Eating Disorders — CPB 0511 | AETNA Coverage Update

Aetna modified CPB 0511 for eating disorders, effective December 20, 2025. Here's what billing teams need to know about covered services, hard exclusions, and the long list of procedures Aetna won't pay for.

Aetna, a CVS Health company, updated Clinical Policy Bulletin 0511 covering the assessment and treatment of anorexia, bulimia, and binge-eating disorder. The revised Aetna eating disorders coverage policy draws a sharp line between covered services — including bone density studies (CPT 77080, 77081), psychotherapy (CPT 90832–90838), and metabolic panels (CPT 80047–80053) — and a growing list of biomarker tests, brain imaging, and interventional procedures it now explicitly labels experimental. If your practice bills for psychiatric evaluation, nutritional counseling, or any of the neuromodulation codes in the 61863–61886 range, this policy change belongs on your radar before year-end.

Aetna Eating Disorders Coverage Criteria and Medical Necessity Requirements 2025

The CPB 0511 Aetna system defines medical necessity for eating disorder management along two parallel tracks: assessment and treatment. Both tracks apply specifically to members diagnosed with anorexia or bulimia. Binge-eating disorder gets limited treatment coverage — primarily Vyvanse (lisdexamfetamine dimesylate) — but the assessment criteria don't extend as broadly.

For assessment, Aetna covers the standard workup you'd expect. Blood count and serum chemistry — CPT 85025, 85026, 85027 for CBC and CPT 80047, 80048, 80050, and 80053 for metabolic/health panels — meet medical necessity criteria. So does urinalysis (CPT 81000–81005), liver function testing (CPT 80076), and ECG (CPT 93000). Bone density measurement for anorexic members is covered via CPT 76977, 77078, 77080, and 77081. Psychiatric and psychological evaluation (CPT 90791, 90792) and psychological testing (CPT 96130, 96131, 96136–96139, 96146) are also covered.

On the treatment side, psychotherapy is covered across a wide range of modalities. CPT codes 90832 through 90838 and 90845 through 90853 are all listed as covered when selection criteria are met. That includes cognitive behavioral therapy, family psychotherapy, interpersonal psychotherapy, and psychodynamic psychotherapy. Health behavior assessment and intervention codes — CPT 96156 through 96171 — are also covered. Pharmacologic management (CPT 90863) is covered with formulary caveats.

Nutritional counseling is covered. Enteral nutrition is covered for anorexia, but only as a last resort. Don't bill enteral nutrition as a first-line treatment and expect clean reimbursement.

One coverage policy wrinkle worth flagging: Vyvanse for binge-eating disorder may be excluded under plans that specifically exclude weight-management medications. Check the member's benefit plan before billing. Coverage of particular drugs within each class may be subject to formulary restrictions where applicable — confirm formulary tier with the member's plan before billing.

Aetna Eating Disorders Exclusions and Non-Covered Indications

This is where the policy gets expensive if your team isn't paying attention. Aetna's list of experimental, investigational, or unproven services under CPB 0511 is long and specific. The claim denial risk here is real.

Screening is explicitly excluded. Aetna considers routine screening for eating disorders in asymptomatic adolescents and adults experimental. There's no covered code pathway for population-level eating disorder screening under this policy.

On the assessment side, the following are non-covered:

On the treatment side, neuromodulation procedures are explicitly not covered for eating disorder indications. That means deep brain stimulation — CPT 61863, 61864, 61867, 61868, 61880, 61885, 61886 — and all associated neurostimulator analysis codes (CPT 95836, 95970, 95971, 95976, 95983, 95984) are non-covered. CPT 96020 for neurofunctional testing during brain mapping is also excluded.

The real issue here is scope creep. Eating disorders billing has expanded in recent years as treatment research has grown. Providers are ordering more biomarker panels, more functional imaging, and more advanced neurological assessments. Aetna is drawing a hard line: evidence isn't there yet, and they won't pay.

If your clinicians are ordering any of these tests and billing under eating disorder diagnoses, you'll get denials. Worse, if those services are being billed without documentation of the specific indication, you may have an overcoding problem worth flagging to your compliance officer now — before the December 20, 2025 effective date.
