CPT code 87635
What does CPT code 87635 mean on a medical bill?
This is the lab-run COVID test, the one processed by a machine rather than the strip that gives an answer in minutes. The rapid version is a different code. Some emergency rooms run both from the same swab and bill both, so check your results: if only one result exists, only one test should be charged. Coverage rules for this test have changed over the years, so also check what your plan applied.
What should I watch out for with CPT code 87635?
- Both a rapid test and a lab-run test billed with only one result in your record
- A test billed by an outside lab company you never heard of, weeks after the visit
- Cost sharing applied in a way your plan documents do not describe — worth calling your insurer about
