# Atlas Commons research objects — Medicare Advantage organization directory entry for UnitedHealthcare (contract H1659)

CMS Medicare Advantage Plan Directory entry for UnitedHealthcare (contract H1659): organization identity (type, plan type, parent, CMS region), enrollment, and directory contact — all verbatim CMS-published values (RECORDED). Epistemic status of each figure is labeled. This is an organizational directory — not plan benefits, premiums, or star ratings; use medicare.gov/plan-compare to compare actual plans. CC0.

## Claims

### UnitedHealthcare (contract H1659) is a CMS-contracted Local CCP offering Local PPO plans

**RECORDED.** The CMS Medicare Advantage Plan Directory records UnitedHealthcare (legal entity: CARE IMPROVEMENT PLUS SOUTH CENTRAL INSURANCE CO., contract number: H1659) as a Local CCP offering Local PPO plans. Contract effective date: 01/01/2011. Tax status: For Profit. CMS region: Boston. Parent organization: UnitedHealth Group, Inc.. These are verbatim CMS directory values; accuracy depends on carrier submissions to CMS.

Source: CMS Medicare Advantage Plan Directory — https://www.cms.gov/medicare/health-drug-plans/medicare-advantage
Falsifier: Verify at the CMS MA Plan Directory (https://www.cms.gov/medicare/health-drug-plans/medicare-advantage) by looking up contract number H1659. Falsified if the CMS directory contradicts these values.

### UnitedHealthcare (contract H1659) has 2,412 reported CMS enrollment

**RECORDED.** The CMS Medicare Advantage Plan Directory reports enrollment of 2,412 for UnitedHealthcare (contract H1659). This is a verbatim CMS-published figure from the plan directory — it is the enrollment as submitted to CMS, not a count of current active members or a ranked figure.

Source: CMS Medicare Advantage Plan Directory — https://www.cms.gov/medicare/health-drug-plans/medicare-advantage
Falsifier: Verify at the CMS MA Plan Directory for contract H1659. Falsified if the CMS directory shows a different enrollment figure.

### CMS MA Plan Directory contact for UnitedHealthcare (contract H1659)

**RECORDED.** The CMS MA Plan Directory lists the following directory contact for UnitedHealthcare (contract H1659): name: UHC Customer Service; phone: 1-866-272-1967; email: UHCMedicareCustomerService@uhc.com; address: 9800 Health Care Lane, Minnetonka, MN, 55343. Last updated per CMS: 12/27/2024. This is the contact as submitted by the organization to CMS — it is not a consumer help line; it is the CMS-directory administrative contact.

Falsifier: Verify at the CMS MA Plan Directory for contract H1659. Falsified if the CMS directory shows different contact information.

### What this Medicare Advantage directory entry is — and is NOT — for UnitedHealthcare (the epistemic boundary)

**INTERPRETATION.** This page is a directory of the organization offering Medicare Advantage / PACE plans under CMS contract H1659. It lists who the organization is, its type, parent, CMS region, and enrollment — verbatim from the CMS MA Plan Directory. It is NOT a directory of individual plan benefits, premiums, deductibles, drug formularies, or star ratings. Enrollment is a CMS-reported count, not a quality signal. To compare actual Medicare Advantage plans available in your area — including premiums, coverage, and star ratings — use the official Medicare Plan Finder at medicare.gov/plan-compare.

Source: Coverage Atlas framing (over the CMS MA Plan Directory facts above) — https://coverage-atlas.ryanjhunter.workers.dev/coverage/medicare-advantage/h1659
Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (the atlas's reading, not a CMS verdict) — the LOWEST-warrant claim here. The org identity, enrollment, and contact above are verbatim CMS records; this boundary note is interpretation.

Every claim above carries a four-status warrant (RECORDED / MODELED / DERIVED / INTERPRETATION) and a named source you can re-fetch — this is a research object, not a flat fact. Structured: `https://coverage-atlas.ryanjhunter.workers.dev/coverage/medicare-advantage/h1659.jsonld`
