N27.9: Small kidney of unknown cause, unspecified

Your kidney is smaller than normal.

There are normally 2 kidneys in the body. They filter blood and create urine. They thus help to detoxify the body. Furthermore, the kidneys regulate the blood pressure and salt content in the blood, among other things.

It’s not clear why your kidney is smaller than normal. The kidney may no longer work properly as a result. If just one kidney stops working properly, the healthy kidney can often take over completely.

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
  • B: Both sides
