Disorders resulting from impaired renal tubular function (N25)
The ICD-10 code N25 covers disorders arising from impaired renal tubular function, which affect the kidney’s ability to handle essential substances. This section includes specific codes for conditions like renal osteodystrophy (N25.0) and nephrogenic diabetes insipidus (N25.1), providing precise coding options for these renal tubular-related diseases.
The ICD-10 code for renal osteodystrophy (N25.0) addresses kidney-related bone disorders caused by abnormal mineral and bone metabolism, often linked to chronic kidney disease and secondary hyperparathyroidism. This condition is also known by several synonymous terms including Sagliker syndrome and chronic kidney disease mineral and bone disorder, helping healthcare providers select the correct code when coding for these presentations. N25.1 identifies nephrogenic diabetes insipidus, a condition characterized by resistance to vasopressin and resultant excessive urination, with synonyms such as hereditary vasopressin resistance aiding in accurate code assignment. Codes like N25.81 specify secondary hyperparathyroidism of renal origin, while N25.89 and N25.9 cover other and unspecified disorders caused by renal tubular impairment, including various tubular acidoses and inherited tubulopathies. Using these detailed codes ensures proper documentation and tracking of renal tubular dysfunctions in clinical practice.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Azotemia
A biochemical abnormality referring to an elevation of BLOOD UREA NITROGEN and CREATININE. Azotemia can be produced by KIDNEY DISEASES or other extrarenal disorders. When azotemia becomes associated with a constellation of clinical signs, it is termed UREMIA.
Gitelman Syndrome
An inherited renal disorder characterized by defective NaCl reabsorption in the convoluted DISTAL KIDNEY TUBULE leading to HYPOKALEMIA. In contrast with BARTTER SYNDROME, Gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria, and is caused by mutations in the thiazide-sensitive SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
