Insurance & Billing Help
The money side of testing is confusing by design. Here's a plain-language map of how lab billing works and where to get help when a bill doesn't look right.
- Every test is billed under a code (CPT code) — coverage often depends on whether the diagnosis code attached to it justifies the test to your insurer
- "Denied" doesn't always mean "not covered" — many denials are coding or paperwork issues that can be corrected and resubmitted
- You can ask the lab or clinic for an itemized bill — errors are common and you're entitled to see the codes
- Cash prices for labs are sometimes lower than the insurance rate — it's okay to ask both prices before the draw
- Patient advocates (for example, Medical Bill Gurus) specialize in fighting incorrect bills and denied claims on your behalf
- Appeals have deadlines — if you plan to dispute a denial, start sooner rather than later
Good to know
- This is general education, not billing, legal, or insurance advice — policies differ widely
- For a specific bill, an advocate or your insurer's member services line can address your exact situation
PRISM is for learning, not diagnosing. It explains what tests measure and how clinicians reason — it never tells you what to conclude, and it doesn't replace your doctor.
