How are orthopedic surgical procedures billed with global periods?

Most orthopedic surgical procedures include a global surgical period (typically 90 days for major surgeries, 10 days for minor surgeries). During this period, routine post-operative care is included in the surgical fee and should not be billed separately. However, services for unrelated conditions, complications requiring a return to the operating room, and diagnostic services unrelated to the surgery can be billed with the appropriate modifiers - one flagging an unrelated office visit during the recovery period, one flagging a return to the operating room for a related complication, and one flagging an unrelated procedure.

What makes orthopedic billing complex?

Orthopedic billing complexity stems from: (1) High surgical volume - joint replacements, arthroscopy, fracture repair, and spine surgery are high-value cases that need precise coding, (2) Global surgical periods - most orthopedic procedures carry 90-day global periods during which post-operative care is bundled, (3) Fracture care coding - fracture care is divided into initial treatment (with or without manipulation), type of fracture fixation (closed vs open reduction), and follow-up within the global period, (4) Multiple procedure coding - bilateral joint replacements, multi-level spine surgery, and combined arthroscopic procedures require careful use of bilateral, multiple-procedure and distinct-service flags, (5) Implants - prosthetic joints, fixation hardware, and bone substitutes need documentation that matches how they are billed in each setting, and (6) Workers compensation - orthopedic practices see significant workers comp volume with different fee schedules and authorization requirements.

What are common authorization requirements for orthopedic procedures?

Common orthopedic procedures requiring prior authorization include: (1) MRI, CT scans, and advanced imaging; (2) Joint replacement surgeries (hip, knee, shoulder); (3) Arthroscopic procedures; (4) Spinal surgeries (fusion, decompression, disc replacement); (5) DME such as braces, orthotics, and wheelchairs; (6) Physical therapy beyond initial visits; (7) Injections (joint, epidural steroid, viscosupplementation); (8) Outpatient vs. inpatient status for surgical procedures. Authorization requirements vary by payer and plan, so always verify before scheduling procedures.

How are fracture care services coded in orthopedics?

Fracture care billing turns on the treatment approach, and mixing up the categories either underpays the practice or triggers a denial. There are three levels: closed treatment without manipulation, closed treatment with manipulation (which pays more for the same site), and open treatment with internal fixation, which is surgical and carries a 90-day global period. The initial cast or splint is included in the fracture-care service, so it is not billed on its own; later cast changes are billed separately. Follow-up visits during the global period are already included unless you are addressing a genuinely separate problem, in which case the visit is flagged as unrelated to the surgery so it is paid. Multiple fractures are each billed individually. When you interpret the imaging yourself, the professional (interpretation) component of the X-ray is billed separately from the fracture care.

What are common orthopedic billing denials?

Top orthopedic denials: **Prior Authorization:** Joint replacement, spine surgery, and arthroscopy denied without pre-authorization and documented conservative treatment failure (PT, injections, medications for 6+ weeks). **Global Period Violations:** Post-operative visits billed during the 90-day global period without documentation that they were unrelated to the surgery. **Bilateral Errors:** Bilateral procedures not flagged as bilateral, or billed with incorrect flag combinations. **Fracture Care Overlap:** Billing both emergency-department fracture management and the surgeon's definitive fracture care - the surgeon's global fracture care already includes the initial treatment. **Implant Documentation:** Hardware and prosthetic charges denied without operative-note documentation of the specific implant type, size, and manufacturer. **Workers Comp Authorization:** Treatment beyond the initial visit denied without utilization-review approval in states that require treatment-guideline compliance.

Orthopedic Billing - Stop Losing Surgical Revenue

Billing for orthopedic practices: surgical procedures, implants and the post-op care period. Our coders know fracture care, arthroscopy rules and workers' compensation claims.

The 90-day post-op period after most orthopedic surgery bundles routine follow-up into the surgical fee - but legitimate separate care during that window is billable revenue most practices leave behind.

When your surgeons perform more than one procedure in a session, insurers pay the extra procedures at a reduced rate, so how the claim is built decides how much of it you actually keep.

Joint replacements, fracture repair, and the implants they require are among your highest-value claims, where small billing gaps become large dollar losses.

How We Fix Orthopedic Reimbursement

Each fix below answers one of the problems above.

Step 01

Surgeons Paid in Full for Every Procedure

We bill joint replacements, arthroscopy, fracture repair and spine cases for everything your surgeons actually did - not just the headline procedure.

Every procedure in a session captured, not collapsed into one / Follow-up care during the post-op window billed when it's legitimately separate / Complex and revision cases reimbursed at their true value / Fewer denials sent back, faster payment on the ones that go out

Step 02

Full Recovery on Implants and Hardware

Plates, screws, prosthetics, and other implants are among your biggest per-case costs. We make sure the price of that hardware is documented and claimed so it comes back to the practice instead of coming out of your margin.

Implant and hardware costs billed as their own line, not absorbed / Documentation handled so device claims survive payer audits / Vendor and invoice detail tracked case by case / Margin protected on high-cost surgical supplies

Step 03

Post-Op Follow-Up Revenue You're Currently Missing

We track the post-op window on every surgical patient and flag the visits and procedures that fall outside the bundled package - so legitimate follow-up work gets paid instead of being written off out of caution.

We track the post-op window on every surgical patient / Separately billable follow-up flagged before it's written off / Clean line between bundled and billable care to avoid audit exposure / Recovered revenue that most practices leave on the table

Step 04

Getting Surgeons Paid on Workers' Comp Cases

Orthopedic surgery drives comp claims, and comp plays by its own rules. We handle surgical pre-authorization, comp fee schedules and liens, and disputed claims so your surgeons actually collect on work-injury cases instead of chasing them.

Surgical pre-authorization secured before the comp case reaches the OR / Independent medical exams and impairment-rating reports billed as the physician services they are / Comp fee schedules and liens managed to protect the surgeon's payment / Disputed and delayed comp surgical claims pursued to collection

Common Revenue Leaks in Orthopedic Billing

Orthopedic practices face unique billing complexities with surgical post-op periods, high-cost implants, and procedure-specific bundling rules that can significantly impact revenue and reimbursement.

Billing During the 90-Day Global Period Is Where Orthopedic Revenue Gets Lost

Orthopedic surgeries carry 90-day global periods that bundle most related services into the surgical fee. Without careful tracking of what's genuinely separate, legitimate follow-up work goes unbilled or triggers a denial.

Impact: Lost revenue from incorrectly billing services during post-op periods

Fracture Follow-Ups Billed the Wrong Way Get Bundled Away or Rejected

Fracture treatment bundles initial care, follow-ups, and cast changes into one global package, with specific rules for what can be billed separately. Getting that line wrong means either underbilling legitimate separate care or overbilling what's already bundled.

Impact: Underbilling when services fall outside global care or overbilling bundled services

Expensive Implants Not Billed Separately Are a Direct Loss

Plates, screws, and prosthetics require their own billing line with proper documentation and manufacturer information. Miss that step and the cost of the hardware itself is money the practice never recovers.

Impact: Significant financial loss when expensive implants are not properly billed

Multiple Surgeries in One Session, Reimbursed for All of Them

When your surgeon performs more than one procedure in the same session, how the claim is built and sequenced decides whether each is reimbursed or whether the additional work quietly collapses into a single payment. Get it wrong and real surgical revenue simply disappears.

Impact: Revenue loss from bundled procedures when modifiers are not correctly applied

Workers' Comp Orthopedic Claims Run on a Completely Different Set of Rules

Work-related orthopedic injuries carry different billing requirements, fee schedules, and authorization processes than standard insurance. Treating them like a regular claim causes payment delays and denials.

Impact: Delayed payments and denials from workers comp-specific requirements

In-Office Imaging Gets Underpaid When Only Half of It Is Claimed

When you own the X-ray or ultrasound equipment and read the images yourself, your practice is entitled to be paid for both the equipment and the physician's interpretation. Claim only one side of that and you collect a fraction of what the imaging is actually worth.

Impact: Reduced reimbursement when component modifiers are not used correctly

Orthopedic Billing Deep Dive: Advanced Strategies

The Economics of the Global Surgical Period

Most orthopedic surgery comes with a 90-day global period: the insurer pays a single surgical fee that is meant to cover the operation plus the routine follow-up that normally goes with it. The problem is that not everything a surgeon does in those 90 days is routine. A complication that sends the patient back to the OR, a brand-new injury to a different joint, or a visit that has nothing to do with the original surgery are all separate, payable work - but only if the claim is built to show that clearly.

Where the money leaks

Practices that don't track the window carefully end up losing both ways: they write off legitimate follow-up revenue out of caution, or they bill for care that was already covered and expose themselves to recoupment when a payer audits. Getting this right on a busy surgical practice adds up to real money across a year.

Every surgical patient's 90-day window tracked so nothing billable slips past unnoticed

Return-to-OR complications and unrelated new injuries billed as the separate work they are

A clean, documented line between bundled follow-up and separately payable care

Protection on both sides - captured revenue without the audit risk of overbilling

Getting Paid Back for Implants and Hardware

Implants and hardware are frequently the single largest cost in an orthopedic case, and the surgeon's professional fee doesn't cover them. Whether the practice or the facility carries that cost, the price of the device has to be documented and claimed on its own so it comes back rather than eroding the margin on an otherwise profitable surgery.

Holding up under audit

Payers scrutinize high-cost device claims closely, and when a practice can't produce the manufacturer, invoice, and case detail behind an implant, the whole claim can be clawed back. Tracking device cost against what each payer actually reimburses also shows you where a particular implant or contract is losing money - information you can use to renegotiate.

Why Second Procedures and Both-Side Cases Get Underpaid

When a surgeon performs more than one procedure in the same session, insurers pay the highest-value procedure in full and reduce what they pay for each additional one - so the order the claim is built in directly changes the total the practice collects. Both-sides-in-one-day cases (a bilateral knee or hip, for example) have their own payment math, and different insurers handle them differently, which means the same surgery can pay noticeably more or less depending on how the claim is submitted to that specific payer. Multi-surgeon cases add another layer.

Why it goes unnoticed

None of this is visible on the surface, which is exactly why so much of it is left uncollected: the claim looks paid, just not paid in full. Building each claim to the paying insurer's actual rules is where that lost revenue is recovered.

Claims sequenced so the highest-value procedure is never the one that gets discounted

Bilateral, same-day cases built to each insurer's specific payment rules for both sides

Multi-surgeon cases documented so each surgeon is paid for their portion

Recovered revenue on complex sessions that otherwise looks 'paid' but isn't paid in full

Fracture Care: What the Initial Treatment Payment Actually Buys

When your practice treats a fracture, the payment for that initial treatment is a package. It covers the reduction or fixation itself and a defined stretch of routine healing checks afterward, and how long that stretch runs depends on how the fracture was treated: a simple splint on a non-displaced break carries a short follow-up window, while a manual reduction or open surgical fixation carries the full post-surgical one. The billing decision at the first encounter therefore sets the revenue for the whole episode.

Two costly mistakes

Two mistakes are common. Practices bill routine cast checks that the package already paid for, inviting denials and takebacks. Or they treat everything in the window as free and never bill the care that genuinely falls outside it, like a new injury to a different bone or delayed healing that changes the treatment plan. Each fracture claim also has to state whether the visit is the first treatment or follow-up care, and whether healing is proceeding normally. A follow-up visit billed as if it were the first encounter is a denial the practice created for itself.

The treatment approach chosen at the first visit determines the follow-up window, so it has to be billed to match what was actually done

Routine cast changes and healing checks inside the package are never billed twice

Delayed healing, nonunion, and new injuries flagged and billed as the separate care they are

Every fracture claim states initial versus follow-up status correctly, closing off a routine denial source

Injections and Office Visits on the Same Day

Joint injections look simple and are miscoded constantly. Payment depends on the size of the joint, and on whether the injection was performed under ultrasound guidance: a guided injection is billed as a single guided service, because adding the imaging as its own line duplicates work the guided service already includes and gets the imaging denied.

Practices that have invested in point-of-care ultrasound often keep billing the unguided service out of habit, giving up the higher guided payment on every needle they place.

The same-day visit

The bigger fight is the same-day office visit. When a patient is evaluated and injected in one appointment, the visit is only payable when it stands on its own as a distinct, separately identifiable service, meaning the note documents real decision-making beyond the choice to inject. Payers now read those notes closely, and a visit note that only records the injection indication is a visit the practice will not be paid for. The fix is documentation review before submission, not appeals after.

Guided injections billed as the guided service, never as an unguided injection plus a separate imaging line

Joint-size classification matched to the anatomy in the note so the claim pays at the right tier

Same-day visits billed only when the documentation supports a distinct, separately identifiable service

Injection documentation checked before submission so the visit survives payer scrutiny

Scope Procedures That Collapse Into One Payment

Arthroscopy has its own quiet revenue problem: procedures performed through the same scope in the same joint frequently merge into a single payment under payer bundling rules. A diagnostic look almost always folds into the surgical work that follows it, and a debridement usually folds into any more comprehensive procedure done in the same session. Billing them as separate lines anyway is an unbundling error that draws audits rather than extra payment.

When extra work pays

The opposite failure costs just as much: when a surgeon genuinely works in two distinct compartments or on separate structures, the additional work is payable, but only when the operative report spells out where each piece happened and the claim is built to show it. There is also a matching problem between the note and the claim. An operation billed as open when the report describes a scope, or the reverse, is denied on review regardless of how well the surgery went.

Every multi-procedure scope claim should be validated against current bundling rules before it goes out, with the operative report as the source of truth.

Multi-procedure arthroscopy claims checked against current payer bundling rules before submission

Diagnostic looks and routine debridement never billed on top of the surgical work that includes them

Genuinely distinct compartments and structures documented so the additional work is actually paid

Surgical approach on the claim always matches the operative report, eliminating a whole class of denials

What Each Payer Expects

Navigate payer-specific requirements for orthopedic procedures, from Medicare inpatient case-rate reimbursement and ambulatory surgery center billing rules to commercial prior authorization timelines and workers' compensation fee schedule complexities.

Medicare

Medicare - Inpatient Joint Replacement

For inpatient joint replacements, Medicare pays a fixed amount that swings substantially based on the patient's documented complications and other conditions - thorough documentation is the difference between full and reduced payment
In Medicare's mandatory TEAM bundled-payment areas, hospitals are accountable for the cost of the surgery and the 30 days after discharge, so post-surgery coordination matters
Complex, sicker patients only pay appropriately when their conditions are fully captured on the record - otherwise the practice absorbs the added cost
Readmissions after joint replacement carry direct financial penalties, making discharge planning and documentation a revenue issue

Medicare

Medicare - Outpatient & Surgery Centers

Medicare keeps expanding which orthopedic surgeries can be done in a surgery center rather than a hospital - where a case is performed can meaningfully change what the practice collects
High-cost implants used in the outpatient or surgery-center setting can qualify for separate payment on top of the procedure, but only when device eligibility is verified and claimed
The same procedure often pays more in one setting than another, so site-of-service is a revenue decision worth making deliberately
When the practice owns the imaging equipment and reads the images, both sides of that work must be claimed correctly - billing it wrong invites recoupment

Commercial

Commercial Insurers

Elective orthopedic surgery almost always needs approval in advance, and the approved plan has to match what's actually performed - a mismatch is a denial the practice eats after the surgery is already done
Most commercial plans require documented conservative treatment first (therapy, injections, time) before they'll approve surgery; missing that paper trail sinks the authorization
Many insurers require specific implant brands for full payment, and using a non-preferred device can cut reimbursement sharply - verify this before the case, not after
Some plans offer higher rates to practices that meet their quality and cost benchmarks, which is real upside worth pursuing

All payers

Workers' Compensation

Comp pays off its own state fee schedules that look nothing like commercial or Medicare rates, so surgical claims have to be built and priced for comp specifically or the surgeon is underpaid
Surgical comp cases need employer and carrier authorization up front, with the work-related injury clearly documented - skip it and the whole claim can be denied after the fact
Independent medical exams and impairment-rating reports are billable physician services in their own right, not free paperwork, and should be collected on
Disputed and delayed comp surgical claims and liens need active follow-up to actually pay out - this is where surgeons most often give up revenue they've already earned
Several states require their own workers' comp claim forms and shorter filing deadlines - miss the state's paperwork rules and a well-paying claim dies on a technicality
Personal injury and auto cases bill against liability policies and attorney liens on their own timeline, sometimes years, and need coordination with counsel so the practice is actually in line to be paid when the case settles
