Medicare supplement coverage: open enrollment periods.
Summary
Existing federal law provides for the Medicare Program, which is a public health insurance program for persons 65 years of age and older and specified persons with disabilities who are under 65 years of age. Existing federal law specifies parts of Medicare that cover specific services, such as Medicare Part B, which generally covers medically necessary services and supplies and preventive services. Existing law, the Knox-Keene Health Care Service Plan Act of 1975, provides for the licensure and regulation of health care service plans by the Department of Managed Health Care, and makes a willful violation of the act a crime. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing federal law additionally provides for the issuance of Medicare supplement policies or certificates, also known as Medigap coverage, which are advertised, marketed, or designed primarily as a supplement to reimbursements under the Medicare Program for the hospital, medical, or surgical expenses of persons eligible for the Medicare Program, including coverage of Medicare deductible, copayment, or coinsurance amounts, as specified. Existing law, among other provisions, requires supplement benefit plans to be uniform in structure, language, designation, and format with the standard benefit plans, as prescribed. Existing law prohibits an issuer from denying or conditioning the offering or effectiveness of any Medicare supplement contract, policy, or certificate available for sale in this state, or discriminating in the pricing of a contract, policy, or certificate because of the health status, claims experience, receipt of health care, or medical condition of an applicant in the case of an application that is submitted prior to or during the 6-month period beginning with the first day of the first month in which an individual is both 65 years of age or older and is enrolled for benefits under Medicare Part B. Existing law requires an issuer to make available specified Medicare supplement benefit plans to a qualifying applicant under those circumstances who is 64 years of age or younger who does not have end stage renal disease. This bill would delete the exclusion of otherwise qualified applicants who have end stage renal disease, thereby making the specified Medicare supplement benefit plans available to those individuals. The bill, on and after January 1, 2027, would prohibit an issuer of Medicare supplement coverage in this state from denying or conditioning the issuance or effectiveness of any Medicare supplement coverage available for sale in the state, or discriminate in the pricing of that coverage because of the health status, claims experience, receipt of health care, medical condition, or age of an applicant, except as specified, if an application for coverage is submitted during an open enrollment period, as specified in the bill. The bill would entitle an individual enrolled in Medicare Part B to a 90-day annual open enrollment period beginning on January 1 of each year, as specified, during which period the bill would require applications to be accepted for any Medicare supplement coverage available from an issuer, as specified. The bill would require the open enrollment period to be a guaranteed issue period. The bill would authorize premium rates offered to applicants during the open enrollment period to vary based on the applicants' age at the time of issue, as specified, but would prohibit the premiums from varying based on age after the contract is issued. Because a violation of the bill's requirements by a health care service plan would be a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
The bill was amended to delay the effective date of the annual Medicare supplement open enrollment period from January 1, 2026 to January 1, 2027, giving issuers an additional year to prepare. The amendment also added cross-references to the new sections throughout existing law and included a requirement that issuers make all of their policies available to applicants during the open enrollment period. Senate coauthors were updated, with Senator Stern replaced by Senators Wahab and Weber Pierson.
TIMELINE
The effective date for the annual 90-day open enrollment period (new Sections 1358.25 and 10192.25) was delayed one year from January 1, 2026 to January 1, 2027.
REQUIREMENT
Section 10192.11(d) now requires every issuer to make available to every applicant qualified for open enrollment ALL policies and certificates offered by that issuer at the time of application, rather than only a subset.
TECHNICAL
Cross-references were updated throughout Sections 1358.11 and 10192.11 to account for the new annual open enrollment sections (1358.25 and 10192.25), including adding exceptions so that the new guaranteed-issue period does not conflict with existing preexisting condition exclusion rules.
Senate coauthors were changed: Senator Stern was removed and Senators Wahab and Weber Pierson were added.
SCOPE
Section 10192.11(a)(3) was expanded to explicitly state that the section does not prevent exclusion of benefits for preexisting conditions as defined in Sections 10192.8 and 10192.81, clarifying the boundary between the new open enrollment protections and existing preexisting condition rules.
The Senate amendment to SB 242 delays the effective date of the guaranteed-issue open enrollment prohibition from January 1, 2026 to January 1, 2027, and adds a new framework allowing age-based premium differentiation during the annual open enrollment period with specific caps on how much older applicants can be charged relative to the 65-69 age band. The amendment also carves out exceptions to the anti-discrimination and preexisting condition rules specifically during the annual open enrollment period, and expands coauthorship.
TIMELINE
The effective date for prohibiting issuers from denying or conditioning Medicare supplement coverage based on health status, claims experience, receipt of health care, medical condition, or age was moved from January 1, 2026 to January 1, 2027.
REQUIREMENT
New Section 1358.25(b)(4) establishes fixed age bands (under 65, 65-69, 70-79, 80 and over) for premium rates during the annual open enrollment period. The under-65 band cannot exceed 2 times the 65-69 band premium; the 70-79 band cannot exceed 1.25 times; the 80-and-over band cannot exceed 1.5 times. Premiums cannot increase due to age after coverage is in effect, and no lower age band (except under 65) can exceed the immediately higher band.
ELIGIBILITY
An exception was added to the anti-discrimination provision in Section 1358.25(a) stating 'except as specified in paragraph (4) of subdivision (b),' allowing age-based premium variation during open enrollment while still prohibiting discrimination based on health status, claims experience, or medical condition.
SCOPE
The provision allowing issuers to treat under-65 Medicare Part B applicants as a separate risk classification now includes the exception 'Except for during the annual open enrollment period established under Section 1358.25' (and the parallel Section 10192.25 in the Insurance Code), meaning during the annual open enrollment period, under-65 applicants cannot be charged different rates as a separate risk class.
The preexisting condition exclusion provision in Section 1358.11(c) and Section 10192.11(c) now references 'Sections 1358.23 and 1358.25' (and 'Sections 10192.23 and 10192.25'), and the risk classification and preexisting condition exclusions in Section 10192.11(3) are explicitly limited to periods outside the annual open enrollment period.
TECHNICAL
Section 1358.25(a)(1) now references 'subdivisions (a) and (d) of Section 1358.11' instead of just 'subdivision (a),' extending the guaranteed-issue protection to include the disability-based enrollment period.
Coauthors were expanded: Senators Arreguín, Richardson, Wahab, and Weber Pierson were added on the Senate side, and Assembly Member Ransom was added on the Assembly side.
