Clinical Information

• A group of genetic disorders of the kidney tubules characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic acidosis. Defective renal acidification of urine proximal tubules) or low renal acid excretion distal tubules) can lead to complications such as hypokalemia, hypercalcinuria with nephrolithiasis and nephrocalcinosis, and rickets.

• A rare disorder in which structures in the kidney that filter the blood are impaired, producing urine that is more acid than normal.

• Failure of the renal tubules of the kidney to excrete urine of normal acidity resulting in metabolic acidosis. It may lead to hypercalcinuria, nephrolithiasis, and renal failure. Causes include autoimmune disorders e.g., sjogren syndrome, systemic lupus erythematosus, and rheumatoid arthritis), medications e.g., non steroidal anti-inflammatory drugs, diuretics, and blood pressure medications), fanconi syndrome, or it may be familiar.

• Rare sometimes familial disorder of the renal tubule characterized by the inability to excrete urine of normal acidity; this leads to a hyperchloremic acidosis which is often associated with one or more secondary complications such as hypercalcinuria with nephrolithiasis and nephrocalcinosis, rickets, or osteomalacia and severe potassium depletion.

Details

• N25.89 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

• Short description: Oth disorders resulting from impaired renal tubular function

• The 2023 edition of ICD-10-CM N25.89 became effective on October 1, 2022.

• This is the American ICD-10-CM version of N25.89 – other international versions of ICD-10 N25.89 may differ.
