Temporomandibular Disorders | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0028 covering temporomandibular disorders (TMD), effective March 14, 2026. Here's what billing teams need to do.

Aetna's TMD coverage policy under CPB 0028 has been updated — and if your practice treats jaw pain, bite dysfunction, or related orofacial conditions, this revision affects how you document medical necessity and submit claims. The policy does not publish specific CPT or HCPCS codes in the version currently available, so your billing team will need to cross-reference your charge master against Aetna's full policy document directly. What we do know: this is a modification, not a new policy, which means criteria have shifted and prior claims may not reflect current coverage rules.

Aetna Temporomandibular Disorder Coverage Criteria and Medical Necessity Requirements 2026

Aetna's CPB 0028 Aetna system policy governs whether TMD treatment gets paid — or denied. This coverage policy has historically drawn a hard line between dental benefit coverage and medical benefit coverage for TMD, and that distinction is where most claim denial risk lives.

TMD is one of the messiest billing categories in the dental-medical crossover space. Treatment can span physical therapy, oral appliances, imaging, injections, and surgery. Each of those buckets triggers different coverage rules, different benefit categories, and different prior authorization requirements. A modification to CPB 0028 can shift which treatments Aetna considers medically necessary under the medical benefit versus what it carves out as a dental benefit — or excludes entirely.

Medical necessity under Aetna's TMD policy has generally required documentation of a diagnosed TMD condition, failure of conservative management, and evidence that the requested treatment is appropriate for the specific diagnosis. Aetna evaluates TMD claims against functional impairment criteria — not just pain. That means your documentation needs to show what the patient cannot do, not just what hurts.

Prior authorization is typically required for surgical interventions and for certain imaging (particularly MRI of the temporomandibular joint). If CPB 0028's modification touched prior auth requirements — expanding them, narrowing them, or changing the required documentation — your team needs to know before submitting. Check the full policy at app.payerpolicy.org/p/aetna/0028. before assuming last year's prior auth rules still apply.

Because the specific policy document details are not available in this version summary, confirm the exact updated criteria directly at Aetna's CPB 0028 policy page before the effective date of March 14, 2026.

Aetna TMD Exclusions and Non-Covered Indications

Aetna has historically classified several TMD-adjacent treatments as experimental, investigational, or not medically necessary. These are the areas where your billing team is most likely to run into claim denial.

Occlusal adjustment and equilibration — Aetna has traditionally excluded bite adjustment procedures when performed primarily for TMD treatment. If CPB 0028's modification touched this exclusion, it changes your reimbursement exposure for those claims.

Oral appliances billed to medical — This is a perennial problem. Oral splints and occlusal splints for TMD often fall into a gray zone between dental and medical benefits. Aetna's coverage policy typically requires specific criteria to be met before these devices are covered under the medical benefit. Billing these to medical without meeting those criteria is a fast path to denial and potential overpayment recovery.

Unproven therapies — Treatments like prolotherapy, low-level laser therapy, and certain biofeedback approaches have not consistently met Aetna's medical necessity threshold for TMD. If your practice offers integrative or emerging pain management approaches, verify each one against the updated CPB 0028 before billing.

Surgical interventions without conservative treatment failure — Aetna's policy has historically required documented failure of non-surgical management before approving arthroscopy, arthroplasty, or total joint replacement for TMD. The modification may have changed the specific documentation requirements here.

If you're not sure how your treatment mix maps to the updated exclusions, loop in your compliance officer before the March 14, 2026 effective date.

Coverage Indications at a Glance

The policy document details are not available in this update summary. The table below reflects Aetna's historically documented TMD coverage positions. Treat these as a starting framework — verify each indication against the full updated CPB 0028 policy before billing.

Important: Because the specific CPT, HCPCS, and ICD-10 codes were not published in the policy data available for this update, every "relevant codes" entry above requires direct verification. Do not submit claims based on assumed codes.

Aetna Temporomandibular Disorder Billing Guidelines and Action Items 2026

Here's what your billing team should do right now — before March 14, 2026.

CPT, HCPCS, and ICD-10 Codes for Temporomandibular Disorders Under CPB 0028

The policy data available for this update does not include specific CPT, HCPCS, or ICD-10 codes. Aetna's CPB 0028 policy document — available directly through Aetna's provider portal — contains the authoritative code list.

Do not infer or assume codes based on historical versions of this policy. Code additions, deletions, and description changes occur with policy modifications. Your billing team should pull the current code table directly from the updated policy before submitting any TMD claims under the March 14, 2026 effective date.

When you access the full policy, look for codes across these categories:

• Diagnostic imaging — TMJ MRI, panoramic radiographs, CT imaging of the jaw
• Surgical procedures — arthrocentesis, arthroscopy, arthroplasty, condylectomy, and orthognathic procedures
• Non-surgical treatment — physical therapy procedure codes, oral appliance codes (watch for dental benefit vs. medical benefit designation)
• Injection procedures — corticosteroid injections, nerve blocks, and any botulinum toxin codes if covered under your patient's plan
• Evaluation and management — confirm whether any E/M codes are specifically addressed in the updated policy for TMD encounters

Once you have the code list, flag any codes that are new to the policy, any codes that moved between covered and non-covered status, and any codes with updated documentation requirements.
