Social Security & Medicare

Here’s from the Aetna documents, page 14:

There is no coinsurance, copayment, or deductible for pneumonia, influenza, Hepatitis B and Covid-19 vaccines.

This is covered under Medicare part B. I think the doctor’s office charged it to Medicare part D - prescription drug benefit.

From the Medicare 2023 document:

Preventive Services
Flu shots
Medicare covers the seasonal flu shot (or vaccine). You pay nothing for the flu shot if the doctor or other qualified health care provider accepts assignment for giving the shot.

Preventive Service’Pneumococcal shots
Medicare covers pneumococcal shots (or vaccines) to help prevent pneumococcal infections (like certain types of pneumonia). Etc etc etc.
