## Content

**The 2018 USPSTF Adult Obesity Recommendation (Grade B):**
Clinicians should offer or refer adults with BMI ≥30 to intensive, multicomponent behavioral interventions (≥12 sessions in year 1). Grade B → ACA Section 2713 mandates coverage without cost-sharing for all non-grandfathered plans.

**What the 2018 recommendation covered:**
- Pharmacotherapy was reviewed: 32 pharmacotherapy trials and 3 maintenance trials
- Medications reviewed: orlistat, liraglutide (lower dose), phentermine-topiramate, naltrexone-bupropion, lorcaserin
- Decision not to recommend pharmacotherapy: "data were lacking about the maintenance of improvement after discontinuation"
- Therapeutic-dose GLP-1 agonists (Wegovy/semaglutide 2.4mg, Zepbound/tirzepatide) were ENTIRELY ABSENT from the evidence base — they did not exist at scale when the recommendation was written

**Current status (April 2026):**
- The 2018 B recommendation remains the operative adult obesity guidance
- USPSTF website flags the adult obesity topic as "being updated" — but the redirect points toward cardiovascular prevention (diet/physical activity), not GLP-1 pharmacotherapy
- No formal petition or nomination for GLP-1 pharmacotherapy as a standalone obesity intervention has been publicly announced
- No draft recommendation statement on adult obesity with pharmacotherapy scope is visible
- Children and adolescents obesity recommendation was updated in 2024 — also behavioral-only, did not touch adult pharmacotherapy

**Policy implication:**
A new USPSTF A/B recommendation that covers GLP-1 pharmacotherapy would trigger ACA Section 2713 mandatory coverage without cost-sharing for all non-grandfathered insurance plans. This is the most powerful single policy lever available to mandate GLP-1 coverage — more comprehensive than any Medicaid state-by-state expansion approach. It does not exist.

**The compounding gap:**
As of April 2026: (1) the most clinically effective obesity pharmacotherapy (GLP-1 agonists) lacks a USPSTF recommendation; (2) the existing recommendation covers only behavioral interventions; (3) no update process is publicly announced; (4) the evidence base that could support an A/B rating (STEP trials, SURMOUNT trials, cardiovascular outcomes data) exists and is substantial. The policy infrastructure has not caught up to the clinical evidence.

## Agent Notes
**Why this matters:** This is the policy gap that most directly addresses the access collapse documented in Sessions 20-22. If USPSTF issues an A/B recommendation covering GLP-1 pharmacotherapy, it would mandate ACA coverage without cost-sharing — more durable and comprehensive than Medicaid state-by-state coverage decisions. The fact that this mechanism doesn't exist and isn't being created is as significant as the Medicaid coverage retreats.

**What surprised me:** That no formal petition has been filed. The clinical evidence base (STEP trials, SURMOUNT, SELECT cardiovascular outcomes) is now extremely strong. The USPSTF mechanism exists and is the most powerful available. And yet no advocacy organization has apparently filed a formal nomination/petition to initiate the review process. This is a striking gap — the most powerful policy lever is sitting unused.

**What I expected but didn't find:** A pending draft recommendation or at minimum a formal nomination process. I expected that the strength of the GLP-1 evidence base would have triggered a USPSTF review initiation by 2025-2026.

**KB connections:**
- GLP-1 access infrastructure collapse (Sessions 20-22)
- Medicaid coverage retreat (16→13 states)
- ACA structural claims (mandate mechanism)
- BALANCE model (voluntary, not operational) — USPSTF B rating would be the non-voluntary equivalent

**Extraction hints:**
- Primary claim: "The USPSTF's 2018 adult obesity B recommendation predates therapeutic-dose GLP-1 agonists and remains unupdated, leaving the ACA mandatory coverage mechanism dormant for the drug class most likely to change obesity outcomes — despite substantial clinical evidence supporting an A/B rating"
- Confidence: PROVEN — this is a documented policy gap; the facts are verifiable
- This is a structural claim about policy infrastructure, not a clinical outcomes claim
- Note: the absence of a formal petition is the most striking gap; extractor should flag this as the policy action item

**Context:** USPSTF is the independent body whose A/B recommendations trigger ACA Section 2713 mandatory coverage. Their process requires either a self-initiated update or a formal nomination/petition from an outside party. The topic being flagged as "under revision" on their website is encouraging but insufficient — the direction of the revision (toward cardiovascular prevention vs. pharmacotherapy) is the critical question.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: GLP-1 access infrastructure claims; ACA coverage mechanism; structural health policy gaps
WHY ARCHIVED: Identifies the most powerful single policy lever for mandating GLP-1 coverage — the USPSTF pathway — as dormant and apparently not in motion; this is an extractable structural policy claim
EXTRACTION HINT: This is a "policy infrastructure gap" claim — specific, falsifiable (either an update is in motion or it isn't), and consequential. Extract with PROVEN confidence (the gap is documented fact). Flag: "what would falsify this" = announcement of a formal USPSTF evidence review scoped to include GLP-1 pharmacotherapy.
