What to do
Confirm the plan is fully insured
Ask HR, or look for a state insurance-department marking on the card. In Colorado that marking reads CO-DOI.
Get the Evidence of Coverage
This is the fully insured equivalent of a plan document. It states the covered benefits, the exclusions, and the appeal deadlines.
Check whether a state mandate covers the care
State mandates reach insurers, so they reach this plan. If your state requires coverage, an exclusion in the policy may be unenforceable.
File the internal appeal
At least 180 days from receipt under the federal floor; your policy may allow more. Attach the clinical documentation the denial says is missing, and address the specific criterion the insurer named.
Request external review when the internal appeal fails
An independent organization reviews the file. The decision binds the insurer. This is the step that most often reverses a medical-necessity denial.
File a complaint with the state insurance department in parallel
It costs nothing, it creates a regulatory record, and in some states it is what finally moves the file.
Why fully insured is the strongest position
You have three separate levers instead of one: the plan's own internal process, a binding external review by people who do not work for the insurer, and a regulator with authority over the company. On a self-funded plan the third lever does not exist.
Common questions
- What does CO-DOI on my card mean?
- It marks a plan regulated by the Colorado Division of Insurance, which means Colorado's nondiscrimination regulation and its coverage requirements apply.
- Is the external reviewer really independent?
- Yes. External review is conducted by an independent review organization; the insurer does not choose the outcome and is bound by the decision.

- Colorado bars gender-identity discrimination in the plans its Division of Insurance regulates
Colorado — DOI-regulated plans · effective in force
SUBSTANCE CORROBORATED, NUMBER UNCONFIRMED. 3 CCR 702-4 Series 4-2 (Accident and Health, General) contains gender-identity nondiscrimination text — carriers may not discriminate on the basis of race, color, national origin, disability, age, sex, gender identity, or sexual orientation. But three retrievable CCR snapshots of that series top out at Regulation 4-2-57 and none contains a 4-2-62. The current version (effective 12 Dec 2025) could not be retrieved, so the number is neither confirmed nor refuted. The Division of Insurance's own gender-affirming care page (archived 2026-01-05) cites NO regulation numbers at all, so the citation does not originate from the Division's consumer material either
