Bill Summary · HB 947

Legislative bill overview

HB 947 would revise Montana's insurance laws to modify coverage requirements for continuous glucose monitors (CGMs) and related supplies. The bill addresses how health insurance plans must cover these medical devices used by people with diabetes to track blood sugar levels in real-time.

Why is this important

Continuous glucose monitors are critical diabetes management tools that can improve health outcomes and reduce complications, but their cost—often $1,000+ annually—makes them inaccessible without insurance coverage. Changes to insurance coverage requirements directly affect which Montanans can afford this technology and what out-of-pocket expenses they face.

Potential points of contention

  • Coverage scope: Disagreement likely exists over whether insurers should cover all CGM models/supplies or only specific ones, and how often replacements should be covered
  • Cost implications: Insurance companies may resist broad mandates citing premium increases, while patient advocates argue the long-term healthcare savings justify coverage
  • Medical necessity standards: Debate over whether coverage should apply to all diabetics or only those meeting specific clinical criteria (type 1 vs. type 2 diabetes, age restrictions, etc.)
