TL;DR: Aetna modified CPB 0432 covering computerized motion diagnostic imaging, effective September 26, 2025. Here's what billing teams need to know before submitting claims under CPT 0693T, 96000, 96001, and 96004.
Aetna, a CVS Health company, updated its computerized motion diagnostic imaging coverage policy under CPB 0432 in the Aetna CPB 0432 system. The policy governs four CPT codes—0693T, 96000, 96001, and 96004—used for vertebral motion analysis, DARI scans, and functional motion analysis. If your practice bills these services for patients with vertebral subluxation or somatic dysfunction diagnoses in the M99 range, this update directly affects your reimbursement and claim submission process.

Aetna Computerized Motion Diagnostic Imaging Coverage Criteria and Medical Necessity Requirements 2025
The core question here is whether Aetna considers computerized motion diagnostic imaging medically necessary—and the short answer is: it's complicated, and you need to document carefully.
CPB 0432 covers four distinct procedures under the umbrella of computerized motion diagnostic imaging. CPT 96000 is comprehensive computer-based motion analysis using video and 3D kinematics. CPT 96001 adds dynamic plantar pressure measurements during walking—relevant for practices billing gait analysis. CPT 96004 covers physician or qualified healthcare professional review and interpretation of the comprehensive analysis. CPT 0693T covers full-body, markerless 3D kinematic and kinetic motion analysis (the DARI scan), which is the newest and most scrutinized of the four.
The medical necessity bar for these services is high. Aetna's coverage policy ties coverage to specific diagnostic contexts—primarily vertebral motion analysis and functional motion evaluation. The ICD-10 codes Aetna lists span the entire M99 range: M99.0 through M99.9, covering segmental and somatic dysfunction, subluxation complex of the vertebral column, and subluxation stenosis of the neural canal.
That's a wide diagnostic net on paper. In practice, your documentation has to show the motion analysis directly informs treatment decisions. Aetna won't pay for these studies as standalone curiosities. The clinical record must connect the motion imaging to a specific functional question that can't be answered by standard imaging or physical examination.
Prior authorization requirements for CPT 0693T in particular are worth verifying at the plan level before you schedule the scan. The DARI motion analysis system is relatively new technology, and Aetna has a history of treating newer diagnostic tools as experimental until clinical evidence catches up. Check the specific member's plan documents and call for a prior auth determination before billing CPT 0693T.
Aetna Computerized Motion Diagnostic Imaging Exclusions and Non-Covered Indications
The real issue here is CPT 0693T. Aetna groups it under the same "vertebral motion analysis, DARI scan (functional motion analysis)" category as the other three codes—but 0693T is a Category III CPT code. That classification alone signals that payers, including Aetna, may treat it differently from Category I codes like 96000, 96001, and 96004.
Category III codes represent emerging technology. Many Aetna plans exclude Category III codes by default or require explicit plan-level coverage decisions. If a member's plan does not specifically list 0693T as covered, you face a high claim denial risk regardless of medical necessity documentation.
Routine motion analysis without a clear diagnostic or treatment-planning purpose is also not covered. Aetna's coverage policy does not support these services for wellness, general fitness assessment, or occupational screening purposes. The diagnosis must map to an M99.x code or an equivalent that reflects actual musculoskeletal dysfunction.
Coverage Indications at a Glance
| Indication | Status | Relevant CPT Codes | Key ICD-10 Codes | Notes |
|---|---|---|---|---|
| Vertebral motion analysis with 3D kinematics | Coverage depends on plan | 96000, 96004 | M99.0–M99.9 | Must document medical necessity; not for routine screening |
| Gait analysis with dynamic plantar pressure | Coverage depends on plan | 96001, 96004 | M99.0–M99.9 | Often requires separate prior auth at plan level |
| Full-body markerless 3D motion analysis (DARI scan) | Likely not covered / Experimental | 0693T | M99.0–M99.9 | Category III code; verify plan-level coverage before scheduling |
| Review and interpretation of motion analysis | Coverage follows base service | 96004 | M99.0–M99.9 | Only separately billable when base analysis (96000 or 96001) is covered |
| Functional motion analysis for somatic dysfunction | Coverage depends on plan | 96000, 96001, 96004 | M99.0, M99.1–M99.9 | Clinical record must support diagnostic intent |
| Subluxation complex (vertebral) — all body regions | Coverage depends on plan | 96000, 96001, 96004 | M99.10–M99.19 | Segmental somatic dysfunction must be documented |
| Subluxation stenosis of neural canal | Coverage depends on plan | 96000, 96001 | M99.20–M99.29 | Strong documentation of functional deficit required |
Aetna Computerized Motion Diagnostic Imaging Billing Guidelines and Action Items 2025
Here's what your billing team needs to do before September 26, 2025, and immediately after.
| # | Action Item |
|---|---|
| 1 | Verify plan-level coverage for CPT 0693T before booking any DARI scans. Call Aetna member services or check the provider portal for each patient's specific plan. Category III codes are excluded by many commercial plans. A denial on 0693T is largely preventable with a five-minute eligibility check. |
| 2 | Pull all open authorizations for CPT 96000, 96001, and 96004 and confirm they still apply after the effective date of September 26, 2025. Policy modifications sometimes reset prior authorization requirements. Don't assume an auth granted in August carries through October. |
| 3 | Update your charge capture to require M99.x diagnosis codes for all motion analysis claims. CPT 96000, 96001, 96004, and 0693T must link to a supported ICD-10 code. The full M99 range—M99.0 through M99.9—is listed in CPB 0432, but your documentation must reflect the specific sublevel code (e.g., M99.11 for subluxation complex of the cervical region, not just M99.1). |
| 4 | Audit your CPT 96004 billing patterns now. CPT 96004 is the review and interpretation code—it's only billable when the underlying analysis (96000 or 96001) is also covered and separately documented. If you've been billing 96004 standalone or without the base service, expect denials. Fix your claim pairing logic before September 26. |
| 5 | Document the clinical rationale explicitly in the medical record. Aetna's medical necessity standard requires the motion analysis to directly inform a treatment decision. "Patient has back pain" isn't enough. The note should state what diagnostic question the motion analysis answers and how the result changes the treatment plan. |
| 6 | If your practice uses DARI motion analysis frequently, loop in your compliance officer before the effective date. The intersection of a Category III code, updated policy language, and Aetna's scrutiny of experimental technology creates real financial exposure. Your compliance officer and billing consultant should review your current claim volume and authorization patterns before you bill a single post-September 26 claim for CPT 0693T. |

A note on ICD-10 specificity: The policy lists both parent codes (M99.0, M99.1, M99.2) and their sublevels (M99.10–M99.19, M99.20–M99.29). Always bill the most specific sublevel code available. Billing M99.1 when M99.11 applies is a coding error that invites a claim denial or an audit flag. Map to the specific anatomical region documented in the record.
