A plan can look attractive on paper and still be a poor fit for the care you use. Make your provider and medication list before comparing plans. Then verify each important item against the exact plan and coverage year.
Start with specific providers
For Original Medicare, ask whether the provider accepts Medicare and accepts assignment. For Medicare Advantage, ask whether the provider participates in the exact plan, not just the insurance company’s brand. A practice may participate in one network and not another.
Check both the plan directory and the provider’s office. Record the date, the person you spoke with and the exact plan name. If answers conflict, resolve them with the plan before relying on the provider’s availability.
Check more than your primary doctor
- Specialists and the office location you actually visit.
- Preferred hospital and outpatient surgery center.
- Laboratory, imaging and therapy providers.
- Medical equipment suppliers.
- Dialysis, infusion or other ongoing treatment facilities.
Ask about referrals, authorizations and planned out-of-area care. A covered service can still require a particular approval or network arrangement. Emergency access rules do not make every planned out-of-network appointment equivalent to in-network care.
Use an exact medicine list
Include drug name, brand or generic, strength, dosage form, quantity and frequency. Check formulary status, tier, prior authorization, step therapy and quantity limits. A covered name at the wrong strength is not a completed check. Ask your prescriber about clinical alternatives rather than changing medication yourself.
Price the pharmacy you will use
Preferred and other network pharmacies can have different cost sharing. Compare a realistic refill pattern across the year, including any deductible. If mail order is part of an estimate, make sure you are comfortable using it and that the medicine is available that way.
Keep a verification sheet
| Item | Question to answer |
|---|---|
| Provider | Exact plan accepted at my location? |
| Service | Referral, authorization or setting requirement? |
| Prescription | Exact drug and quantity covered, with what restrictions? |
| Pharmacy | Network status and estimated refill cost? |
| Evidence | Who confirmed it, and when? |
Common question: Is one verification permanent? No. Networks, formularies and your needs can change. Repeat the review when considering a new plan and during your yearly coverage check.
