From knee braces and injectable drugs to trauma cases that move between surgeons, we code and bill orthopedic claims the way your practice actually works, not the way a generic template assumes.
DME & orthotic billing
Injectable drug (J-code) accuracy
Workers’ comp & no-fault claims
Transfer-of-care modifier support
A knee replacement or a rotator cuff repair is only one piece of what an orthopedic practice bills. The same patient chart can carry a prefabricated brace dispensed same day, a corticosteroid or viscosupplement injection given in the office, a course of post-op physical therapy run out of the practice, and a follow-up visit that falls inside someone else's global period because a hospital-based surgeon handled the original trauma call. Each of those has its own code set, its own medical necessity rules, and its own way of failing if it's coded in isolation.
The payer side adds another layer. A patient hurt at work or in a car accident isn't billed the same way as one covered by a commercial plan or Medicare Advantage: workers' compensation and no-fault auto carriers run their own fee schedules, their own utilization review process, and often their own claim forms entirely. A practice billing orthopedic claims well has to hold the clinical coding and the payer-specific rules together at the same time.
Most of these get caught before submission when someone is actually looking for them.
Drugs like triamcinolone (J3301) or hyaluronan-based viscosupplements (J7325) are billed by dosage unit, and the units on the claim have to match what the note documents. Missing the National Drug Code or rounding the unit count produces a rejection or a payment based on the wrong dose.
A prefabricated knee orthosis billed under a code like L1832 needs the KX modifier to confirm the medical necessity documentation is on file, laterality reported with RT or LT, and proof that the device was fitted and dispensed, not just ordered. Skip any one of those and the claim comes back.
The same procedure paid at an ambulatory surgery center reads differently to a payer than the identical procedure performed in a hospital outpatient department. When the site of service on the claim doesn't match the facility that actually rendered care, the facility fee and the professional fee can get denied separately.
These claims often use state-specific fee schedules and different authorization thresholds than commercial insurance. Billing them against a standard commercial fee schedule, or to the wrong claims address, is one of the more expensive mistakes because the appeal window is shorter.
When a trauma surgeon performs the surgery and the patient's regular orthopedist takes over post-op management, both sides of that split have to be reported correctly, one claim with modifier 54 for surgical care only and the other with modifier 55 for the post-operative management. Without both halves reported, one provider gets paid for work they didn't do and the other doesn't get paid at all.
Physical therapy delivered by the practice after surgery is sometimes billed as though it falls outside the global period when it doesn't, or bundled in when a separate, unrelated diagnosis should have kept it billable. Either direction shows up in an audit.
Orthopedic coding depends on matching the code to what was actually done and, just as often, to what was actually ordered and delivered. A brace code has to match the device dispensed, an injection code has to match the drug and the joint, and a fracture code has to match the fracture pattern documented in imaging.
Examples only. The correct code always depends on the documentation and the payer's local coverage policy.
Documentation should capture the specific diagnosis, anatomy, laterality, imaging findings, and the details needed to support the reported service.
Durable medical equipment carries its own coverage rules under Medicare's local coverage determinations. A knee orthosis or spinal orthosis has to match a covered diagnosis under the applicable policy, the device has to be verified against the PDAC product list, and the KX modifier confirms that supporting documentation is on file. Spinal cord stimulator trials typically need authorization before the trial and again before the permanent implant, and physical therapy delivered beyond the initial evaluation often needs separate authorization once visit limits are reached.
Trauma doesn't wait for a determination letter. A displaced fracture or an open injury gets treated the same day it presents, which means the authorization request has to be filed after the fact through a retrospective or expedited review pathway rather than before the procedure. Workers' compensation carriers run their own utilization review process on top of this, often on a different timeline than commercial pre-certification.
Getting the modifier right is often the difference between a DME or split-care claim paying in full and paying nothing at all.
Because orthopedic claims mix procedures, DME, and injectables in the same visit, we manage all three as one workflow rather than routing them to separate processes.
Benefits verification for both the medical claim and any workers' comp or no-fault coverage, DME order capture at the point of dispensing, and authorization requests filed before elective procedures and immediately after urgent ones.
Operative notes, drug administration records, and DME orders reviewed together, claims scrubbed against NCCI and MUE edits, and DME lines checked against the applicable local coverage policy before submission.
Denials worked with the documentation that actually supports them, whether that's an operative note, a local coverage policy, or a workers' comp fee schedule, appeals filed with payer-specific reasoning, and payments posted so underpayments get flagged and challenged.
Our coders and billers understand orthopedic-specific rules that help us serve orthopedic providers throughout the United States and adapt to your payer mix.
The same team codes the procedure, the brace, and the injection so nothing gets billed in isolation from the visit it belongs to.
Elective joint and spine procedures get authorization requested in advance. Trauma cases get the retrospective request filed the same week, not weeks later.
State fee schedules, separate claim addresses, and utilization review timelines are tracked without slowing down your commercial and Medicare claims.
Visibility into where DME, injectable, and surgical claims are getting held up, not just one blended AR number for the whole practice.
If DME denials, injectable drug rejections, or authorization delays on trauma cases are eating into revenue, we can walk through your current process and show you exactly where claims are stalling. Serving orthopedic providers across the United States.
