Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis (R83-R89) ICD-10-CM
The R83–R89 section covers abnormal findings on examination of other body fluids, substances and tissues, without diagnosis with 109 ICD-10-CM diagnosis codes, of which 93 are billable in fiscal year 2027. The section is organized into the 7 code ranges listed below.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the R83–R89 Code Range
These findings come from examining body fluids, substances, or tissue specimens when the finding has no diagnosis.
The categories separate findings by where the sample comes from: cerebrospinal fluid in R83, respiratory organs and the chest in R84, and digestive organs and the abdomen in R85. R86 and R87 separate specimens from male and female genital organs. R88 addresses other body fluids and substances, including cloudy dialysis effluent. R89 addresses specimens from other organs, systems, and tissues.
Within most categories, subdivisions distinguish abnormal levels of substances from findings involving immune responses, microorganisms, cells, or tissue. They also provide other and unspecified findings.
