Insurance Appeals and Disputes

Insurance appeals and disputes cover what happens when a health plan refuses to pay for care, denies a treatment as unnecessary, or says a service isn’t covered. Every plan, whether through an employer, the individual market, or a government program, has to give you a way to challenge that decision. Knowing how these appeals work can be the difference between paying out of pocket and getting the care you were promised.

Internal and external review. Most disputes start with an internal appeal, where the insurer itself reconsiders the denial, often requiring your doctor to submit additional records or a letter of medical necessity. If that fails, many plans allow an external review by an independent party not affiliated with the insurer, whose decision can overturn the original denial.

Government programs have their own rules. Medicare, Medicaid, and marketplace plans each follow separate appeal procedures with their own deadlines and levels of review. For anyone enrolled in Medicare, Appealing a Medicare Coverage Decision: A Step-by-Step Guide walks through how that specific process works, from the first request for reconsideration through the later stages of review.

Timing and documentation matter. Appeals almost always run on strict clocks, and missing a deadline can end your case before it’s heard. Keeping copies of denial letters, medical records, and every communication with the insurer gives you the strongest position if a dispute drags on or needs to go before an outside reviewer.
