Preparing for Surgery: Medicare Coverage and Billing Questions
Use a Medicare surgery checklist to ask about the facility, providers, prior authorization, cost estimates and covered care after discharge.
Before the procedure
Ask the Coverage Questions Alongside the Medical Questions
Your clinician explains why a procedure is recommended and the treatment options. The billing office and insurer explain how coverage applies. Keeping those conversations connected can help you understand costs without confusing a medical recommendation with an insurance approval.
This checklist is for planning scheduled care. For an urgent medical problem, follow emergency-care instructions rather than delaying care to complete a coverage checklist.
The setting
Where Will the Procedure Take Place?
Ask for the exact facility name and whether the planned care is inpatient, hospital outpatient or at an ambulatory surgical center. An overnight stay alone does not establish inpatient status. Different settings can produce different facility charges and Medicare cost sharing.
Read the inpatient, outpatient and observation guide. Ask whether the planned status could change and how you would be told. If there is a clinically appropriate choice of settings, request estimates for the actual locations under consideration.
The care team
Check More Than the Surgeon’s Name
- The surgeon and the exact practice location.
- The hospital or surgical facility.
- Anesthesia, assistant-surgeon, pathology and radiology services when relevant.
- Any required tests or imaging before the procedure.
- The providers or suppliers expected to help after discharge.
With Original Medicare, ask about Medicare participation and assignment. With Medicare Advantage, verify the exact plan network, service and location with the plan and provider. A hospital name in a directory does not answer every question about separately billing clinicians. Use the provider-network checklist.
Approval and documentation
Who Is Handling the Coverage Request?
Ask whether a referral, prior authorization or other coverage review is required and who will submit it. Request the authorization number, approved service, facility, dates and any conditions. Ask what to do if the procedure changes.
An approval must be read with the coverage conditions and eligibility in mind. If a request is denied, ask for the written decision and review options. The prior-authorization guide explains the general process.
Budget questions
Request an Estimate with Its Assumptions
| Ask | Why it matters |
|---|---|
| Does this include both facility and professional charges? | Different organizations may send separate bills. |
| Which deductible and cost-sharing amounts have already been met? | An estimate based on the wrong remaining deductible can mislead. |
| What does my supplement or other coverage pay? | Original Medicare’s share is not always the final amount you owe. |
| What might change the estimate? | Additional care or a different setting can change the bill. |
| What rehabilitation, prescriptions or equipment may follow? | The procedure is only one part of the episode. |
Keep the estimate and its date. It helps identify assumptions and discrepancies, but cannot guarantee the final cost of services that are not yet known.
Second opinions
Can Medicare Cover Another Surgical Opinion?
In some situations, Part B covers a second opinion for medically necessary, non-emergency surgery. Medicare also covers a third surgical opinion when the first two disagree. Applicable cost sharing remains. Ask the plan about its provider and coverage arrangements before scheduling.
The choice of treatment belongs in the conversation with your clinicians. Coverage research should help you ask informed questions, not tell you which operation to have.
After discharge
Plan the Next Stage Before You Leave
Ask what care, prescriptions, equipment or therapy is expected and which organizations will provide it. Check coverage requirements for each service; a surgery approval does not automatically authorize every later service. Use the home-health and equipment guide when arranging supplies.
Keep discharge instructions, provider contacts and claim notices together. If a caregiver is coordinating calls, arrange the appropriate permission early.
