Q61.9 — Cystic kidney disease, unspecified
Is Q61.9 billable?
Yes, but Q61.9 is an unspecified code. Q61.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Q61.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Q61.9 — the more specific alternatives are listed below.

Which MS-DRGs does Q61.9 group to?
Q61.9 sits in MDC 11 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 698Other Kidney and Urinary Tract Diagnoses with MCCmedical
- 699Other Kidney and Urinary Tract Diagnoses with CCmedical
- 700Other Kidney and Urinary Tract Diagnoses without CC/MCCmedical
As a secondary diagnosis, Q61.9 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

- Meckel-Gruber syndrome
Excludes1 — never code together — inherited from Q61
The conditions below can never be reported together with Q61.9 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 17
The conditions below are not part of Q61.9, but a patient may have both at the same time. When documentation supports it, Q61.9 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
