Medical Billing Services Group (MBSG) provides orthopedic billing services for practices losing revenue to bundled procedure edits, laterality errors, and global-period mistakes. We apply musculoskeletal NCCI policy, document injury phase and anatomic site, and manage surgical authorizations and implant documentation across office, ASC, and hospital settings.

Practice and setting fit
Orthopedic billing is difficult because the specialty combines high-dollar surgical cases with a long tail of office procedures, and the coding rules for each are unforgiving in different ways. Surgical cases carry global periods, bundled procedure edits, and bilateral reporting rules. Office procedures like injections, casting, and fracture follow-up carry their own bundling and medical-necessity edits, and groups operating in both an office and an ASC add place-of-service complexity.
We support independent orthopedic groups, sports medicine practices, hospital-based departments, and multi-site groups with in-office imaging or physical therapy. Claims need precise anatomic site, side, and injury phase to survive edits and medical-necessity reviews. A note that omits right versus left, or whether an encounter is initial, subsequent, or sequela, is a claim waiting to be denied. Our workflow catches those gaps before claims go out. See our specialty billing services hub for the other fields we cover.
Documentation and coding risks
For orthopedics, documentation quality is the revenue lever. ICD-10-CM FY2027 applies to encounters from October 1, 2026 through September 30, 2027, and musculoskeletal diagnoses demand exact anatomic site, laterality, and the seventh character for injury phase. Operative notes must support what was performed versus what was merely explored, because edits in this specialty frequently bundle an exploratory or diagnostic service into the definitive procedure.
Two sourced examples from NCCI musculoskeletal policy:
Sourced example: diagnostic arthroscopy is included in surgical arthroscopy
Under NCCI musculoskeletal policy, surgical arthroscopy includes the diagnostic arthroscopy, so the diagnostic service is not separately reportable. When a diagnostic arthroscopy at the same encounter leads to a surgical arthroscopy, only the surgical procedure is reported. Narrow exception: when the diagnostic work leads to the decision to perform an open procedure, it may be separately reportable with modifier 58, and the record must document its medical necessity.

Sourced example: arthroscopy converted to an open procedure
When an arthroscopic procedure converts to an open procedure, only the open procedure is reported. Neither a surgical nor a diagnostic arthroscopy code goes on the claim. The operative note’s conversion narrative directly determines the claim: if it does not clearly establish the conversion, billing cannot defend dropping the arthroscopy codes.

Beyond these examples, our medical coding services review catches the everyday orthopedic risks: injections billed for local anesthesia (not separately reportable under NCCI), casting and splinting absorbed into fracture care globals, and bilateral procedures reported without the correct modifier and unit conventions.

Payer and authorization checks
Medicare’s NCCI edits do not automatically apply to Medicaid or commercial payers. Commercial plans license their own edit sets, and state Medicaid programs adopt the Medicaid NCCI manual, which is why the examples above are labeled by program. Your billing must be checked against the edit set your actual payer uses.
Authorization is the other payer battleground. Surgical cases commonly require prior authorization naming the specific procedure and diagnosis, and authorized-versus-performed mismatches are a leading denial category. Implant claims need itemized documentation tied to the operative report, and workers’ compensation adds its own authorization and reporting requirements. We verify authorization against the operative plan before the case where possible, and reconcile authorized versus performed procedures after.
Workflow and reporting
Our workflow starts at scheduling: we confirm authorization for the planned procedure and flag documentation requirements for the note template. After the encounter, claims are scrubbed against the payer’s NCCI edit set for bundling, modifier use, laterality, and injury-phase coding. Denials route to our denial management team with operative documentation attached, because orthopedic appeals are won or lost on the note. An independent medical billing audit is available for one-time deep reviews.
Monthly reporting focuses on surgical revenue integrity. Illustrative report examples: denial rates by procedure category (arthroscopy, fracture care, injections, hardware), authorization-to-performed-procedure match rates, and aging segmented by office versus ASC versus hospital. These are illustrative examples, not guarantees. We also track implant reimbursement separately so you can see what hardware actually recovers versus what was billed.
Onboarding and pricing factors
Onboarding begins with a surgical documentation and authorization review: we sample operative notes, check your modifier usage, and map your payers to their edit sets. You provide EHR and clearinghouse access, payer contracts, and authorization workflows; we configure claim scrubbing for your procedure mix, set reporting cadence, and train your front desk on the authorization details that prevent denials.
Honest pricing factors for this specialty, with no invented rates:
- Pricing: surgical volume versus office volume affects how work is priced; we quote against your actual claim mix
- Minimum fees depend on monthly claim volume and provider count
- Turnaround: turnaround for claim submission and denial work is set in the agreement
- Staffing: team credentials are shared during scoping.
- all 50 states: service availability by state

FAQs and dated sources
Can we bill a diagnostic and a surgical arthroscopy for the same joint at the same encounter?
No. Under NCCI musculoskeletal policy, surgical arthroscopy includes the diagnostic arthroscopy, and only the surgical procedure is reported when the diagnostic work leads to it. (Source: 2025 Medicaid NCCI Coding Policy Manual, Chapter IV, Section E; revision effective January 1, 2025; last reviewed 2026-10-07.)
What happens when an arthroscopy converts to an open procedure?
Only the open procedure is reported; neither the surgical nor the diagnostic arthroscopy code is reported with it. The operative note should clearly establish the conversion. (Source: 2025 Medicaid NCCI Coding Policy Manual, Chapter IV, Section E; revision effective January 1, 2025; last reviewed 2026-10-07.)
Why do our claims keep denying for laterality?
Musculoskeletal claims require side-specific coding, and bilateral procedures have strict modifier and unit reporting conventions. Denials usually trace back to notes that omit side or coders that default to unspecified codes. (General coding principle applied to orthopedic claims; reviewed 2026-10-07.)
Do Medicare’s procedure edits apply to our commercial and Medicaid claims?
Not automatically. Commercial plans use their own edit sets and state Medicaid programs use the Medicaid NCCI manual. The examples on this page are labeled by program; each claim is scrubbed against the edit set of the payer on that claim. (General payer-policy principle; reviewed 2026-10-07.)
What diagnosis coding applies to our October 2026 encounters?
ICD-10-CM FY2027 applies to patient encounters from October 1, 2026 through September 30, 2027. Musculoskeletal encounters need exact site, laterality, and injury-phase characters. (Source: CMS “ICD-10” page, FY2027 files; verified 2026-10-07; effective October 1, 2026.)
