Specialty billing
Orthopedics Medical Billing Services
Orthopedic billing centers on surgical global periods, multiple-procedure reduction rules, and the split between surgical and conservative care. Because orthopedic procedures carry high per-claim values, a single systematic error — an unbundled arthroscopy component or a mishandled global period — has outsized revenue impact.

The complexity
Why orthopedics is uniquely difficult to bill
Surgical procedures carry 10- or 90-day global periods bundling related follow-up
Multiple procedure reduction applies sequenced payment cuts to additional procedures
Arthroscopy codes bundle extensively — unbundling triggers NCCI denials and audit risk
Fracture care may be billed globally or itemized, and the choice is not reversible
Bilateral procedures require modifier 50 and payer-specific unit conventions
In-office DME dispensing carries its own HCPCS coding and documentation rules
Coding
Orthopedics procedure codes we work with daily
A representative sample, not an exhaustive list. Coders are assigned by specialty rather than pooled.
| Code | Description |
|---|---|
| 29881 | Knee arthroscopy with medial or lateral meniscectomy |
| 27447 | Total knee arthroplasty |
| 20610 | Arthrocentesis or injection, major joint or bursa |
| 29827 | Shoulder arthroscopy with rotator cuff repair |
| 27130 | Total hip arthroplasty |
| 73721 | MRI, lower extremity joint, without contrast |
Revenue leakage
Where orthopedics practices lose money
These are the denial patterns specific to this specialty — the ones a general-purpose billing service will not be looking for.
Global period violations
Post-operative visits billed separately within the global period without modifier 24, or unrelated procedures without modifier 79.
Arthroscopy unbundling
Component procedures billed alongside a comprehensive arthroscopy code that already includes them under NCCI edits.
Missing prior authorization
Elective joint replacement and advanced imaging denied because authorization was not obtained or not documented on the claim.
Modifier 50 conventions
Bilateral procedures billed as two lines where the payer requires one line with modifier 50, or vice versa.
Conservative care requirements
Surgical authorization denied because the payer requires documented failure of conservative treatment over a defined period.
Payer landscape
What orthopedic practices need to know about payers
Payer policy drives more orthopedics denials than coding does. Knowing the policy before the service is what prevents them.
- Most commercial payers require documented conservative treatment before authorizing elective joint replacement, typically six weeks to three months.
- Multiple procedure reduction is standard at 100/50/50 but several payers apply steeper reductions on the third and subsequent procedures.
- Workers' compensation and personal injury claims follow entirely separate fee schedules and authorization pathways.
Proof
A orthopedics practice we worked with
Pacific Orthopedics recovers $150K in denied claims
Surgical coding complexity had produced a 35% denial rate on orthopedic procedures. The previous billing company had limited orthopedic expertise, resulting in systematic undercoding and a backlog of denied surgical claims nobody had appealed.
We assigned certified orthopedic coders, implemented comprehensive procedure documentation review, and launched an appeal process covering every rejected surgical claim still inside its filing window.
Results
- Denial rate decreased from 35% to 9%
- $150,000 recovered in previously denied surgical claims
- Surgical reimbursement rates increased 28%
- Documentation improvements reduced ongoing compliance risk

Questions
Orthopedics billing FAQ
Last updated August 20, 2026
Reviewed by a certified coding leadMajor orthopedic procedures carry a 90-day global period; minor procedures carry 10 days. Routine post-operative care within that window is included in the surgical payment and not separately billable. Unrelated care during the period is billable with modifier 24, and a related return to the operating room uses modifier 78.
Comprehensive arthroscopy codes already include debridement, synovectomy and related work in the same compartment. NCCI edits reject the component codes when billed alongside. Billing separately for work in a genuinely different compartment is legitimate, but it requires documentation of the distinct compartment to survive review.
It depends on whether you will provide the full course of care. Global fracture care covers the initial treatment and all follow-up within the global period. If the patient will follow up elsewhere, itemized billing is more appropriate. The choice must be made at initial billing and is difficult to unwind afterward.
Yes. Both operate outside standard commercial billing — separate fee schedules, separate authorization requirements, and in personal injury cases, letters of protection with settlement-contingent payment timelines. They need to be tracked separately from your commercial AR.
