ICD-10 code for kidney late syphilis

The ICD-10-CM code for kidney late syphilis is A52.75 (Syphilis of kidney and ureter).

Within A52.7 (other symptomatic late syphilis), A52.75 is specifically for syphilis of kidney and ureter. Related codes cover late syphilitic oculopathy (A52.71), syphilis of lung and bronchus (A52.72), symptomatic late syphilis of other respiratory organs (A52.73), syphilis of liver and other viscera (A52.74), other genitourinary symptomatic late syphilis (A52.76), syphilis of bone and joint (A52.77), syphilis of other musculoskeletal tissue (A52.78) and other symptomatic late syphilis (A52.79).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 689 (Kidney and Urinary Tract Infections with MCC, relative weight 1.1415) and DRG 690 (Kidney and Urinary Tract Infections without MCC, relative weight 0.801), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
