Q61.4Renal dysplasia

Q61.4 is the ICD-10-CM diagnosis code for renal dysplasia. It belongs to category Q61 (cystic kidney disease), block Q60-Q64 (congenital malformations of the urinary system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q61 (cystic kidney disease), Q61.4 is specifically for renal dysplasia. Related codes cover congenital renal cyst (Q61.0), polycystic kidney, infantile type (Q61.1), polycystic kidney, adult type (Q61.2), polycystic kidney, unspecified (Q61.3), medullary cystic kidney (Q61.5), other cystic kidney diseases (Q61.8) and unspecified (Q61.9).

Don't report Q61.4 together with the conditions in its Excludes1 note: polycystic kidney disease (Q61.11-Q61.3).

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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), 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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 753.15 (renal dysplasia).
