  • N25.0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2021 edition of ICD-10-CM N25.0 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of N25.0 - other international versions of ICD-10 N25.0 may differ.

  • Renal rickets
  • Renal short stature
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (N25.0) and the excluded code together.

    Other disorders of kidney and ureter

    Type 2 Excludes
    • disorders of kidney and ureter with urolithiasis (N20-N23)
    Other disorders of kidney and ureter
Clinical Information
  • Decalcification of bone or abnormal bone development due to chronic kidney diseases, in which 1,25-dihydroxyvitamin d3 synthesis by the kidneys is impaired, leading to reduced negative feedback on parathyroid hormone. The resulting secondary hyperparathyroidism eventually leads to bone disorders.
  • Metabolic bone disease due to increased bone resorption resulting from the acidosis and secondary hyperparathyroidism of renal insufficiency.
