Clinical Classification

Clinical Information

  • Medullary Sponge Kidney

    a non-hereditary kidney disorder characterized by the abnormally dilated (ectasia) medullary and inner papillary portions of the collecting ducts. these collecting ducts usually contain cysts or diverticula filled with jelly-like material or small calculi (kidney stones) leading to infections or obstruction. it should be distinguished from congenital or hereditary polycystic kidney diseases.
  • Nephrocystin-1|Juvenile Nephronophthisis 1 Protein|NPHP1

    nephrocystin-1 (732 aa, ~83 kda) is encoded by the human nphp1 gene. this protein is involved in the modulation of signaling.
  • Nephronophthisis

    progressive tubulointerstitial injury, inherited in an autosomal recessive pattern, caused by mutations in genes involved in ciliary function, which may result in an end stage renal failure.
  • Nephronophthisis 1|Familial Juvenile Nephronophthisis|Juvenile Nephronophthisis|NPH1

    progressive tubulointerstitial nephritis inherited in an autosomal recessive manner. it is caused by mutations in the nphp1 gene. patients present with anemia, polyuria, and polydipsia during childhood. the progressive bilateral kidney damage results in renal failure.
  • NPHP1 Gene|NPHP1|NPHP1|Nephronophthisis 1 (Juvenile) Gene

    this gene is involved in the mediation of signal transduction.
  • NPHP1 wt Allele|FLJ97602|JBTS4|NPH1|Nephronophthisis 1 (Juvenile) wt Allele|SLSN1

    human nphp1 wild-type allele is located in the vicinity of 2q13 and is approximately 83 kb in length. this allele, which encodes nephrocystin-1 protein, plays a role in the progression of adhesion-dependent signaling pathways. mutations in the gene are associated with familial juvenile nephronophthisis type 1, senior-loken syndrome type 1, and joubert syndrome type 4.
  • Medullary Sponge Kidney

    a developmental disorder of the kidney characterized by cystic dilatation of the medullary collecting ducts, resulting in a spongy gross appearance of the kidney. it may be asymptomatic or complicated by hematuria, infections, or renal stones.
  • Congenital Hepatic Fibrosis

    a congenital disorder usually inherited in an autosomal recessive pattern. it affects the hepatobiliary system and the kidneys. it is characterized by liver fibrosis, portal hypertension, and renal cysts.

Present on Admission (POA)

Q61.5 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Patient Education


Kidney Cysts

A cyst is a fluid-filled sac. You may get simple kidney cysts as you age; they are usually harmless. There are also some diseases which cause kidney cysts. One type is polycystic kidney disease (PKD). It runs in families. In PKD, many cysts grow in the kidneys. This can enlarge the kidneys and make them work poorly. About half of people with the most common type of PKD end up with kidney failure. PKD also causes cysts in other parts of the body, such as the liver.

Often, there are no symptoms at first. Later, symptoms include:

  • Pain in the back and lower sides
  • Headaches
  • Blood in the urine

Doctors diagnose PKD with imaging tests and family history. There is no cure. Treatments can help with symptoms and complications. They include medicines and lifestyle changes, and if there is kidney failure, dialysis or kidney transplants.

Acquired cystic kidney disease (ACKD) happens in people who have chronic kidney disease, especially if they are on dialysis. Unlike PKD, the kidneys are normal sized, and cysts do not form in other parts of the body. ACKD often has no symptoms. Usually, the cysts are harmless and do not need treatment. If they do cause complications, treatments include medicines, draining the cysts, or surgery.

Medullary cystic kidney disease type 1

Medullary cystic kidney disease type 1 (MCKD1) is an inherited condition that affects the kidneys. It leads to scarring (fibrosis) and impaired function of the kidneys, usually beginning in adulthood. The kidneys filter fluid and waste products from the body. They also reabsorb needed nutrients and release them back into the blood. As MCKD1 progresses, the kidneys are less able to function, resulting in kidney failure.

Declining kidney function in people with MCKD1 leads to the signs and symptoms of the condition. The features are variable, even among members of the same family. Many individuals with MCKD1 develop high blood pressure (hypertension), especially as kidney function worsens. Some develop high levels of a waste product called uric acid in the blood (hyperuricemia) because the damaged kidneys are unable to remove uric acid effectively. In a small number of affected individuals, the buildup of this waste product can cause gout, which is a form of arthritis resulting from uric acid crystals in the joints.

Although the condition is named medullary cystic kidney disease, only about 40 percent of affected individuals have medullary cysts, which are fluid filled pockets found in a particular region of the kidney. When present, the cysts are usually found in the inner part of the kidney (the medullary region) or the border between the inner and outer parts (corticomedullary region). These cysts are visible by tests such as ultrasound or CT scan.
