Medicaid Coverage Through Humana Healthy Horizons
Humana’s Medicaid managed-care plan, Healthy Horizons, also covers the Dexcom G6, though the mechanics differ by state.
In South Carolina, both the Dexcom G6 and G7 are available at the pharmacy for Healthy Horizons members, and medications on the plan’s Comprehensive Drug List have carried no copay since July 2024.2Humana. Rx Newsletter
In Florida, Humana Healthy Horizons began allowing CGM supplies at both in-network pharmacies and DME providers on October 1, 2024. The Florida plan sets quantity limits on the G6: one receiver per year, three sensors per 30 days, and one transmitter per 90 days. Members who get an insulin pump through a DME provider must also get their CGM through DME, and members who get pump supplies at a pharmacy must get their CGM at a pharmacy.6Humana.

Who Qualifies
Humana Medicare Advantage plans must cover at least what Original Medicare covers, so the federal CGM eligibility rules apply. You need a diabetes diagnosis, and you must either use insulin or have a documented history of problematic hypoglycemia. A healthcare provider also has to determine that you or your caregiver have been trained to use the device.7Medicare.gov. Continuous Glucose Monitors
Insulin use is not strictly required. To qualify without insulin, your medical record must document either recurring episodes with blood glucose below 54 mg/dL along with prior medication adjustments, or at least one severe episode that required third-party assistance. To keep coverage going, you need an in-person or telehealth visit every six months to document that you’re using the device.8CMS. Local Coverage Article for CGMs, A52464
How To Get Your Dexcom G6 Supplies
Medicare Advantage members can order Dexcom supplies through a DME provider that accepts Medicare, or through a participating retail pharmacy. Humana points members toward two preferred DME providers:
- CCS Medical, 877-531-7959, Monday through Friday, 8 a.m. to 6 p.m. ET.
- Edwards Healthcare, 888-344-3434, Monday through Friday, 8:30 a.m. to 5 p.m. ET.
Both will coordinate with your prescribing provider to gather the clinical documentation needed for coverage. If you’re a new member, wait until your Humana ID card arrives before placing an order.1Humana. Continuous Glucose Monitors – Group Medicare Advantage
What the 2026 Discontinuation Means for You
Dexcom will stop manufacturing the G6 on July 1, 2026.3Dexcom. Dexcom G6 Transition Some supply may linger with pharmacies and distributors after that date, but availability is not guaranteed.9Dexcom. How Much Longer Will Dexcom G6 Be Available Dexcom recommends talking with your provider about moving to the G7 or G7 15 Day before the cutoff.
Coverage carries over. Dexcom states that insurance coverage for the G6 extends to the G7, and that every Medicare patient who uses insulin or has a history of severe hypoglycemia already has G7 coverage.3Dexcom. Dexcom G6 Transition Both the G7 and G7 15 Day are covered by Medicare and Medicare Advantage plans.10Dexcom. Dexcom G7 CGM System – Medicare Dexcom will keep supporting the G6 app and any unexpired G6 supplies within their warranty period.
If Humana Denies Your Claim
The most common denial reason for a CGM is a finding that the device is not medically necessary, which comes up most often for patients with type 2 diabetes or pre-diabetes.11Dexcom. Cost and Coverage Missing prior authorization, expired authorization, and coding errors are other frequent causes.
You have the right to appeal. The usual steps:
- Read the explanation of benefits and note the exact reason codes on the denial letter.
- Ask your treating or ordering physician to request a peer-to-peer review with Humana’s Clinical Review line, especially for medical-necessity denials.
- File a formal written appeal through Resolutions.Humana.com or by mail to Humana Grievances and Appeals, P.O. Box 14546, Lexington, KY 40512-4546. Include clinical records, a physician narrative, and references to the specific coverage policy criteria you meet.
- Request an independent external review if the internal appeal is unsuccessful.
Watch the deadlines. Medicare Advantage members have 65 calendar days from the denial date to file an appeal, and that federal deadline cannot be waived. Commercial plan members generally have 180 days.
