R83-R89 — Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis
ICD-10-CM codes R83-R89 cover abnormal findings on examination of other body fluids, substances and tissues, without diagnosis, within symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified. The block holds 109 codes across 7 categories, of which 93 are billable and 16 are header codes that cannot be submitted on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- abnormal findings on antenatal screening of mother (O28.-)
- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
What else to watch in R83-R89
- 12 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
