Does Understood Care work with Medicare patients?

Yes. Understood Care focuses on Medicare patients and their families, with advocates who understand Medicare, Medicare Advantage, care coordination, coverage rules, billing issues, and appeal pathways.

Will I have a dedicated patient advocate?

Yes. This is Understood Care's first commitment: One Advocate, For Life. Every patient is matched at intake with one dedicated patient advocate and given that advocate's personal phone number, email, and text. Patients do not go into a call queue. The assignment is permanent: even after Understood Care has completed all tasks for a patient, they keep the same advocate. If a patient needs us again six months later, they will still have the same advocate.

How often will my Understood Care advocate communicate with me?

Understood Care follows a frequent-communication procedure with both active and follow-up patients. While the advocate is actively working on a patient's case, they communicate every 7 days by phone, text, or email with progress information. Once the patient has been helped with everything they needed, the case moves to a follow-up cadence: the advocate still checks in every month.

Does Understood Care use AI?

Yes. Understood Care is AI-supported. AI tools help every advocate surface programs, benefits, and services tied to where the patient lives, with the most up-to-date eligibility information. The result is that patients and advocates get the resources they need faster, while the human advocate stays in the loop on every patient's case.

Statewide, 46.1% of beneficiaries chose Medicare Advantage in 2025, a little below the national average. Counties above that line see more prior authorizations and more denials worth appealing; counties below it lean on Medigap rights, which in South Carolina mean no birthday rule and, for under-65 disability beneficiaries, only the South Carolina Health Insurance Pool's limited Plans A, C, and D, on top of the standard six-month Open Enrollment Period at 65 with Part B. About 10.7% of South Carolina seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help and South Carolina's Medicare Savings Programs (which keep an income and asset test). South Carolina has no state pharmaceutical assistance program, so Extra Help is the drug-cost help to claim, and because the state has not expanded Medicaid, screening for every program that does exist matters more. For the full rundown, sources included, see our South Carolina patient advocacy hub.
