CPT code 62272 – Therapeutic spinal puncture for CSF drainage

Key takeaways

CPT code 62272 reports a therapeutic spinal puncture that drains cerebrospinal fluid by needle or catheter, and the code carries no imaging component.

A diagnostic lumbar puncture is 62270, so the purpose recorded in the procedure note decides between the two codes.

When fluoroscopy or CT guides the drainage, report 62329 instead, because that code already includes the imaging.

In 2026, Medicare’s national rate for 62272 is $217.85 non-facility and $85.26 facility at the qualifying APM conversion factor.

Pabau’s practice software submits claims through Claim.MD and tracks eligibility and ERA remittance, so your team can follow each 62272 claim to payment.

CPT code 62272: Official descriptor and clinical scope

CPT code 62272 describes a spinal puncture, therapeutic, for drainage of cerebrospinal fluid (by needle or catheter). The provider removes CSF from the subarachnoid space, usually at a lumbar level, to lower pressure or volume. The code describes the drainage alone. It has no imaging component, and its purpose is treatment rather than sampling.

The same needle technique can be diagnostic or therapeutic, and CPT gives each purpose its own code. Guidance with fluoroscopy or CT moves the service to a different code again.

62272 sits in the Surgery section of the CPT code set, under Nervous System. Within it, the code falls in the injection, drainage, or aspiration range for the spine and spinal cord (62263-62329). It is a standalone code with a 0-day global period. The American Medical Association’s CPT code set overview explains how the AMA maintains these descriptors.

What the procedure involves clinically

The patient lies in lateral decubitus or sits with the spine flexed. The provider identifies the interspace, usually L3-L4 or L4-L5, and enters the subarachnoid space with a spinal needle. Opening pressure is often measured before fluid is removed.

The provider then drains a planned volume of CSF and records the closing pressure where it was measured. Because the descriptor reads “by needle or catheter,” drainage through a catheter is reported with the same code. Some fluid may still go to the lab, but the documented reason for the puncture stays therapeutic.

CPT 62272 vs 62270, 62328 and 62329: Choosing the right lumbar puncture code

Two questions pick the code: was the puncture diagnostic or therapeutic, and did fluoroscopy or CT guide it? CPT 62270 is a diagnostic lumbar puncture without that guidance. CPT 62272 is a therapeutic drainage without it. Image-guided punctures move to 62328 and 62329, and those two codes include the imaging.

Work RVUs come from the CMS 2026 PFS relative value file, October release.

The practical rule is to read the indication first and the imaging second. A tap to relieve raised pressure in idiopathic intracranial hypertension is 62272 when no fluoroscopy or CT was used. The same drainage under fluoroscopy is 62329. A tap to look for meningitis is diagnostic, so it belongs to 62270 or 62328. The grid below puts both questions side by side.

What CPT code 62272 includes and excludes

62272 pays for the drainage itself. Knowing what sits inside the code, and what moves to another code, prevents both unbundling and the wrong-code denials that follow.

• Included in 62272: local anesthetic at the puncture site, needle or catheter placement, pressure measurement, CSF drainage and the post-procedure dressing.
• Not 62272: a drainage guided by fluoroscopy or CT. Report 62329 for that service, which already includes the imaging.
• One puncture, one code: do not report 62270 and 62272 for the same puncture. Choose the code that matches the documented purpose.
• Billed separately: laboratory analysis of any CSF specimens, which the lab reports under its own codes.

Sedation or general anesthesia from a separate anesthesia provider is not part of 62272 either. That provider reports the service with 00635.

Can you add an imaging guidance code to 62272?

When fluoroscopy or CT guides a therapeutic drainage, the correct code is 62329, not 62272 plus a guidance code. 62329 includes the imaging, so 77003 or 77012 is not added for that guidance. Check the current quarter’s NCCI edits before you combine 62272 with any other code on the same date.

ICD-10 codes commonly paired with CPT code 62272

Medical necessity for 62272 rests on a diagnosis that explains why CSF had to be removed. The strongest pairings are conditions where raised pressure or excess fluid is the problem being treated.

Codes and titles match the FY2026 ICD-10-CM code set from CMS. Obstructive hydrocephalus (G91.1) is left off the list on purpose. Lumbar drainage is generally avoided when CSF flow is blocked, so payers will question that pairing.

A vague code such as R51.9 (headache, unspecified) does not explain why fluid was drained. Link the specific condition that the drainage treats.

Documentation requirements for CPT code 62272

A clean 62272 claim starts with a procedure note that shows the drainage was therapeutic. If the note reads like a diagnostic tap, a payer can recode the claim to 62270 or deny it. Following clean claim requirements from the start removes most post-submission rework.

The procedure note should record these elements:

• Indication: the condition being treated and the reason drainage was needed.
• Purpose: a clear statement that the puncture was therapeutic.
• Positioning and level: lateral decubitus or seated, plus the interspace accessed.
• Technique: needle type and gauge, or the catheter used for drainage.
• Guidance: confirmation that no fluoroscopy or CT was used, since image-guided drainage is 62329.
• Pressures: opening and closing pressure in cmH2O where they were measured.
• Volume and appearance: the milliliters drained and the look of the fluid.
• Specimens and complications: any tubes sent to the lab, and any complication with the action taken.

Medicare reimbursement rate for CPT code 62272

Medicare pays 62272 at different rates in facility and non-facility settings, because the practice expense RVU changes with the setting. The figures below come from the CMS 2026 PFS relative value file, October release. For 2026, CMS set two conversion factors: $33.5675 for qualifying APM participants and $33.4009 for everyone else.

Each payment is the total RVU multiplied by the conversion factor, before the locality adjustment. Confirm your local rate in the CMS Physician Fee Schedule Look-Up Tool. Commercial rates are negotiated separately.

When the ERA remittance arrives, compare the paid amount against your locality rate to catch underpayments early.

Prior authorization and payer requirements for CPT code 62272

Prior authorization rules for 62272 depend on the payer, so check the patient’s plan before an elective drainage. Write that check into your billing compliance protocols so it happens at scheduling for every elective case.

• Traditional Medicare: prior authorization is not generally required for 62272.
• Medicare Advantage: requirements vary by plan, so verify with the plan before scheduling.
• Medicaid: requirements vary by state program.
• Commercial payers: policies vary, so confirm the rule for the specific plan and setting.
• What to send if authorization is needed: the order with 62272 specified, the clinical note showing the indication, and the ICD-10 code that supports drainage.

Urgent drainage, such as rapidly worsening vision in intracranial hypertension, often goes ahead before authorization. Record the urgency in the note and follow the plan’s retro-authorization process.

Common claim denial reasons for CPT code 62272

Denials on 62272 follow a predictable set of patterns. Each one has a front-end fix, and good denial management workflows apply it before the claim goes out.
