What this code covers
Source · Editorial summary grounded in 3 cited references ↓
A sed rate done by hand is 85651, usually a Westergren tube read at one hour. Ortho uses ESR constantly: suspected septic joint, osteomyelitis, periprosthetic joint infection, spine infection, and following inflammatory arthritis. It is almost always paired with CRP.
The code choice depends on the method. Manual ESR is 85651. Automated is 85652. Bill one or the other, never both for the same sample. Manual ESR is a CLIA-waived test, so an office with a certificate of waiver can run it. It is also one of the few waived codes CMS does not require QW on, so leave the modifier off.
Payers expect an inflammatory or infectious concern in the diagnosis: a painful arthroplasty, fever after surgery, a red hot joint, or a known inflammatory arthritis. Serial ESRs during antibiotic treatment are covered when the notes show they are guiding care, but daily repeats without a change in plan get questioned.
