Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Cyst (multiple) (solitary) of kidney (acquired)

Type 1 Excludes

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.

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
