Summary & Overview
CPT 62273: Epidural Blood Patch for CSF Leak
CPT code 62273 denotes an epidural blood patch, a therapeutic procedure that injects a patient’s own blood into the epidural space to seal cerebrospinal fluid (CSF) leaks that cause post-spinal headaches. Nationally, this code is important because it represents a targeted intervention for a relatively common complication of neuraxial procedures — including epidural anesthesia, spinal needle placement, and lumbar puncture — and influences facility and physician billing for neuraxial complication management.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, the typical sites of service where the intervention is performed, and the common billing modifiers associated with the code. The publication summarizes what to expect in terms of coding classification and payer coverage patterns and highlights policy and documentation considerations that affect claim processing.
This overview provides clinicians, billers, and policy staff with operational clarity on when 62273 applies, how it fits into neuraxial complication care pathways, and the practical billing elements to verify when submitting claims to major national payers. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 62273 describes an epidural blood patch procedure in which a provider injects a patient’s own blood into the epidural space to seal a cerebrospinal fluid (CSF) leak. This service treats post-spinal headache that can occur after procedures such as epidural anesthesia, spinal needle placement, or lumbar puncture when a tear in the dura allows CSF to escape.
Service type: Procedure — therapeutic interventional pain management (epidural blood patch).
Typical site of service: Hospital outpatient department, inpatient setting, or ambulatory surgery center; procedure often performed where neuraxial procedures are managed and monitored.
Clinical & Coding Specifications
Clinical Context
A 34-year-old female presents 48 hours after an elective cesarean delivery with an obstetric epidural placed for labor analgesia. She reports a positional headache that is markedly worse when sitting or standing and improves when supine, accompanied by nausea and neck stiffness. Conservative measures including oral hydration, caffeine, and bed rest for 24–48 hours produced minimal relief. Neurology and anesthesia evaluate the patient and determine symptoms are consistent with a post‑dural puncture headache due to an inadvertent dural puncture during epidural placement. After informed consent, the anesthesia team performs an autologous epidural blood patch using sterile technique in an interventional suite or operating room. The patient is monitored for vital signs and neurologic status before and after the procedure and is discharged when symptoms improve and there are no complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the day of procedure | When an E/M visit is performed on the same date for evaluation prior to the blood patch and is distinct from the procedure itself |
59 | Distinct procedural service |
