Cystic kidney disease (Q61) ICD-10-CM
The Q61 code range covers cystic kidney disease with 14 ICD-10-CM diagnosis codes. 11 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q61 range.
Kidney Diseases, Cystic
A heterogeneous group of hereditary and acquired disorders in which the KIDNEY contains one or more CYSTS unilaterally or bilaterally (KIDNEY, CYSTIC).
Multicystic Dysplastic Kidney
A nongenetic defect due to malformation of the KIDNEY which appears as a bunch of grapes with multiple renal cysts but lacking the normal renal bean shape, and the collection drainage system. This condition can be detected in-utero with ULTRASONOGRAPHY.
About the Q61 Code Range
Cystic kidney disease means that one or both kidneys contain one or more cysts. This category sits within congenital malformations of the urinary system.
Q61.0 covers congenital kidney cysts, with subdivisions for a single cyst, multiple cysts, or an unspecified number. Polycystic kidney is separated into infantile type Q61.1, adult type Q61.2, and unspecified type Q61.3. The infantile type further separates cystic dilatation of collecting ducts from other infantile types.
Other categories identify renal dysplasia Q61.4, medullary cystic kidney Q61.5, other cystic kidney diseases, and unspecified cystic kidney disease.
