TL;DR: Aetna, a CVS Health company, modified CPB 0853 governing wrist arthroplasty coverage, effective February 27, 2026. Here's what changes for billing teams.
This update to the Aetna wrist arthroplasty coverage policy tightens the line between covered and non-covered indications. CPT 25446 (total wrist arthroplasty) stays covered — but only for rheumatoid arthritis with a specific treatment failure history. Everything else, including osteoarthritis, post-traumatic arthritis, and a long list of specific devices and procedures, falls into experimental or non-covered territory. If your practice bills CPT 25446, CPT 1003T, or CPT 64772 for Aetna members, this policy directly affects your reimbursement and claim denial risk.

Aetna Wrist Arthroplasty Coverage Criteria and Medical Necessity Requirements 2026
The Aetna wrist arthroplasty coverage policy under CPB 0853 Aetna covers exactly one indication for total wrist arthroplasty: rheumatoid arthritis affecting the wrist.
That's it. One diagnosis, with three supporting requirements.
To meet medical necessity, the patient must have all of the following:
| # | Covered Indication |
|---|---|
| 1 | Radiographic evidence of wrist joint destruction |
| 2 | Diagnosed rheumatoid arthritis (ICD-10 range M05.00–M14.89) |
| 3 | Documented treatment failure — at least three months of NSAIDs, disease-modifying anti-rheumatic drugs (DMARDs), and/or glucocorticoids, as clinically appropriate |
All three criteria must appear in the medical record. Radiographic evidence alone isn't enough. A rheumatoid arthritis diagnosis alone isn't enough. You need the full picture documented before the claim goes out.
CPT 25446 — arthroplasty with prosthetic replacement of the distal radius and partial or entire carpus (total wrist) — is the primary procedure code for this coverage. CPT 1003T for arthroplasty of the first carpometacarpal joint with distal trapezial and proximal first metacarpal prosthesis also falls under this policy when selection criteria are met.
Prior authorization is almost certainly required for CPT 25446 on Aetna commercial plans. Confirm prior auth requirements with the specific plan before scheduling. Submitting without prior auth on a high-cost surgical procedure is a fast path to a claim denial you can't appeal on procedural grounds.
The medical necessity bar here is narrow by design. Aetna is drawing a hard line: rheumatoid arthritis with documented conservative treatment failure gets coverage. Everything else does not. This is not a policy that gives you wiggle room on diagnosis coding.
Aetna Wrist Arthroplasty Exclusions and Non-Covered Indications
This is where CPB 0853 gets detailed — and where most claim denial risk lives.
Aetna considers total wrist arthroplasty experimental, investigational, or unproven for the following diagnoses:
| # | Excluded Procedure |
|---|---|
| 1 | Comminuted distal radius fracture (S52.591A–S52.599S) |
| 2 | Kienbock's disease |
| 3 | Osteoarthritis — primary, secondary, and post-traumatic (M19.131–M19.39) |
| 4 | Post-traumatic arthritis |
| 5 | Scaphoid non-union (S62.001K–S62.036K, 7th character "K" required) |
| 6 | Scapholunate dissociation |
If your surgeon performs CPT 25446 for any of these diagnoses, Aetna will not pay. Document everything you want about the clinical rationale — it won't change the coverage status. These are hard exclusions based on insufficient peer-reviewed evidence, not medical necessity disputes you can argue on appeal.
The policy also names specific devices and procedures as experimental or unproven, regardless of diagnosis:
| # | Excluded Procedure |
|---|---|
| 1 | Integra Freedom Implant — experimental for all indications |
| 2 | Pyrocarbon interposition arthroplasty for pisotriquetral arthritis (M13.811–M13.89) and scaphotrapeziotrapezoid osteoarthritis (M19.41–M19.49) |
| 3 | Selective or complete denervation of the wrist/forearm for any pain diagnosis (M25.531–M25.539, R52) — billed under CPT 64772, which is explicitly not covered under this policy |
| 4 | Semi-constrained distal radioulnar joint prosthesis |
| 5 | The Prosthelast (isoelastic wrist implant) |
| 6 | The Universal 2 total wrist system |
| 7 | Wrist hemiarthroplasty — for rheumatoid arthritis and all other indications including capitolunate arthritis, giant cell tumors of the distal radius (C40.0–C40.2), scaphoid nonunion advanced collapse, and scapholunate advanced collapse (M12.531–M12.539) |
| 8 | Wrist joint prostheses (Motec, ReMotion) for non-rheumatoid wrist arthritis |
The device list matters because surgeons sometimes select implants based on clinical preference or availability. If the implant your surgeon uses is on this list, the claim is denied — full stop — even if the diagnosis would otherwise qualify. Verify implant selection before surgery, not after.
CPT 64772 deserves special attention. Selective or complete wrist denervation is not covered under any diagnosis for any etiology. If your practice performs this procedure, do not bill it to Aetna expecting reimbursement. This is a line-item non-covered service under CPB 0853.

Aetna Wrist Arthroplasty Billing Guidelines and Action Items 2026
Here's what your billing team should do before and after the February 27, 2026 effective date.
| # | Action Item |
|---|---|
| 1 | Audit all queued CPT 25446 and CPT 1003T claims for Aetna before submission. Confirm the diagnosis code is within M05.00–M14.89 (rheumatoid arthritis). If the ICD-10 maps to osteoarthritis, post-traumatic arthritis, or any diagnosis on the exclusion list, do not submit — it will deny. |
| 2 | Verify prior authorization on every CPT 25446 case before scheduling. Call the Aetna plan directly or check the provider portal. Missing prior auth on a surgical procedure this high-value is a denial you won't recover from on appeal. |
| 3 | Confirm documentation of all three medical necessity criteria in the chart. Your coder needs to see: (a) a rheumatoid arthritis diagnosis, (b) imaging reports showing wrist joint destruction, and (c) documented failure of at least three months of NSAIDs, DMARDs, and/or glucocorticoids. Missing any one of these creates a medical necessity denial. |
| 4 | Flag CPT 64772 (wrist denervation) as non-covered under Aetna plans. Update your charge capture system to reflect that this code is excluded under CPB 0853 for all diagnoses. If your surgeons perform wrist denervation, discuss advance beneficiary notice or patient self-pay options before the procedure. |
| 5 | Cross-check implant selection against the excluded device list. Before an Aetna member goes to the OR, confirm the planned implant is not the Integra Freedom, Universal 2, Prosthelast, Motec, or ReMotion system. If it is, the claim is non-covered regardless of diagnosis. Loop in your clinical and supply chain teams now. |
| 6 | Update your denial management workflows for scaphoid nonunion coding. ICD-10 codes S62.001K–S62.036K require the 7th character "K" to indicate nonunion. If your coders are using a different 7th character, the ICD-10 match to the exclusion list may not fire — but the clinical documentation still makes it a non-covered case. Train coders on this specificity. |
| 7 | If your practice treats a high volume of wrist arthritis patients across multiple etiologies, talk to your compliance officer before the effective date. The line between rheumatoid arthritis (covered) and other inflammatory or degenerative arthritis (not covered) can blur in complex cases. Get guidance before a claim denial becomes an audit flag. |
