Standard premium $202.90/mo; annual deductible $283.00. Full IRMAA tier table in MEDICARE_PARTB_2026 below, transcribed verbatim from the notice's raw text (fetched from the Federal Register API 2026-08-28) — tier comparisons preserve the notice's exact inclusive/exclusive bounds. Promoted 2026-08-28 (delegated): the notice was re-fetched independently and every threshold, adjustment and total re-confirmed against its text; boundary semantics pinned by tests. Immunosuppressive-drug-only premiums not entered (not a planning input). MAGI thresholds are indexed and must be re-entered each fall.
