What makes neurosurgery billing services different
Neurosurgery billing services are high-stakes surgical billing: five- and six-figure cases, near-universal prior authorization, 90-day global periods and coding rules that decide whether a decompression and a fusion on the same spine are one payment or two. Fastora provides neurosurgery medical billing for neurosurgery practices and spine centers, built around authorization packages that match the operative plan, decompression-versus-fusion coding, co-surgery and assistant modifiers, implant and hardware documentation, and global-period management. A neurosurgery billing company has to read operative reports the way coders read them — because the money is in the details.
The two failure points we see most are authorization letters that do not match the operative report, and NCCI bundling edits that eat the second procedure. Our medical billing services for neurosurgery are built to prevent both.
Spine coding: decompression, fusion and NCCI edits
| Procedure | Representative codes | Billing note |
|---|---|---|
| Lumbar laminotomy with discectomy | 63030 | Per interspace; additional levels have their own rules |
| Lumbar laminectomy with decompression | 63047 | Check NCCI pairing with fusion codes |
| Posterior lumbar interbody fusion | 22630 | Add-on technique code; needs a primary arthrodesis code |
| Posterolateral lumbar arthrodesis | 22612 | Primary fusion code; instrumentation reported separately |
| Anterior cervical discectomy and fusion | 22551 | Single-level; additional levels are add-ons |
| Craniotomy for supratentorial tumor excision | 61510 | Operative detail drives code selection |
Decompression and fusion at the same level on the same day are governed by NCCI edits — in many payer edits the decompression is bundled into the fusion, and unbundling requires documentation of a distinct, separately reportable service. We check every spine claim against the current NCCI edits before submission.
Our medical coding team codes neurosurgery claims from the operative report, not from the schedule — the schedule says what was planned, the report says what was done, and payers pay on the report.
Cranial procedure coding
Cranial cases — tumor resections, aneurysm clipping, shunt placements — are coded from the approach, the pathology and the structures addressed, and the operative note has to support each element. Approach codes, add-on codes for additional work and closure or reconstruction codes each need their own documentation.
We reconcile the operative report's documented approach, lesion description and closure to the code set before the claim is filed, since cranial claims that do not match the report are the ones auditors pull first.
Neuromodulation: trial and permanent implants
Spinal cord stimulators and other neuromodulation devices follow a trial-then-permanent pattern: trial lead placement, the permanent implant and the pulse generator each have their own codes and their own authorization. Payers typically require a documented successful trial before approving the permanent device.
We manage the authorization sequence — trial first, permanent after documented success — and keep the trial and permanent claims linked in the episode so the payer's own requirements are visibly met.
Prior authorization for every case
Nearly every elective neurosurgery case needs prior authorization, and the authorization must name the procedure, the level or levels and the approach. When the surgeon changes the plan in the OR — a one-level case becomes two, a decompression becomes a fusion — the claim has to be reconciled to what was authorized, and a retro-authorization or appeal prepared with the operative findings.
We build authorization packages from the clinical record against the payer's written spine-surgery policy, and we flag plan changes in the operative report the same day so nothing is billed against an authorization that no longer describes the case.
Global periods, co-surgery and assistant billing
Neurosurgery carries 90-day global periods, so related follow-up care is part of the package. Co-surgery is reported with modifier 62 when two surgeons of different specialties act as primary surgeons, and assistant-at-surgery with modifiers 80, 81 or AS — with Medicare restricting assistant payment for many codes.
We confirm each assistant and co-surgeon line against the payer's assistant-at-surgery policy before submission, because assistant denials on high-dollar cases are expensive to leave on the table and expensive to appeal late.
Implants, hardware and instrumentation
Instrumentation, cages, biologics and other hardware are documented with implant logs and, where payers require it, invoice or cost documentation for carve-out reimbursement. The implant documentation has to tie to the operative report's description of what was placed.
We reconcile implant logs to the operative report and to the claim before submission, so the hardware story is consistent everywhere the payer might look.
Common neurosurgery billing denials and how we prevent them
| Denial | Typical cause | Prevention step |
|---|---|---|
| Bundled second procedure | NCCI edit pairs decompression with fusion | Edits checked before submission; distinct service documented |
| Authorization mismatch | Operative plan changed in the OR | Operative report reconciled to authorization same day |
| Authorization denied | Conservative care not documented per policy | Authorization package built on payer's written policy |
| Assistant denied | Payer restricts assistant payment for the code | Assistant policy checked before submission |
| Global period conflict | Related E/M billed separately without modifier | Global-period calendar maintained per case |
Every claim passes our Advanced Pre-Submission Claim Review before submission. Denials that still occur are worked by our denial management team, corrected and resubmitted or appealed with the record, and open balances are followed up by payer and age.
Credentialing for neurosurgery practices
Neurosurgeons, physician assistants and nurse practitioners each need enrollment with the plans the practice bills, and hospital-based practices need the facility relationships and privileges documented so professional and facility claims align.
Our credentialing and enrollment service tracks each file through a nine-stage process, from document collection and NPI and CAQH setup to payer applications, follow-ups and final approval.
