Medical Billing Software for Orthopedic Billing Companies

Short answer

Orthopedic billing turns on the global surgical package: it bundles pre-operative, intra-operative, and post-operative care into one payment, and every surgical claim carries a global period of 0, 10, or 90 days under CMS rules. Services inside that window are either included in the global payment or carry a modifier to be separately payable, and a missed modifier loses the payment. Orthopedic claims also stack surgical, bilateral, laterality, and assistant-at-surgery modifiers with fracture care supply codes in combinations that vary by payer, place of service, and procedure. Prior authorization concentrates on elective surgeries and advanced imaging. A billing company running orthopedic practices needs software that shows denials at the service-line level with CARC and RARC in plain English, keeps auth status linked to claims, and posts ERA at the line level. See the CMS Global Surgery booklet (MLN907166) and the CMS NCCI policy manual.

Why orthopedic billing is different

Two structural features make orthopedic revenue cycle harder to run at scale than most specialties.

The first is the global surgical package. CMS defines it as the pre-operative visit on the day before or day of surgery, all intra-operative services, complications not requiring a return to the operating room, post-operative office visits within the global period, and miscellaneous services including suture removal and dressing changes. For a 90-day procedure, that window runs from the day of surgery through 90 days after. E/M visits, injections, and additional procedures inside that window are either bundled or need a specific modifier to pay separately, and a high-surgical-volume practice triggers this on every operative claim.

The second is modifier density. A bilateral procedure with a physician assistant, staged with a prior surgery, billed the same day as an unrelated E/M visit can carry modifiers 50, 58, 80, and 25 on one claim. Each modifier has its own documentation requirement, payment arithmetic, and payer-by-payer variation. A missed modifier loses the payment; a wrong one generates a denial to work or an overpayment that gets recouped later.

Fracture care runs on a parallel track. Casting, splinting, and supply codes sit alongside professional fracture management codes, with DMEPOS L-code braces billed under separate Medicare DMEPOS enrollment. Joint injections and DMEPOS orthotics supplied to the same patient on the same date create combinations that need clean separation to avoid bundling denials.

The global surgical package: what is bundled and what is not

CMS assigns a global period indicator to every surgical procedure in the Medicare Physician Fee Schedule. Most major orthopedic surgeries, including joint replacements, rotator cuff repairs, and spine procedures, carry a 90-day global period. Many minor procedures, including joint injections and minor wound debridements, carry a 10-day period. A 0-day period means the day of surgery is the only bundled day.

Bundled into the global package during the global period: post-operative office visits related to the surgery, simple suture removal, dressing changes, and the surgeon's care for complications that do not require a return to the operating room.

Not bundled, and therefore separately payable with the right modifier:

• An E/M visit on the day of a minor procedure when a separately identifiable service was performed that was not part of the pre-operative assessment (modifier 25)
• An E/M visit on the day before or day of a major procedure that drove the decision to operate (modifier 57)
• A procedure during the global period that was planned prospectively as a staged step of the original surgery (modifier 58)
• An unrelated procedure during the global period by the same surgeon (modifier 79)
• A return to the operating room for complications during the global period (modifier 78)
• An E/M visit during the global period for a condition completely unrelated to the surgery (modifier 24)
• A procedure during the global period at a separate anatomical site from the original surgery (modifier 59, or the appropriate X-subset modifier)

Modifier 58 resets the global period clock. A staged procedure billed with modifier 58 starts a new global period for that second procedure. Modifier 79 also starts a new global period. Modifier 78 does not start a new global period. These distinctions affect how subsequent visits in the same episode should be billed.

Surgical and laterality modifiers

Orthopedic claims use a concentrated set of modifiers that interact with each other and with CMS payment rules. These are the ones that generate the most claim errors.

Fracture care coding: professional services and supplies

Fracture care billing runs on two parallel tracks that must stay cleanly separated on the claim.

The professional service track covers fracture management CPT codes that include the treatment, initial cast or splint application, and normal follow-up within the fracture care global period. A biller needs to know whether the fracture care CPT bundles supply codes or leaves them separately reportable. Minor closed fracture management codes typically bundle the initial casting or splinting; additional re-casting visits are billed separately. Open or percutaneous fracture procedures with internal fixation carry 90-day global periods, so post-operative care is bundled.

The supply track covers Q-codes and L-codes:

• Q-codes (HCPCS Level II) report cast and splint supplies when they are separately billable alongside fracture management professional services. These are for the materials themselves, not the application service.
• L-codes (HCPCS Level II) cover orthotics and braces. An orthopedic practice that provides a knee brace or walking boot at the time of service bills an L-code for the device. Examples frequently seen in orthopedic practices include codes in the L1000-L4999 range covering ankle-foot orthoses, knee orthoses, and spinal orthoses.

The DMEPOS separation matters. A practice that provides DME or orthotics and bills L-codes to Medicare needs a separate DMEPOS number on top of its standard NPI and PTAN. In traditional Medicare, the professional service and the DMEPOS supply are paid by different contractors, so one claim cannot carry both and expect both to pay through a single MAC. For practices with in-office orthotics dispensing, confirm DMEPOS enrollment before the first L-code goes out: billing L-codes without enrollment produces denials that are not recoverable retroactively.

Joint injections, aspiration, or viscosupplementation injections billed on the same date as fracture care or a post-operative visit can create bundling conflicts. If the injection site is unrelated to the surgical or fracture site and is separately documented, modifier 59 or the appropriate X-subset may apply. If there is any overlap with the global period for an active surgery episode, modifier 24 and a separate diagnosis are required.

Prior authorization: surgeries and advanced imaging

Prior authorization in orthopedics does not reach the per-procedure volume that interventional pain does, but it concentrates in the highest-revenue claims. Elective joint replacements, spine surgeries, and rotator cuff repairs almost universally require authorization from commercial payers and Medicare Advantage plans. Advanced imaging, particularly MRI for soft tissue or spine pathology, frequently requires authorization before the scan.

The billing risk is specific: the surgery happens and the auth number was issued, but it covered the wrong procedure code, the wrong date range, or a different surgeon than the one who performed the case. Those mismatches produce auth-related denials in adjudication that are hard to cure retroactively, and some payers require a fresh authorization request before they reconsider the claim.

Across multiple practices, the hard part is not any single auth request, it is visibility across all of them. Authorization status needs to sit at the claim level so billers can confirm an auth number is attached, current, and matched to the procedure before the claim goes out.

Denial patterns orthopedic billing companies see most

**Global period denials** are the defining failure mode. A post-operative E/M visit, follow-up injection, or wound check that should carry modifier 24 but goes out without it is automatically denied as bundled into the global. At scale, across ten practices with several surgeons each, that is a meaningful revenue gap.

**Missing or wrong surgical modifiers** come next. Bilateral procedures submitted without modifier 50 pay at the single-procedure rate. A bilateral knee procedure billed as RT and LT on two lines, rather than the single-line modifier 50 format Medicare expects, often generates a second-line denial or a duplicate edit. An assistant surgeon billing modifier 80 on a procedure the MPFS database codes "assistant at surgery not paid" (indicator 2) gets a flat denial regardless of documentation.

**Staged procedure errors** happen when a surgeon performs a second related procedure, such as hardware removal after fracture fixation, during the original global period, and the biller omits modifier 58. The payer bundles it and pays nothing for what was a legitimate staged service.

**NCCI bundling hits** land most often when injections, imaging, or supply codes that are component parts of a comprehensive surgical CPT are separately reported on the same claim. Modifier 59 and X-subsets can overcome some NCCI PTP edits, but only when documentation genuinely supports a distinct service at a separate site or session.

**Auth-related denials** cluster on elective surgeries and advanced imaging: the claim is technically correct but the authorization number is missing, carries the wrong CPT code, or expired before the service date.

**DMEPOS enrollment gaps** produce denials when a practice bills L-codes for braces or orthotics without the required DMEPOS supplier number.

**Medical necessity denials** appear most on spinal fusion, joint replacements, and advanced imaging, where payers apply conservative-care-first criteria or require documented failure of specific conservative treatments before authorizing the procedure.

How Medi handles orthopedic billing-company workflows

Medi is a billing-company-first RCM operating layer. It does not auto-code or generate clinical documentation, and it does not replace billers. It organizes the work billers already do across multiple orthopedic practices in one place.

**Denial management.** Medi surfaces the CARC and RARC on each service line in plain English. A global period denial with CARC 97 on a bundled post-operative visit calls for different action than a CARC 4 auth denial or a CARC 133 bilateral-procedure adjustment. Billers see the denial reason at the line level, with status tracking, notes, and routing, instead of toggling between remittance files and spreadsheets. The queue is organized per line, per claim, per practice. See the denial management workflow guide.

**Global period visibility.** Claims sit in a per-practice work queue where billers see open claims, denial status, and ERA-matched payment together. A surgical claim with active global period lines and a subsequent E/M visit can be reviewed in one interface, no cross-referencing. Medi does not flag global period conflicts or suggest modifiers; that judgment stays with your billers.

**Auth status tracking.** Medi surfaces authorization status at the claim level. Billers attach an auth number, see which claims are waiting on authorization, and route auth denials into a separate follow-up queue. Medi does not submit authorization requests; that still runs through payer portals, the practice EHR, or a dedicated prior-auth platform.

**ERA and 835 review.** Medi imports ERA files through Stedi and presents payment at the service-line level. A surgical claim paid at the bilateral adjustment rate, with a separately adjudicated assistant surgeon line, shows both adjustments next to the original billed and paid amounts. Billers review each line's adjustments, flag underpayments, and route to follow-up.

**Practice and provider permissions.** Medi supports practice-scoped and provider-scoped access. A billing company with ten orthopedic practices can assign billers to specific practices without exposing the full book, while operations leads see across all practices from one view.

What Medi does not do: generate CPT or ICD-10 codes, auto-apply global period modifiers, ship orthopedic-specific claim edits, validate NCCI PTP edits before submission, or submit prior authorization requests. Those decisions stay with your billers and your clearinghouse. See the billing company software evaluation guide, or schedule a demo.

When Medi is not the right fit

Medi is the wrong choice if you need orthopedic coding assistance or charge review against global period and NCCI criteria. That work needs a coder with orthopedic experience or a coding-focused integration, and Medi does not fill it.

If your practices run on a single EHR with a strong built-in billing module and one shared clearinghouse, with no multi-practice coordination need, a second workflow layer may not earn its place.

If your core problem is clinical documentation quality for medical necessity denials on spine and joint replacement, or you need a system that builds the prior authorization packet from clinical notes, Medi does not do that. A utilization management or prior-auth platform covers that layer.

If your practices run in-house DMEPOS operations at high brace and orthotics volume and need supplier inventory, billing, and audit documentation in one place, a DMEPOS-specialized platform fits better than a general RCM tool.

Frequently asked questions

How does the 90-day global surgical period affect daily billing work in an orthopedic practice?

Every post-operative visit, injection, or additional procedure within 90 days of a major surgery must be evaluated against the global package before the claim goes out. If the service is related to the surgery, it is either bundled and not separately billable or needs a modifier such as 78 for complications or 58 for a staged planned procedure. If it is unrelated, modifier 24 (for an E/M) or 79 (for a procedure) allows separate billing, but documentation must make the unrelated nature clear. For high-surgical-volume practices, this runs on a large share of daily encounters and is one of the most time-intensive parts of the specialty.

When does an orthopedic E/M on the day of surgery need modifier 25 versus modifier 57?

Modifier 25 applies when a significant, separately identifiable E/M is performed the same day as a minor procedure with a 0-day or 10-day global period, and the E/M went beyond the standard pre-procedure assessment. Modifier 57 applies when an E/M on the day before or day of surgery led directly to the decision to perform a major procedure with a 90-day global period. The distinction matters: modifier 57 belongs on the E/M for major surgery decisions, and using modifier 25 there generates a claim error. In both cases, documentation must show the E/M was a distinct, medically necessary service beyond routine pre-operative evaluation.

What is the Medicare payment rule for bilateral orthopedic procedures using modifier 50?

Under the Medicare Physician Fee Schedule, a procedure reported with modifier 50 is paid at 150 percent of the single-procedure amount when the MPFS database designates it bilateral. Indicator 1 means bilateral payment applies at 150 percent when modifier 50 is appended. Indicator 3 means the procedure is inherently bilateral and pays at 100 percent regardless of modifier 50. Indicator 2 means it is not paid separately as bilateral under any circumstance. Do not combine LT or RT with modifier 50 on the same line. Confirm the bilateral payment indicator for each procedure in the MPFS Look-Up Tool before applying modifier 50.

When must an orthopedic practice have a DMEPOS supplier number to bill braces and orthotics?

Any orthopedic practice billing L-codes for orthotics or braces to Medicare must have a separate DMEPOS supplier number from the National Supplier Clearinghouse, on top of its standard NPI and PTAN. Without it, L-code claims submitted to the Part B MAC deny. This covers prefabricated orthoses dispensed in the office and custom fabricated devices. Commercial payers vary, but Medicare's rule is a hard threshold. When onboarding a new orthopedic practice, confirm DMEPOS enrollment before the first L-code claim goes out.

Does Medi validate global period conflicts or apply modifiers automatically?

No. Medi does not detect global period conflicts, suggest modifiers, or auto-correct coding before submission. That judgment needs a biller who knows the surgery history, payer policy, and clinical documentation, which Medi does not access. What Medi does is surface denials with CARC and RARC translations at the service-line level: when a global period denial arrives on a post-operative claim, the biller sees the reason in plain English and acts on it with the right modifier and appeal documentation, instead of hunting through remittance files to find it.

What is the difference between modifier 78 and modifier 58 for a second orthopedic surgery during the global period?

Modifier 78 applies when the patient returns to the operating room to treat a complication of the original surgery during the active global period. The second procedure is paid at the intra-operative component only, and the original global period continues. Modifier 58 applies when the second procedure was planned prospectively at the time of the original surgery as a staged step in the treatment plan; the staging intent should be documented in the operative note or plan at the time of the first procedure, not asserted after the fact. Modifier 58 starts a new global period for the staged procedure and pays at the full fee schedule amount for that code.
