CPT code 61582: Craniofacial approach, skull base surgery2026 Medicare rate & RVUs

Medicare pays $3,077.56 for 61582 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 61582 covers

This code represents a craniofacial approach to the skull base, combining facial and cranial exposure to reach a lesion involving the anterior cranial fossa. A neurosurgeon may work with an otolaryngologist or a facial plastic surgeon when a tumor, such as an anterior skull base malignancy, requires access from both sides of the skull base. The service is generally performed in a hospital operating room and involves substantially more than a routine craniotomy or an isolated sinonasal tumor removal.

Report 61582 when the operative report supports the specific approach and work described by this code; use the complete code descriptor to distinguish it from related craniofacial approach codes. Documentation should identify the lesion, route of access, intracranial work, and surgeons’ roles. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is permitted.

How to choose

61580Craniofacial approachExtradural anterior fossa

Both describe craniofacial skull approaches. Select between them using the full descriptors and the approach and operative work documented in the report.

61581Craniofacial approachAnterior cranial fossa

This is a sibling craniofacial approach code. The operative report must support the specific variant represented by the selected code.

61583Craniofacial approachMiddle fossa, intradural

This is another craniofacial approach code; distinguish it from 61582 by matching the complete descriptor to the documented operative configuration.

61584Skull base approachExtradural, orbital osteotomy

61584 describes an orbitocranial route. Use 61582 when the documented approach matches its craniofacial skull-base work instead.

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.
