Plan facts (CMS CY2026 Landscape file)

How this plan is structured

• 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.
• $4,200 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 = Canadian 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 H3755-001 means

CMS assigns every Medicare Advantage and Part D offering a plan identifier made of three parts. In H3755-001, the leading H marks the contract type (H = Medicare Advantage / Part C contract), the four digits 3755 are the contract number issued to the organization, and the three-digit 001 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).
