P71 is a non-billable ICD-10-CM category code for transitory neonatal disorders of calcium and magnesium metabolism, so it cannot be submitted on claims. Use a more specific code from this category instead, such as P71.0, P71.1, P71.2, and P71.3.

Specific Coding for Transitory neonatal disorders of calcium and magnesium metabOverview

Non-specific codes like P71 require more characters. Use one of these billable codes instead:

  • Use P71.0 for Cow's milk hypocalcemia in newborn

  • Use P71.1 for Other neonatal hypocalcemia

  • Use P71.2 for Neonatal hypomagnesemia

  • Use P71.3 for Neonatal tetany without calcium or magnesium deficiency

  • Use P71.4 for Transitory neonatal hypoparathyroidism

  • Use P71.8 for Other transitory neonatal disorders of calcium and magnesium metabolism

  • Use P71.9 for Transitory neonatal disorder of calcium and magnesium metabolism, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to P71: its own notes plus those printed at block P70-P74 and Chapter 16. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

From Block P70-P74 Transitory endocrine and metabolic disorders specific to newborn applies to 33 codes
  • transitory endocrine and metabolic disturbances caused by the infant's response to maternal endocrine and metabolic factors, or its adjustment to extrauterine environment
From Chapter 16 (P00-P96) Certain conditions originating in the perinatal period applies to 463 codes
  • conditions that have their origin in the fetal or perinatal period (before birth through the first 28 days after birth) even if morbidity occurs later

  • Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases
    transitory endocrine and metabolic disorders specific to newborn (P70-P74) names P70-P74, which includes this code

Excludes2 1

These codes carry an Excludes2 note naming P71: its condition is not part of those codes, and both may be reported when the patient has both.

  • P00 Newborn affected by maternal conditions that may be unrelated to present pregnancy
    newborn affected by maternal endocrine and metabolic disorders (P70-P74) names P70-P74, which includes this code

Patient EducationClinical

Metabolic Disorders

Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel.
