ICD Coding
ICD-10-AM Code: Q61.2
Brief description
This is a genetic disorder of the kidney resulting in the development of multiple bilateral renal cysts, enlarged kidneys and renal damage.
Confirming the diagnosis
This diagnosis is based on imaging (MRI scan, CT scan or ultrasound of the kidneys), renal function testing, and genetic testing.
The relevant medical specialist is a nephrologist.
Additional diagnoses covered by SOP
ADPKD
Conditions not covered by SOP#
- acquired cystic disease of kidney
- autosomal recessive polycystic kidney disease
- medullary cystic kidney disease
- medullary sponge kidney disease

Clinical onset
The genetic abnormality is present from birth. The condition is typically asymptomatic early in life, with clinical manifestations typically appearing around the ages of 30 to 40 years.
Clinical worsening
The only SOP worsening factor is for inability to obtain appropriate clinical management. Natural progression of the disease varies with the phenotype. Worsening beyond the normal progression of the disease needs to be evident before a clinical worsening factor can be considered.
Treatment is aimed at slowing the rate of progression of kidney function loss and limiting complications. Measures include strict blood pressure control, dietary protein restriction, a low-salt diet, and statins.
In most patients, renal function remains intact until the fourth decade of life but once the glomerular filtration rate (GFR) starts to decline, the average reduction is 4.4 to 5.9 mL/min per year. Most patients with ADPKD die from cardiac causes or kidney failure.
