About R80

R80 is the ICD-10-CM diagnosis code for proteinuria. It belongs to block R80-R82 (abnormal findings on examination of urine, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R80.0 (proteinuria), R80.1 (unspecified), R80.2 (unspecified), R80.3 (proteinuria), R80.8 (proteinuria) and R80.9 (unspecified).

Don't report R80 together with the conditions in its Excludes1 note: gestational proteinuria (O12.1-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
