Audiologists in O Fallon, MO

Most private insurance plans and Medicare Advantage plans cover diagnostic audiological evaluations, often with a physician referral. Medicare Part B covers diagnostic testing ordered by a physician but does not cover hearing aids. Coverage for hearing aids varies widely by plan. Always call your insurer before scheduling to confirm coverage and whether a referral is required. This is general information — not insurance or medical advice.

In most cases, no — audiologists in MO can be seen directly without a physician referral. However, some insurance plans require a referral for coverage of the evaluation. It's worth calling your insurer before scheduling if cost is a concern.

Start by taking the LSTN free hearing test — it gives you a baseline to share with your provider and helps you arrive knowing what questions to ask. Also bring: a list of current medications (some affect hearing), any prior audiograms, and a note on when you first started noticing changes and in what situations. Most appointments take 60–90 minutes.
