Generally revise laws relating to insurance coverage relating to cancer
SB 422 requires Montana health insurers to cover FDA-approved drugs for advanced or metastatic cancer without forcing patients to first fail other treatments. It prohibits insurers from demanding that patients prove they've tried and failed alternative drugs before approving coverage for new treatments that align with national cancer guidelines. This directly affects patients diagnosed with advanced or metastatic cancer in Montana, ensuring faster access to potentially life-saving medications without unnecessary bureaucratic hurdles. The law applies only to drugs approved by the FDA and consistent with evidence-based cancer treatment protocols.

MODERATE
The bill was amended to clarify that insurers cannot deny coverage for prescription drugs used to treat advanced or metastatic cancer if they follow FDA approval and national guidelines. The definition of 'terminal cancer' was added, while the definition of 'associated condition' was removed. Additionally, new provisions were added to ensure state legislators and judges can remain on group health plans until they become eligible for Medicare, even if they are no longer actively employed.
Scope change
The bill's scope was narrowed slightly by removing the requirement to cover 'associated conditions' alongside cancer, but it was expanded regarding specific protections for state officials' health benefits.
REQUIREMENT
Removed the requirement for insurers to cover 'associated conditions' (symptoms or side effects) alongside advanced or metastatic cancer, focusing coverage strictly on the cancer itself.
DEFINITION
Added a new definition for 'terminal cancer' as cancer that cannot be cured and is expected to lead to death.
Removed the previous definition for 'associated condition' which covered symptoms or side effects that could jeopardize a patient's health.
ELIGIBILITY
Added specific rules allowing state legislators and judges to remain members of group health plans until they qualify for Medicare, regardless of their employment status.
