Code Classification

  • Certain conditions originating in the perinatal period
    (P00–P96)
    • Transitory endocrine and metabolic disorders specific to newborn
      (P70-P74)
      • Other transitory neonatal electrolyte and metabolic disturbances
        (P74)

P74.31 is a billable diagnosis code used to specify a medical diagnosis of hyperkalemia of newborn. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Hyperkalemia
  • Transitory neonatal electrolyte disturbance
  • Transitory neonatal hyperkalemia

Clinical Classification

Clinical Information

  • Hyperkalemia

    abnormally high potassium concentration in the blood, most often due to defective renal excretion. it is characterized clinically by electrocardiographic abnormalities (elevated t waves and depressed p waves, and eventually by atrial asystole). in severe cases, weakness and flaccid paralysis may occur. (dorland, 27th ed)

  • Pseudohypoaldosteronism

    a heterogeneous group of disorders characterized by renal electrolyte transport dysfunctions. congenital forms are rare autosomal disorders characterized by neonatal hypertension, hyperkalemia, increased renin activity and aldosterone concentration. the type i features hyperkalemia with sodium wasting; type ii, hyperkalemia without sodium wasting. pseudohypoaldosteronism can be the result of a defective renal electrolyte transport protein or acquired after kidney transplantation.

  • Grade 1 Hyperkalemia, CTCAE|Grade 1 Hyperkalemia

    >uln-5.5 mmol/l

  • Grade 2 Hyperkalemia, CTCAE|Grade 2 Hyperkalemia

    >5.5-6.0 mmol/l; intervention initiated

  • Grade 3 Hyperkalemia, CTCAE|Grade 3 Hyperkalemia

    >6.0-7.0 mmol/l; hospitalization indicated

  • Grade 4 Hyperkalemia, CTCAE|Grade 4 Hyperkalemia

    >7.0 mmol/l; life-threatening consequences

  • Grade 5 Hyperkalemia, CTCAE|Grade 5 Hyperkalemia

    death

  • Hyperkalemia

    higher than normal levels of potassium in the circulating blood; associated with kidney failure or sometimes with the use of diuretic drugs.

  • Hyperkalemia, CTCAE|Hyperkalemia|Hyperkalemia

    a disorder characterized by laboratory test results that indicate an elevation in the concentration of potassium in the blood; associated with kidney failure or sometimes with the use of diuretic drugs.

  • Hyperkalemic Mineralocorticoid Resistance|Chloride Shunt Syndrome|Familial Hyperkalemic Hypertension|Gordon Hyperkalemia|Mineralocorticoid Resistant Hyperkalemia|PHA Type 2|Pseudohypoaldosteronism, Type II|Spitzer-Weinstein Syndrome

    a genetically heterogynous condition characterized by hyperkalemia, hyperchloremic acidosis, low or suppressed renin activity, and normal to high concentrations of aldosterone. mutations in genes (for example wnk1 or wnk4), regulating na-cl cotransporters (ncc), na-k-cl cotransporters (nkcc2), or the renal outer medullary potassium (romk) channel have been identified as causative in this condition. the primary abnormality is thought to be a specific defect of the renal secretory mechanism for potassium, which limits the kaliuretic response to, but not the sodium and chloride reabsorptive effect of, mineralocorticoid.

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.

Potassium

Potassium is a mineral that your body needs to work properly. It is a type of electrolyte. It helps your nerves to function and muscles to contract. It helps your heartbeat stay regular. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium's harmful effects on blood pressure.

Many people get all the potassium they need from what they eat and drink. Sources of potassium in the diet include:

  • Leafy greens, such as spinach and collards
  • Fruit from vines, such as grapes and blackberries
  • Root vegetables, such as carrots and potatoes
  • Citrus fruits, such as oranges and grapefruit

Your kidneys help to keep the right amount of potassium in your body. If you have chronic kidney disease, your kidneys may not remove extra potassium from the blood. Some medicines also can raise your potassium level. You may need a special diet to lower the amount of potassium that you eat.

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.
