Medicare Part D Prescription Coverage 2026 - California

The Medicare Part D creditable coverage information below applies to California group health plans with plan years beginning in 2026, including plans installed or renewed with effective dates from January 1 through December 1, 2026.
Word & Brown has collected Medicare Part D creditable coverage determinations from our fully insured carrier partners. The information below identifies California health plans considered non-creditable for the 2026 plan year. These determinations remain applicable throughout the employer's 2026 plan year, even when that coverage extends into 2027.
Beginning with plan years starting in 2027, new federal testing standards apply when determining whether prescription drug coverage is creditable or non-creditable. Some plans that were considered creditable in 2026 may no longer qualify under the updated 2027 standards.
What Employers Should Know About Their 2026 Plan Year
Employers should use the Medicare Part D creditable coverage status that applies to their current group health plan year when preparing notices for Medicare-eligible employees and dependents.For example, an employer whose group health plan renewed December 1, 2026, would continue using its 2026 creditable coverage determination until its next renewal on December 1, 2027, provided the plan's coverage and creditable status remain unchanged.
Employers must provide an annual Medicare Part D notice before October 15 each year (no later than October 14), informing Medicare-eligible individuals whether their prescription drug coverage is creditable or non-creditable. Notices are also required at other times, including when an individual first becomes covered and when the plan's creditable coverage status changes.
For plans beginning or renewing in 2027, employers should review the updated determinations under the new federal standards. See our 2027 California Medicare Part D Creditable Coverage listing for the applicable plan information.
