Dexcom G7 denied by insurance
A continuous glucose monitor, pump, or diabetes supply was denied, or coverage stopped for something you were already using.A denial is the plan's first answer, not the last one, and the rules that follow it are federal.
Holding the denial letter for Dexcom G7? Paste what it says. We pull out the stated reason, the deadline, and the plan language it relies on, then write the appeal with those details in it.
Why Dexcom G7 gets denied
- Criteria usually turn on insulin regimen and testing frequency, and denials commonly follow chart notes that omit both.
- Coverage sits under pharmacy on some plans and durable medical equipment on others, and the same claim can be denied under one and paid under the other.
- Type 2 requests are refused more often than type 1, and documented hypoglycaemia is what usually carries them.
Across diabetes device and supply denials generally, the reasons plans give most often are:
- Criteria not documented, typically insulin regimen details, testing frequency, or documented hypoglycaemia.
- The claim went to the wrong benefit, since some plans cover CGM under pharmacy and others under durable medical equipment, and the same claim can be denied under one and paid under the other.
- A supplier that is not in network or not enrolled for that benefit.
- Diagnosis-type criteria applied narrowly, which is where type 2 requests most often fail.
- Recertification lapsed on a device that had been covered for years.
The angle that tends to matter here
Check which benefit the claim was billed under before writing anything. A large share of these denials are routing errors rather than judgements about need, and refiling under the correct benefit resolves them faster than an appeal.
What to gather before you write
- Chart notes with the insulin regimen and testing frequency.
- Documented hypoglycaemic episodes, especially any that required assistance.
- Recent A1c results.
- The prescriber's statement of why this specific device is required.
Watch out for this one
If a device was previously approved and is now denied, say so in the appeal and give the dates. A plan reversing itself on unchanged facts is a strong point in your favour.
The rights you have, whatever the plan said
- An internal appeal. Federal rules give most plan members at least 180 days from the denial notice to file one. Your own notice states the deadline that governs your plan, so read it and use that date.
- The reason in writing. The plan has to tell you the specific reason for the denial and the plan provision or clinical criteria it relied on. If the letter is vague, ask for the criteria by name.
- Your file. You can request the documents and records the plan used to decide, and it does not cost you anything.
- An outside reviewer. If the internal appeal fails, you have 4months to ask for an external review by an independent organisation. It looks at the claim fresh rather than checking the insurer's work, decides within about 45 days, and its decision binds the plan. This covers denials that turn on medical judgement, which includes medical necessity, level of care, and experimental or investigational calls.
- A faster track when waiting would hurt you. Urgent appeals run on a 72-hour clock, and you can ask for an expedited external review at the same time as the internal one. If a doctor who knows your condition says the situation is urgent, the plan has to treat it that way.

To the Appeals Department:
I am filing an internal appeal of the adverse benefit determination described above, in which the plan denied coverage for Dexcom G7. I am filing within the time allowed, and I am asking that the determination be reviewed by someone who was not involved in the original decision and who is not that person's subordinate.
Before this appeal is decided, please confirm which benefit this claim was processed under. This item can fall under either the pharmacy or the durable medical equipment benefit depending on the plan, and a claim assessed under the wrong one is denied without the request ever being judged on its merits. The enclosed records document my treatment regimen, testing frequency and recent results. If this device was covered previously and coverage has now stopped, I am asking you to state what changed, because my clinical circumstances have not.
Under the plan's obligations to me, I am requesting the following in writing, free of charge, and before this appeal is decided: 1. The specific reason for the denial and the plan provision or clinical criteria it relied on. 2. Copies of all documents, records and other information relevant to my claim, including any internal rule, guideline, protocol or criterion applied. 3. If the denial was based on medical necessity or on a determination that the treatment is experimental or investigational, an explanation of the scientific or clinical judgment applied to my circumstances. 4. The credentials of the reviewer who made the determination, and of the reviewer deciding this appeal.
Enclosed with this appeal: • Chart notes with the insulin regimen and testing frequency. • Documented hypoglycaemic episodes, especially any that required assistance. • Recent A1c results. • The prescriber's statement of why this specific device is required. • A copy of the denial notice I received.
Please confirm receipt of this appeal in writing, and provide the date by which a decision will be issued. If a delay in this decision would seriously jeopardise my health or my ability to regain maximum function, I am requesting that this appeal be handled on an expedited basis, on which a decision is due within 72 hours.
If this appeal is denied, I intend to request an independent external review, and I am asking that your decision letter include the instructions and the deadline for doing so.
Thank you for your attention to this appeal. I can be reached at [phone] or [email]. Sincerely, [Your signature] [Your printed name] [Member ID]
