Plan facts (CMS CY2026 Landscape file)

How this plan is structured

• $0 consolidated premium. A $0 or near-$0 consolidated premium does not remove the Part B premium — the standard 2026 Part B premium is $202.90 per month and still applies. See the 2026 Medicare Part B premium.
• HMO plan type. In an HMO-style Medicare Advantage plan, in-network care and primary-care referral rules generally apply. See how Medicare Advantage HMO and PPO plans differ.
• $4,900 in-network out-of-pocket maximum. The MOOP is the annual cap on what a member pays in-network for covered Part A and Part B services. See how the Medicare Advantage MOOP works.
• Service area = Los Alamos County. Medicare Advantage plans are sold by service area; moving out of the plan's service area triggers a Special Enrollment Period to switch plans. See how moving changes your Medicare options.

What H1189-007 means

CMS assigns every Medicare Advantage and Part D offering a plan identifier made of three parts. In H1189-007, the leading H marks the contract type (H = Medicare Advantage / Part C contract), the four digits 1189 are the contract number issued to the organization, and the three-digit 007 is the plan benefit package under that contract. The segment ID 0 identifies the service-area segment within the plan (0 = the default single segment).
