What This Code Means
A52.75 is the ICD-10-CM diagnosis code for syphilis of kidney and ureter. This code describes syphilis infection that has spread to the kidneys and ureters (the tubes that carry urine from the kidneys to the bladder). This is a late-stage complication of untreated syphilis affecting the urinary system. A52.75 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).
A52.75 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify the stage of syphilis in the medical record, as this code specifically indicates late syphilis with renal involvement; ensure documentation supports urinary tract involvement rather than other organ systems.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A52.75 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify the stage of syphilis in the medical record, as this code specifically indicates late syphilis with renal involvement; ensure documentation supports urinary tract involvement rather than other organ systems
- •This code should be used alongside the primary syphilis diagnosis code (A52) and may require additional codes for any resulting kidney dysfunction or urinary complications
