Summary & Overview
CPT 62272: Lumbar Puncture (Spinal Tap) to Withdraw CSF
CPT code 62272 denotes a lumbar puncture (spinal tap) performed to reduce cerebrospinal fluid (CSF) pressure by inserting a needle or catheter into the subarachnoid space and withdrawing CSF. Nationally, this procedure is a critical diagnostic and therapeutic intervention for conditions such as suspected meningitis, subarachnoid hemorrhage evaluation, and management of elevated intracranial pressure. Accurate coding for 62272 matters for clinical documentation, hospital workflow, and appropriate payment for a time-sensitive procedure.
Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides comparative benchmarks where available and summarizes common clinical contexts and coding considerations relevant across major national payers.
Readers will find a concise clinical context for the procedure, typical sites of service, and the scope of services represented by 62272. The piece outlines typical documentation elements needed to support the code, common modifiers in use, and how 62272 fits into procedure-driven service lines. The analysis highlights national policy and billing considerations that affect reimbursement consistency and administrative processing. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 62272 describes a procedure to reduce cerebrospinal fluid (CSF) pressure on the brain by inserting a hollow needle or catheter into the subarachnoid space, most often in the lower back, to withdraw CSF. This procedure is commonly known as a spinal tap.
Service Type: Diagnostic and therapeutic lumbar puncture / CSF drainage
Typical Site of Service: Hospital inpatient or outpatient setting, emergency department, or ambulatory surgical center — procedure performed at the lower back (lumbar) spine in a sterile procedure area.
Clinical & Coding Specifications
Clinical Context
A 34-year-old patient presents to the hospital emergency department with a 3-day history of progressive severe headache, fever, neck stiffness, and photophobia. Neurologic examination suggests meningeal irritation and the provider suspects acute bacterial meningitis. After initial stabilization, laboratory testing, and neuroimaging (to exclude mass lesion), the neurology team performs a diagnostic and therapeutic lumbar puncture to measure opening pressure, obtain cerebrospinal fluid (CSF) for cell count, glucose, protein, Gram stain and culture, and partially relieve elevated intracranial pressure.
The clinical workflow: the patient is consented; coagulation status is reviewed; the patient is positioned in lateral decubitus or sitting position; the procedure area is prepped and draped; local anesthetic is administered; a spinal needle or introducer and catheter are inserted into the subarachnoid space; opening pressure measured with manometer; CSF collected in sterile tubes; needle withdrawn and a sterile dressing applied. Documentation includes indication, site, patient position, opening pressure, CSF findings, any complications (e.g., headache, bleeding), and use of imaging or anesthesia. Billing uses 62272 for therapeutic or diagnostic lumbar puncture/spinal tap when performed.
