Hip Arthroplasty — CPB 0287 | AETNA Coverage Update

Aetna modified CPB 0287 for hip arthroplasty, effective February 27, 2026. Here's what changes for billing teams.

Aetna, a CVS Health company, updated its hip arthroplasty coverage policy under CPB 0287, affecting CPT codes 27130, 27125, 27132, 27134–27138, and related revision codes. The update tightens medical necessity documentation requirements—especially around conservative therapy and in-person physical therapy—and adds explicit non-coverage designations for robotic surgery (HCPCS S2900), computer-assisted navigation (CPT 0054T, 0055T, 20985), and virtual reality procedural dissociation (CPT 0771T–0774T). If your practice bills total hip arthroplasty or revision procedures for Aetna members, the documentation bar just got higher.

Aetna Hip Arthroplasty Coverage Criteria and Medical Necessity Requirements 2026

The core of this Aetna hip arthroplasty coverage policy is a multi-part medical necessity test. All four criteria must be met for total hip arthroplasty (THA) approval—except when the indication is fracture, malignancy, or implant failure.

Advanced joint disease pathway: The member must show pain and functional disability affecting activities of daily living (ADLs) from osteoarthritis, rheumatoid arthritis, avascular necrosis, or post-traumatic arthritis. Physical exam must document limited range of motion, antalgic gait, and pain with passive ROM. Imaging must show either avascular necrosis at stage II or III, or moderate-to-severe osteoarthritis at Tönnis grade 2 or 3.

The conservative therapy requirement is where most claims run into trouble. Aetna requires at least 12 weeks of documented non-surgical treatment—24 weeks for members with relative contraindications (BMI over 40 or age under 50). At least half of that therapy must be formal, in-person physical therapy with a licensed physical therapist. Home exercise programs and virtual PT do not count toward that threshold.

Aetna will accept PT confirmation from actual PT notes or from the member's claims history. If conservative therapy is documented only in a surgeon's office note without corroborating PT records or claims, expect a denial. Build your pre-authorization submission around actual PT notes.

The six required components of conservative therapy are: anti-inflammatory medications or analgesics, flexibility and muscle strengthening exercises, activity modification, supervised in-person PT with documented ADL decline despite completing a plan of care, assistive device use (required for high-risk members, optional for others), and therapeutic hip injections (required for high-risk members, optional for others).

Fracture and other direct pathways: Aetna covers THA for fracture of the femoral neck by imaging, malunion of acetabular or proximal femur fractures with ADL-limiting pain, nonunion by imaging or failed prior hip fracture surgery, and malignancy involving the bones or soft tissues of the pelvis or proximal femur. These pathways bypass the conservative therapy requirement. Document the imaging clearly—this is a cleaner prior authorization path when the indication qualifies.

Precertification: Aetna's policy flags that precertification may be required for select procedures. Check the CPT code search tool on Aetna's provider portal before scheduling CPT 27130 or any revision code (27134–27138). Prior authorization requirements vary by plan, and a missing auth is a clean-claim killer regardless of medical necessity documentation.

Aetna Hip Arthroplasty Exclusions and Non-Covered Indications

This update is direct about what Aetna won't pay for. The additions to the non-covered list are significant because they reflect technologies that many orthopedic practices now market to patients as premium options.

Robotic surgery (HCPCS S2900) is not covered. Aetna does not consider robotic-assisted hip arthroplasty to have sufficient evidence of superior outcomes to justify separate reimbursement. If your surgeons use robotic systems, that cost stays within the global surgical payment for CPT 27130—you cannot bill S2900 separately.

Computer-assisted surgical navigation under CPT 0054T (image-guided), CPT 0055T (image-guided, additional), and CPT 20985 (image-less navigation) is also not covered. Same logic applies.

Virtual reality procedural dissociation services (CPT 0771T, 0772T, 0773T, 0774T) are non-covered. These codes cover VR-assisted analgesia or dissociation during procedures—Aetna doesn't recognize them for hip arthroplasty indications.

Other non-covered services include obturator nerve blocks (CPT 64450), iliopsoas transfer (CPT 27110), and C-reactive protein as a marker for peri-prosthetic infection (CPT 86140, 86141). The CRP exclusion is worth noting if your orthopedic practice routinely orders inflammatory markers post-op—Aetna won't pay for those under this policy.

Custom joint implants billed under HCPCS L8699 are also not covered when selection criteria are not met.

Copy Action Items

If your practice has a high volume of Aetna hip arthroplasty cases with high-BMI or young patients, talk to your compliance officer before February 27, 2026. The 24-week documentation requirement for that population is a meaningful operational change.
