TL;DR: The Centers for Medicare & Medicaid Services modified NCD 353, its coverage policy for intensive behavioral therapy for obesity, effective January 9, 2026. Here's what billing teams need to know before submitting claims.
CMS intensive behavioral therapy for obesity coverage policy under NCD 353 Medicare has been updated. This policy governs coverage for face-to-face counseling visits provided by primary care physicians and practitioners to Medicare beneficiaries with a BMI ≥ 30 kg/m². The policy does not list specific CPT or HCPCS codes — you'll need to verify applicable codes with your Medicare Administrative Contractor. The effective date is January 9, 2026.

CMS Intensive Behavioral Therapy for Obesity Coverage Criteria and Medical Necessity Requirements 2026
CMS covers intensive behavioral therapy for obesity under NCD 353. This coverage has been in place since November 29, 2011, but the January 9, 2026 modification makes this an active policy you need to have current in your workflows.
To meet medical necessity under this coverage policy, the beneficiary must have a documented BMI ≥ 30 kg/m². BMI must be calculated by dividing weight in kilograms by the square of height in meters. Document this calculation in the record — don't rely on a verbal report from the patient.
The therapy must follow the 5-A framework: Assess, Advise, Agree, Assist, and Arrange. CMS is explicit about this structure. Your documentation needs to reflect all five components, not just weight and dietary notes. Think of the 5-A framework as your medical necessity checklist for every visit.
Three other requirements define whether a claim will hold up:
| # | Covered Indication |
|---|---|
| 1 | The beneficiary must be competent and alert at the time counseling is provided. |
| 2 | Counseling must be furnished by a qualified primary care physician or other primary care practitioner. |
| 3 | The service must be furnished in a primary care setting. |
All three must be true at the same time. A cardiologist providing this counseling in a specialty clinic doesn't qualify — even if the patient has obesity and the counseling is medically sound. CMS ties reimbursement directly to the primary care setting requirement.
The 5-A Framework in Practice
CMS doesn't just reference the 5-A framework as a courtesy. It's the clinical structure underlying the medical necessity determination. Each component carries documentation weight:
| # | Covered Indication |
|---|---|
| 1 | Assess: Document the behavioral health risk and factors affecting the patient's readiness to change. |
| 2 | Advise: Record that you gave personalized behavior change advice, including specific health harms and benefits tied to this patient's situation. |
| 3 | Agree: Document that you and the patient collaboratively selected treatment goals. "Patient agrees with plan" is not sufficient — show the collaboration. |
| 4 | Assist: Record what behavior change techniques you used. Note any adjunctive medical treatments. |
| 5 | Arrange: Document the follow-up plan, including whether you referred the patient to more intensive or specialized care. |
A claim with thin documentation on any of these elements is a claim denial waiting to happen.
Prior Authorization
NCD 353 does not specify a prior authorization requirement for intensive behavioral therapy for obesity. However, check with your Medicare Administrative Contractor. Some MACs have issued local coverage determinations that add documentation or prior auth requirements at the regional level. Don't assume the national policy is the whole story.
CMS Intensive Behavioral Therapy for Obesity Exclusions and Non-Covered Indications
The biggest coverage cliff in this policy is the six-month weight loss threshold. CMS covers monthly visits in months 7–12 only if the beneficiary achieved a reduction of at least 3 kg over the first six months of intensive therapy.
If the patient does not meet the 3 kg threshold, monthly visits in months 7–12 are not covered. Full stop. This is the point where many billing teams get caught — they keep scheduling and billing monthly visits without verifying that the six-month reassessment happened and that it was documented.
The six-month reassessment is not optional. It's a coverage condition. A reassessment of obesity and a determination of the actual weight loss must be performed at the six-month visit. That determination must be documented in the physician office records. No documentation, no coverage for months 7–12.
Counseling provided by non-primary-care practitioners or in non-primary-care settings is also not covered under this NCD. Specialist settings, urgent care, or hospital outpatient departments fall outside the scope of this policy.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| BMI ≥ 30 kg/m², provided by primary care practitioner in primary care setting | Covered | Not specified in NCD 353 — verify with your MAC | Must follow 5-A framework; beneficiary must be competent and alert |
| Weekly visits, month 1 (weeks 1–4) | Covered | Not specified | One face-to-face visit per week |
| Biweekly visits, months 2–6 | Covered | Not specified | One face-to-face visit every other week |
| Monthly visits, months 7–12 | Covered (conditional) | Not specified | Requires documented ≥ 3 kg weight loss at six-month reassessment |
| Monthly visits, months 7–12, where patient did NOT meet 3 kg threshold | Not Covered | Not specified | Coverage ends; patient may restart with additional face-to-face visits per beneficiary consent |
| Counseling by specialist or in non-primary-care setting | Not Covered | Not applicable | NCD 353 restricts coverage to primary care setting and primary care practitioner |
| Counseling provided when beneficiary is not competent or alert | Not Covered | Not applicable | Competency and alertness at time of service are coverage conditions |
CMS Intensive Behavioral Therapy for Obesity Billing Guidelines and Action Items 2026
The policy modification is effective January 9, 2026. Claims with dates of service on or after that date are subject to this updated policy. Here's what to do now.
| # | Action Item |
|---|---|
| 1 | Verify applicable codes with your MAC before January 9, 2026. NCD 353 does not list specific CPT or HCPCS codes. Obesity behavioral therapy billing requires knowing which codes your MAC accepts for this service. Contact your MAC directly or check their website for any active local coverage determination linked to NCD 353. Do not guess on code selection. |
| 2 | Build the six-month reassessment into your scheduling workflow before the effective date. The 3 kg weight loss determination at month six is a coverage condition for months 7–12, not an administrative courtesy. Set a flag in your EHR or practice management system so the reassessment is automatically scheduled and documented before month-seven billing is triggered. |
| 3 | Audit your provider and setting eligibility. Pull the list of providers currently billing for this service. Confirm each one is a primary care physician or primary care practitioner — not a specialist or ancillary provider. Confirm the setting on each claim is a primary care setting. If you find any mismatches, flag those claims for review with your billing consultant before submitting. |
| 4 | Update your documentation templates to reflect all five components of the 5-A framework. A generic SOAP note doesn't satisfy NCD 353 documentation requirements. Your note needs to show that you assessed, advised, agreed, assisted, and arranged. If your current templates don't have prompts for each of these, update them now — not after a claim denial triggers an audit. |
| 5 | Document the 3 kg threshold determination explicitly at the six-month visit. Don't leave this buried in a weight measurement. The policy says the determination "must be documented in the physician office records." Write it out: the starting weight, the current weight, the calculated difference, and whether the patient qualifies for continued monthly visits. This documentation is your defense if the claim is questioned. |
| 6 | Confirm your visit frequency matches the NCD 353 schedule on every claim. The structure is: weekly for month 1, biweekly for months 2–6, monthly for months 7–12 (if threshold met). Any deviation from this schedule — including billing a visit in the wrong frequency tier — creates a claim denial risk. Build a visit counter into your billing workflow. |
| 7 | If you're not sure how this applies to your patient mix or provider types, talk to your compliance officer before January 9, 2026. The intersection of setting requirements, practitioner type restrictions, and the six-month threshold creates real exposure for practices that see a high volume of Medicare obesity counseling. A compliance review now is cheaper than a post-payment audit later. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Intensive Behavioral Therapy for Obesity Under NCD 353
Covered CPT and HCPCS Codes
NCD 353 does not specify CPT or HCPCS codes in the policy document. This is not unusual for older NCDs — code mapping often lives at the MAC level through a local coverage determination or billing article, not in the NCD itself.
Action required: Contact your Medicare Administrative Contractor to confirm which CPT or HCPCS codes they accept for intensive behavioral therapy for obesity under NCD 353. Do not submit claims without verifying code selection with your MAC. Using the wrong code — even for a covered service — triggers a claim denial that requires an appeal.
Key ICD-10-CM Diagnosis Codes
NCD 353 does not list specific ICD-10-CM codes. The policy defines eligibility by BMI ≥ 30 kg/m², which maps to the ICD-10-CM obesity category. Confirm diagnosis code requirements with your MAC, and use BMI codes as secondary diagnoses where appropriate. Again — verify rather than assume.
