Musculoskeletal Assessment Systems — CPB 0212 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0212 covering musculoskeletal assessment systems, effective September 26, 2025. CPT codes 0778T, 95851, and 97750 are explicitly not covered for the indications listed in this policy. Here's what billing teams need to know.

Aetna's musculoskeletal assessment systems coverage policy under CPB 0212 Aetna system draws a hard line: surface mechanomyography (sMMG), range of motion measurements, and physical performance testing are non-covered services for the listed indications. If your practice bills any of these codes for Aetna members with musculoskeletal diagnoses or injury-related screening encounters, expect denials. The effective date of September 26, 2025 is already past — which means if you haven't audited your charge capture, you're already behind.

Aetna Musculoskeletal Assessment Systems Coverage Criteria and Medical Necessity Requirements 2025

The Aetna musculoskeletal assessment systems coverage policy under CPB 0212 is structured around non-coverage. There are no covered indications in this update. Aetna does not consider CPT 0778T, 95851, or 97750 to meet medical necessity for the diagnoses and screening encounters listed in the policy.

This matters if your practice treats patients with ICD-10 codes in the M00.00–M99.9 range — that's the entire musculoskeletal and connective tissue chapter. It also covers injury codes S00.00x through T14.91, and a wide set of Z13.820–Z13.828 and Z13.850–Z13.858 screening encounter codes tied to neuromuscular control screenings.

Medical necessity is the sticking point here. Aetna's position is that these assessment tools — whether you're measuring range of motion with 95851 or running a physical performance test under 97750 — don't meet the clinical evidence bar for the indications covered under this bulletin. That's a broad exclusion affecting a large patient population.

Prior authorization won't save you here. If Aetna deems these services non-covered, prior auth is irrelevant — a PA approval doesn't override a coverage policy exclusion. Don't bill these expecting a PA to provide cover.

Aetna Musculoskeletal Assessment Systems Exclusions and Non-Covered Indications

All three CPT codes in this policy sit in the "not covered for indications listed in the CPB" bucket. That phrasing is important. Aetna isn't saying these codes are never payable under any circumstance across all payers — they're saying that for the specific indications addressed in CPB 0212, they don't cover them.

CPT 0778T is the newest code in this group. It covers surface mechanomyography (sMMG) with concurrent inertial measurement unit (IMU) sensors. sMMG is a non-invasive muscle function assessment technology. Aetna considers this experimental or investigational for the indications in this policy. If you've added 0778T to your charge capture recently — it's a newer Category III code — pull it for Aetna patients in these diagnostic categories.

CPT 95851 covers range of motion measurements and report for each extremity (excluding hand) or each spinal section. This is a long-standing code, and many billing teams treat it as routine. For Aetna members with M-series or S/T-series diagnoses, it's non-covered under CPB 0212. That may surprise your physical therapy or rehab billing staff.

CPT 97750 covers physical performance testing or measurement — functional capacity evaluations, musculoskeletal performance tests — with a written report. Again, non-covered for the listed indications. This is a code that generates real revenue in sports medicine and occupational medicine. Losing it on Aetna claims is a meaningful reimbursement hit.

The real issue here is the breadth of the ICD-10 scope. Nearly every musculoskeletal patient and many injury patients fall inside M00.00–M99.9 or S00.00x–T14.91. Pair that with the Z13.820–Z13.858 screening codes, and you're looking at a very wide denial exposure.

Key ICD-10-CM Diagnosis Codes Under CPB 0212

One note on the Z13 codes: the Z13.820–Z13.828 and Z13.850–Z13.858 ranges cover neuromuscular control screenings tied to injury prevention and detection. These are the codes that might come up in sports medicine or occupational health contexts — pre-participation screenings, return-to-play assessments, and similar encounters. Aetna's non-coverage extends to all of them under this policy.

The M00.00–M99.9 range is essentially the entire musculoskeletal chapter of ICD-10. If your practice bills any musculoskeletal diagnosis and uses these assessment codes, this coverage policy change applies to you. There are no carve-outs listed.
