Hyperphosphatemia ICD-10-CM codes | 2025

What ICD-10 Codes are used for Hyperphosphatemia?

Hyperphosphatemia is a clinical condition characterized by an elevated phosphate level in the blood. It is often associated with renal failure or disorders that affect calcium and phosphate homeostasis. The following ICD-10-CM codes, two of which are under section E83: Disorders of mineral metabolism, are integral to the diagnosis and billing process for hyperphosphatemia:

E83.39: Other disorders of phosphorus metabolism

This code is designated for conditions that result in abnormal phosphorus metabolism, including but not limited to hyperphosphatemia. Others include acid phosphatase deficiency, It is particularly useful when the condition is part of a broader metabolic disorder.

E83.30: Disorder of phosphorus metabolism, unspecified

Applied when there is a recognized phosphorus metabolism disorder, but the specific type is not documented. This code serves as a general category for phosphorus metabolism disorders.

E20.9: Hypoparathyroidism, unspecified

Hypoparathyroidism often leads to hyperphosphatemia due to the parathyroid gland hormone's role in phosphate regulation. This code is used when hypoparathyroidism is diagnosed, but the details are not specified.

N25.89: Other disorders resulting from impaired renal tubular function

Captures conditions related to renal tubular dysfunction, which can result in abnormal phosphate retention and hyperphosphatemia. It is particularly relevant in patients with chronic kidney disease.

Each of these codes plays a vital role in managing patients with hyperphosphatemia, from ensuring appropriate clinical care to facilitating accurate billing and coding for healthcare services provided.

Which Hyperphosphatemia ICD codes are billable?

All of the Hyperphosphatemia ICD-10 CM codes mentioned above are billable.

Clinical information

Hyperphosphatemia can occur due to various conditions and has potential complications if not managed properly. Here's a concise clinical overview:

• Often seen in patients with chronic kidney disease or acute kidney injury.
• Can be a result of excessive dietary intake or phosphate-containing laxatives.
• Underlying conditions such as metabolic acidosis, primary/secondary hyperparathyroidism, and kidney failure can lead to or contribute to hyperphosphatemia.
• May be asymptomatic in mild cases.
• Severe hyperphosphatemia can lead to muscle cramps, tetany, and cardiac arrhythmias.
• Treatment of the underlying cause is paramount.
• Dietary phosphate restriction and phosphate binders are commonly used.
• Dialysis may be required in cases associated with renal failure.

Synonyms include

• Elevated serum phosphate
• High blood phosphate level
• Phosphate toxicity
• Hyperphosphatemia in renal failure
• Secondary hyperphosphatemia
