guidance, CSF collection, and relevant procedural details. Guidance is part of this service; distinguish it from a therapeutic puncture for CSF drainage and from lumbar access for myelography. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is statutorily restricted, and co-surgeon and team-surgery payment are not permitted.

62328 compared with similar codes
Office rates for Mississippi, from the same CMS release.
$243.30
The purpose separates the codes: 62328 obtains CSF for diagnosis, while 62329 drains CSF therapeutically under imaging guidance.
$220.25
Code 62302 is for myelography using intrathecal contrast, not diagnostic CSF collection. Do not select it solely because lumbar needle access is used.

62328 billing questions
When should this code be used instead of 62270?
Use this code for a diagnostic lumbar puncture performed with fluoroscopic or CT guidance. Code 62270 describes a diagnostic lumbar puncture without imaging guidance.
Can imaging guidance be billed separately?
Fluoroscopic or CT guidance is part of this service. Do not report a separate guidance service for the same puncture.
How does this differ from 62329?
This code is for diagnostic CSF collection. Code 62329 is for a guided spinal puncture performed to drain CSF therapeutically.
Is modifier 50 appropriate for bilateral punctures?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
Can an assistant or co-surgeon be paid for this service?
CMS applies a statutory restriction to assistant-at-surgery payment and does not permit co-surgeon or team-surgery payment for this code.
