Joint replacement billing: CPT 27447, 27130, and the TEAM model.
Total knee replacement billing CPT 27447 and total hip replacement billing CPT 27130 look simple — one code, one global fee — until a coder bills a bundled component separately, or a claim lands inside a TEAM hospital's episode without anyone on the billing side understanding what actually changed. This guide covers what's already bundled into the arthroplasty code, the ICD-10 specificity that separates a primary replacement from a revision, the MAC-specific Total Joint Arthroplasty LCD that gates coverage, and exactly what TEAM does and doesn't change about billing.
Key takeaways
- 27447 and 27130 already include synovectomy, meniscectomy, minimal bone grafting, and patella or acetabular resurfacing. Billing any of these separately when performed during the same arthroplasty is a bundling denial waiting to happen, and a recoupment risk if it slips through.
- TEAM's 30-day episode and the CPT code's own 90-day global period are two different clocks. Confusing them is the single most common mechanics error we see billing staff make about this model.
- Four different MACs publish four independently-dated Total Joint Arthroplasty LCDs. CGS, WPS, Wellpoint Federal, and Palmetto GBA each maintain their own — confirmed live against the CMS Coverage Database.
- Revision arthroplasty runs on a completely different ICD-10 family than the osteoarthritis diagnosis that got the patient to surgery — periprosthetic infection and periprosthetic fracture each have their own dedicated codes, and using the original primary diagnosis on a revision claim is a common cause of a medical-necessity denial.
27447 and 27130: what's already inside the code
CPT 27447 reports total knee arthroplasty — replacement of the femoral condyle and tibial plateau, medial and lateral compartments, with or without patella resurfacing. CPT 27130 reports total hip arthroplasty — replacement of the acetabulum and proximal femur, with or without autograft or allograft. Both carry a standard 90-day global surgical period, bringing the modifier 24/58/78/79 logic covered in our orthopedic modifiers guide into play for any reoperation during that window.
Four components are already bundled into both codes when performed as part of the same procedure, and none of them is separately billable on that claim:
| Bundled component | Why it doesn't get its own line |
|---|---|
| Synovectomy | Considered part of the surgical exposure and joint preparation for the arthroplasty itself, not a distinct procedure |
| Meniscectomy (knee) | Removal of remaining meniscal tissue is expected preparatory work for the knee replacement, not a standalone arthroscopic meniscectomy |
| Minimal bone grafting | Routine bone graft to fill small defects encountered during component placement is part of the arthroplasty; a genuinely separate, structural bone-grafting procedure with its own graft harvest is a different clinical scenario and the note needs to say so explicitly before billing it apart |
| Patella resurfacing (knee) / acetabular resurfacing (hip) | Already described in the code's own descriptor as "with or without resurfacing" — there is no separate add-on code for choosing to resurface |
The failure pattern we see most: an operative note documents "extensive synovectomy performed" as a matter of clinical thoroughness, and a coder reads that as a billing cue rather than expected arthroplasty work, appending a separate synovectomy code that denies as bundled almost every time — or worse, gets caught later as a post-payment recoupment. ⚠️ This build could not open CMS's primary NCCI PTP Edits file to confirm the specific modifier indicator for these pairs against 27447/27130 (CMS's site returned an access error to automated fetch attempts); verify the current value in the CMS NCCI PTP Edits Lookup Tool before building a scrubber rule around it.
ICD-10 specificity: primary diagnosis versus revision indications
The diagnosis that clears the Total Joint Arthroplasty LCD for a primary replacement is almost always a laterality- and type-specific code, not an unspecified one — verified live against the FY2026 ICD-10-CM set: M17.11 unilateral primary osteoarthritis, right knee; M17.12 left knee; M16.11 unilateral primary osteoarthritis, right hip; M16.12 left hip. Where etiology differs, that has to show too — M87.851/M87.852 (osteonecrosis, right/left femur) supports a hip arthroplasty for avascular necrosis rather than primary osteoarthritis, and the two read differently to a payer's coverage logic even though both can lead to the same CPT code.
A revision arthroplasty runs on an entirely different diagnosis family, and reusing the original osteoarthritis code on a revision claim is one of the more avoidable medical-necessity denials, because the payer is checking for the complication that necessitated the revision, not the reason the joint was replaced originally. Verified live against the FY2026 set:
| Complication | Code (initial encounter) |
|---|---|
| Periprosthetic joint infection, right hip | T84.51XA |
| Periprosthetic joint infection, right knee | T84.53XA |
| Periprosthetic joint infection, left knee | T84.54XA |
| Periprosthetic osteolysis, unspecified joint | T84.059A |
| Periprosthetic fracture, right hip joint | M97.01XA |
A periprosthetic infection (T84.5x series) and a periprosthetic mechanical fracture (M97 series) are different complications that justify different revision procedures, and the operative note has to support whichever one is on the claim. Full crosswalks against related code families are in our knee and shoulder arthroscopy billing guide and our fracture care billing guide.
The TEAM model: what it actually changes about billing
The Transforming Episode Accountability Model (TEAM) launched January 1, 2026, as a mandatory five-year bundled-payment model, replacing and expanding on the legacy CJR and BPCI-A programs. It puts roughly 700 acute-care hospitals in selected core-based statistical areas at financial risk for a 30-day post-discharge episode covering lower-extremity joint replacement (hip, knee, and ankle), surgical hip/femur fracture treatment, and spinal fusion. CMS sets a bundled target price for that 30-day episode; a hospital that keeps episode spending under the target while meeting its Composite Quality Score gets a reconciliation payment, and one that exceeds it takes a penalty.
That 30-day episode window is not the same thing as the 90-day global surgical period attached to 27447 or 27130, and conflating the two is the single most common mechanics mistake we see in practices that operate inside a TEAM hospital. They run on different clocks, cover different financial exposure, and involve different parties:
| TEAM 30-day episode | 90-day global surgical period | |
|---|---|---|
| Who's at financial risk | The admitting hospital, against a CMS target price | No separate risk pool — it defines what's bundled into the surgeon's own fee |
| What it governs | Total episode spend: the inpatient stay, readmissions, and post-acute care (home health, SNF) inside the window | Which E/M visits and reoperations are bundled into the surgeon's professional fee versus separately billable with 24/58/78/79 |
| Does it change how 27447/27130 is coded? | No — the professional-fee claim is unchanged | This is the mechanism that governs the professional-fee claim, unchanged by TEAM |
| Where it applies | Only inside the selected core-based statistical areas where TEAM is mandatory | Nationally, on every arthroplasty claim regardless of TEAM participation |
What genuinely changes operationally: expect a TEAM hospital's care-coordination team to be far more engaged in discharge destination and post-acute placement than under pure fee-for-service, because those costs now count against its 30-day target price. A surgeon who used to write "discharge to SNF, patient preference" without pushback may now get a call about a lower-cost pathway before the order is finalized — TEAM's incentive structure working as designed, not a billing issue, but a discharge-planning conversation your practice should be ready for.
⚠️ TEAM's launch date, replaced-program history, episode categories, and 30-day/target-price mechanics were verified through web search of current healthcare-industry and law-firm reporting, since no dedicated CMS payment-model connector was available; confirm the 700-hospital figure and the specific participating core-based statistical areas against CMS's own TEAM model page for your hospital, since geographies can be updated.
MAC-specific Total Joint Arthroplasty LCD documentation
"The LCD requires conservative treatment first" is true but incomplete, because Total Joint Arthroplasty coverage is written and maintained separately by each Medicare Administrative Contractor, not as one national policy. Confirmed live against the CMS Coverage Database:
| Article | MAC | Effective date |
|---|---|---|
L40232 | CGS Administrators | 03/15/2026 |
L39911 | WPS Insurance Corporation | 08/27/2026 |
L36039 | Wellpoint Federal | 04/01/2026 |
L33456 | Palmetto GBA | 06/15/2023 |
- 1Confirm the MAC before you pull the checklist. A conservative-care documentation checklist built off one MAC's article and applied to a claim processed by a different MAC is a common, entirely avoidable source of a CO-50 denial.
- 2Document the conservative-treatment trial before scheduling. All four LCDs share the same general structure — PT, analgesics, and often an injection before surgery is medically necessary — but visit counts, durations, and modality requirements differ by MAC.
- 3Commercial payers often run stricter thresholds than any Medicare LCD. A specific PT visit count, a BMI cutoff, or a mandatory second-opinion program are common commercial overlays with no Medicare equivalent — treat a Medicare LCD as context for a commercial claim, never as the governing policy.
⚠️ This build confirmed the article IDs, MAC names, and effective dates above directly against the CMS Coverage Database; the specific documentation thresholds inside each article were not independently re-verified, because CMS's article pages blocked automated retrieval during this build. Pull the specific article text for your MAC before finalizing a checklist against it.
- Use the laterality- and type-specific code that matches the operative indication, not an unspecified default.
- Confirm your practice's specific MAC before pulling an LCD checklist.
- Code a revision with the complication diagnosis that necessitated it — not the original osteoarthritis code.
- Don't bill synovectomy, meniscectomy, bone grafting, or resurfacing separately when performed at the same session as 27447 or 27130.
- Don't reuse the primary osteoarthritis diagnosis on a revision claim.
- Don't tell a surgeon TEAM changed how the professional fee is coded — it didn't.
Build two checklists, not one: a pre-surgical documentation checklist against your MAC's Total Joint Arthroplasty LCD, and a revision-coding checklist mapping each complication type (infection, fracture, osteolysis) to its own ICD-10 family. Practices with only the first are the ones whose revision claims deny for medical necessity, because the reviewer is looking for a complication diagnosis that was never on the claim.

Frequently asked questions
What's bundled into CPT 27447 and 27130 that we shouldn't bill separately?
Synovectomy, meniscectomy, minimal bone grafting, and patella or acetabular resurfacing performed as part of the same arthroplasty are all included in the base code and are not separately billable add-ons. Reporting any of these as a standalone line when they were done during the primary joint replacement is a common cause of an NCCI bundling denial, and in some cases a post-payment recoupment if it's caught on audit rather than at claim submission. If the work went meaningfully beyond what's bundled — a structural bone graft requiring a separate graft harvest, for example — the operative note has to say so explicitly before a separate code is defensible.
Does the TEAM model change how we bill the surgeon's professional fee for a joint replacement?
No. The professional-fee claim for 27447 or 27130 still follows standard fee-for-service rules and the code's own 90-day global surgical package, with the same modifier 24/58/78/79 logic that applied before TEAM existed. What changed is separate from the CPT claim: inside a TEAM hospital's mandatory episode, the hospital carries financial risk on a 30-day post-discharge bundle reconciled against a CMS target price. That's a hospital-level payment mechanic layered on top of an unchanged physician claim, not a change to how the surgery itself is coded or billed.
Which Total Joint Arthroplasty LCD applies to our claim?
It depends entirely on which Medicare Administrative Contractor processes your claim, because Total Joint Arthroplasty coverage is written and maintained separately by each MAC rather than as one national policy. As of this build, CGS Administrators publishes L40232, WPS Insurance Corporation publishes L39911, Wellpoint Federal publishes L36039, and Palmetto GBA publishes L33456 — four independently dated documents, each with its own conservative-care documentation threshold. Confirm your practice's MAC first, then pull that MAC's specific article rather than relying on a generic search result or another practice's checklist.
