Clinical Classification

Clinical Information

  • 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. (from adams et al., principles of neurology, 6th ed, p1490)
  • Nephrocalcinosis

    a condition characterized by calcification of the renal tissue itself. it is usually seen in distal renal tubular acidosis with calcium deposition in the distal kidney tubules and the surrounding interstitium. nephrocalcinosis causes renal insufficiency.
  • Tetany

    sudden and involuntary contraction of a muscle of group of muscles due to hypocalcemia.
  • Familial Primary Hypomagnesemia

    a hereditary disorder that leads to a selective defect in renal or intestinal magnesium absorption, resulting in a low serum magnesium concentration.
  • Grade 1 Hypomagnesemia, CTCAE|Grade 1 Hypomagnesemia

  • Grade 2 Hypomagnesemia, CTCAE|Grade 2 Hypomagnesemia

    <1.2-0.9 mg/dl; <0.5-0.4 mmol/l
  • Grade 3 Hypomagnesemia, CTCAE|Grade 3 Hypomagnesemia

    <0.9-0.7 mg/dl; <0.4-0.3 mmol/l
  • Grade 4 Hypomagnesemia, CTCAE|Grade 4 Hypomagnesemia

    <0.7 mg/dl; <0.3 mmol/l; life-threatening consequences
  • Grade 5 Hypomagnesemia, CTCAE|Grade 5 Hypomagnesemia

    death
  • Hypomagnesemia

    lower than normal levels of magnesium in the circulating blood.
  • Hypomagnesemia, CTCAE|Hypomagnesemia|Hypomagnesemia

    a disorder characterized by laboratory test results that indicate a low concentration of magnesium 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.
  • Nephrocalcinosis

    deposition of calcium in the renal parenchyma, resulting from high levels of calcium in the blood and/or urine.

Convert P71.2 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


Fluid and Electrolyte Balance

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help:

  • Balance the amount of water in your body
  • Balance your body's acid/base (pH) level
  • Move nutrients into your cells
  • Move wastes out of your cells
  • Make sure that your nerves, muscles, the heart, and the brain work the way they should

Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.

The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

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.
