Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Positive culture findings of urine

Excludes1 inherited from the categories above R82.79

These are not written on R82.79, but they bind it: a note on a category applies to every code beneath it. Billing R82.79 with anything listed here is a denial.

Written on R82.7 — Abnormal findings on microbiological examination of urine

colonization status (Z22.-)

Excludes2 inherited from the categories above R82.79

Also inherited, and the opposite of Excludes1: these conditions are not part of R82.79, but a patient can have both, so you may code both.

Written on R82 — Other and unspecified abnormal findings in urine

hematuria (R31.-)

Risk adjustment

R82.79 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
