Which MS-DRGs does N39.0 group to?
N39.0 sits in MDC 11 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 689Kidney and Urinary Tract Infections with MCCmedical
- 690Kidney and Urinary Tract Infections without MCCmedical
As a secondary diagnosis, N39.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 06.
How is N39.0 listed in the Alphabetic Index?

Excludes1 — never code together
The conditions below can never be reported together with N39.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code
Report an additional code alongside N39.0 to fully describe the condition. N39.0 is sequenced first.
- code (B95-B97), to identify infectious agent.
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N39.0, but a patient may have both at the same time. When documentation supports it, N39.0 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
