Urology ICD-10-CM codes

BPH splits on symptoms: N40.0 without lower urinary tract symptoms and N40.1 with them. When reporting N40.1, add the codes for the specific LUTS the guidelines instruct you to identify, such as urinary frequency (R35.0), nocturia (R35.1), urinary retention (R33.9), and weak stream. This combination substantiates medical necessity for medication, urodynamics, and procedural workups.

Hematuria is coded by type: gross (R31.0), asymptomatic microscopic (R31.21), other microscopic (R31.29), and unspecified (R31.9). It stays on the claim as the reason for cystoscopy and imaging until a cause is established. Stone disease uses N20.0 for kidney calculus, N20.1 for ureteral calculus, and N13.30 for the resulting hydronephrosis when documented.

Prostate cancer work distinguishes active disease (C61) from surveillance after treatment: once therapy is complete and no disease remains, switch to Z85.46 (personal history of prostate cancer), with R97.20 for an elevated PSA finding. Z12.5 covers screening PSA encounters in asymptomatic men. Incontinence coding is type-specific and drives therapy choices: stress (N39.3), urge (N39.41), mixed (N39.46), overactive bladder (N32.81), and unspecified (R32) only when the type truly is not documented.
