Code Classification

  • Certain conditions originating in the perinatal period
    (P00–P96)
    • Transitory endocrine and metabolic disorders specific to newborn
      (P70-P74)
      • Transitory neonatal disorders of calcium and magnesium metabolism
        (P71)

P71.1 is a billable diagnosis code used to specify a medical diagnosis of other neonatal hypocalcemia. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Clinical Classification

Clinical Information

  • 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)

  • Familial Hypercalciuric Hypocalcemia

    a hereditary condition caused by calcium sensing receptor gene mutations, resulting in calcium-hypersensitivity, and compensatory hypocalcemia and hypercalciuria.

  • Grade 1 Hypocalcemia, CTCAE|Grade 1 Hypocalcemia

    corrected serum calcium of

  • Grade 2 Hypocalcemia, CTCAE|Grade 2 Hypocalcemia

    corrected serum calcium of <8.0-7.0 mg/dl; <2.0-1.75 mmol/l; ionized calcium <1.0-0.9 mmol/l; symptomatic

  • Grade 3 Hypocalcemia, CTCAE|Grade 3 Hypocalcemia

    corrected serum calcium of <7.0-6.0 mg/dl; <1.75-1.5 mmol/l; ionized calcium <0.9-0.8 mmol/l; hospitalization indicated

  • Grade 4 Hypocalcemia, CTCAE|Grade 4 Hypocalcemia

    corrected serum calcium of <6.0 mg/dl; <1.5 mmol/l; ionized calcium <0.8 mmol/l; life-threatening consequences

  • Grade 5 Hypocalcemia, CTCAE|Grade 5 Hypocalcemia

    death

  • Hypocalcemia

    lower than normal levels of calcium in the circulating blood.

  • Hypocalcemia, CTCAE|Hypocalcemia|Hypocalcemia

    a disorder characterized by laboratory test results that indicate a low concentration of calcium (corrected for albumin) in the blood.

  • TRPM6 wt Allele|CHAK2|FLJ22628|HMGX|HOMG|HOMG1|HSH|Hypomagnesemia, Secondary Hypocalcemia Gene|Transient Receptor Potential Cation Channel Subfamily M Member 6 wt Allele|Transient Receptor Potential Cation Channel, Subfamily M, Member 6 Gene

    human trpm6 wild-type allele is located in the vicinity of 9q21.13 and is approximately 166 kb in length. this allele, which encodes transient receptor potential cation channel subfamily m member 6 protein, is involved in both magnesium homeostasis and protein phosphorylation. mutation of the gene is associated with hypomagnesemia.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • neonatal hypoparathyroidism P71.4

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert P71.1 to ICD-9-CM

  • ICD-9-CM Code: 775.4 - Hypocalcem/hypomagnes NB
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Calcium

You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99% of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.

It is important to get plenty of calcium in the foods you eat. Foods rich in calcium include:

  • Dairy products such as milk, cheese, and yogurt
  • Leafy, green vegetables
  • Fish with soft bones that you eat, such as canned sardines and salmon
  • Calcium-enriched foods such as breakfast cereals, fruit juices, soy and rice drinks, and tofu. Check the product labels.

The exact amount of calcium you need depends on your age and other factors. Growing children and teenagers need more calcium than young adults. Older women need plenty of calcium to prevent osteoporosis. People who do not eat enough high-calcium foods should take a calcium supplement.

Uncommon Infant and Newborn Problems

It can be scary when your baby is sick, especially when it is not an everyday problem like a cold or a fever. You may not know whether the problem is serious or how to treat it. If you have concerns about your baby's health, call your health care provider right away.

Learning information about your baby's condition can help ease your worry. Do not be afraid to ask questions about your baby's care. By working together with your health care provider, you make sure that your baby gets the best care possible.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
