Transitory neonatal disorders of calcium and magnesium metabolism (P71)

ICD-10 code section P71 covers transitory neonatal disorders related to calcium and magnesium metabolism. These codes are used to identify short-term metabolic issues affecting newborns' calcium and magnesium levels, crucial for early diagnosis and treatment.

This section includes specific conditions like P71.0 for cow's milk hypocalcemia, also called neonatal hypocalcemia, which occurs when a newborn experiences low calcium due to milk intake. P71.1 captures other types of neonatal hypocalcemia, including late-onset or phosphate-related causes. For low magnesium conditions, P71.2 addresses neonatal hypomagnesemia, which is linked with various familial syndromes and tetany. P71.3 codes neonatal tetany when calcium and magnesium levels are normal, indicating muscle spasms without deficiency. P71.4 records transient neonatal hypoparathyroidism, a temporary hormone deficiency affecting calcium regulation. Other less common metabolic disorders fall under P71.8, and unspecified cases fit P71.9. Using these codes helps clinicians and coders accurately identify and document neonatal calcium and magnesium metabolic disorders for effective management and billing.

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.

Hypocalcemia

Reduction of the blood calcium below normal. Manifestations include hyperactive deep tendon reflexes, Chvostek's sign, muscle and abdominal cramps, and carpopedal spasm. (Dorland, 27th ed)

Hypoparathyroidism

A condition caused by a deficiency of PARATHYROID HORMONE (or PTH). It is characterized by HYPOCALCEMIA and hyperphosphatemia. Hypocalcemia leads to TETANY. The acquired form is due to removal or injuries to the PARATHYROID GLANDS. The congenital form is due to mutations of genes, such as TBX1; (see DIGEORGE SYNDROME); CASR encoding CALCIUM-SENSING RECEPTOR; or PTH encoding parathyroid hormone.

Tetany

A disorder characterized by muscle twitches, cramps, and carpopedal spasm, and when severe, laryngospasm and seizures. This condition is associated with unstable depolarization of axonal membranes, primarily in the peripheral nervous system. Tetany usually results from HYPOCALCEMIA or reduced serum levels of MAGNESIUM that may be associated with HYPERVENTILATION; HYPOPARATHYROIDISM; RICKETS; UREMIA; or other conditions.
