Which MS-DRGs does N20.2 group to?
N20.2 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.
- 693Urinary Stones with MCCmedical
- 694Urinary Stones without MCCmedical
As a secondary diagnosis, N20.2 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from N20
The conditions below can never be reported together with N20.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N20.2, but a patient may have both at the same time. When documentation supports it, N20.2 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)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has N20.2 existed?
