ICD-10 Code A52.75 – Syphilis of kidney and ureter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A52.75 – Syphilis of kidney and ureter
What it is
A52.75 identifies syphilitic infection involving the kidney and ureter. Use it when documentation specifies syphilis affecting these urinary structures, rather than a nonspecific genitourinary infection.
Clinical signs
Clinical features vary; refer to documentation. Findings may include urinary tract involvement attributed to syphilis, with renal or ureteral abnormalities noted by the clinician.
When to use this code
Use A52.75 when the provider documents syphilis of the kidney, ureter, or both. It is appropriate for confirmed or clearly stated syphilitic involvement of these organs in the assessment or final diagnosis.
Do not assign it for generic urinary symptoms, suspected infection, or kidney disease without a documented syphilis link. Check documentation if the record only mentions genitourinary syphilis or another renal condition.
Do not use for
Do not use for unspecified syphilis, renal infection, or ureteral disease without syphilitic etiology. Check documentation when the site or cause is not clearly stated.
Coding tip
Code A52.75 only when both the syphilis diagnosis and the kidney or ureter involvement are documented together.
