Inclusion Terms
- Azotemic osteodystrophy
- Phosphate-losing tubular disorders
- Renal rickets
- Renal short stature
Type 2 Excludes
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.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Secondary Hyperparathyroidism
overproduction of parathyroid hormone in response to influence external to the parathyroid glands.
Patient EducationClinical
Bone Diseases
Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone.

Questions About N25.0Overview
Is N25.0 (Disorders resulting from impaired renal tubular function) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report renal osteodystrophy on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does N25.0 group to?
When renal osteodystrophy is the principal diagnosis on an inpatient stay, it groups to MS-DRG 698, 699, 700, with relative weights from 0.6899 to 1.6544 depending on complications. Higher weights mean higher Medicare reimbursement.
