Code Classification

  • Endocrine, nutritional and metabolic diseases
    (E00–E89)
    • Metabolic disorders
      (E70-E88)
      • Other disorders of fluid, electrolyte and acid-base balance
        (E87)

E87.20 is a billable diagnosis code used to specify a medical diagnosis of acidosis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like E87.20 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Acidosis

    a pathologic condition of acid accumulation or depletion of base in the body. the two main types are respiratory acidosis and metabolic acidosis, due to metabolic acid build up.
  • Acidosis, Lactic

    acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. it may occur spontaneously or in association with diseases such as diabetes mellitus; leukemia; or liver failure.
  • Acidosis, Renal Tubular

    a group of genetic disorders of the kidney tubules characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic acidosis. defective renal acidification of urine (proximal tubules) or low renal acid excretion (distal tubules) can lead to complications such as hypokalemia, hypercalcinuria with nephrolithiasis and nephrocalcinosis, and rickets.
  • Acidosis, Respiratory

    respiratory retention of carbon dioxide. it may be chronic or acute.
  • Diabetic Ketoacidosis

    a life-threatening complication of diabetes mellitus, primarily of type 1 diabetes mellitus with severe insulin deficiency and extreme hyperglycemia. it is characterized by ketosis; dehydration; and depressed consciousness leading to coma.
  • Hypoaldosteronism

    a congenital or acquired condition of insufficient production of aldosterone by the adrenal cortex leading to diminished aldosterone-mediated synthesis of na(+)-k(+)-exchanging atpase in renal tubular cells. clinical symptoms include hyperkalemia, sodium-wasting, hypotension, and sometimes metabolic acidosis.
  • 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.
  • Hydrops Fetalis

    abnormal accumulation of serous fluid in two or more fetal compartments, such as skin; pleura; pericardium; placenta; peritoneum; amniotic fluid. general fetal edema may be of non-immunologic origin, or of immunologic origin as in the case of erythroblastosis fetalis.
  • Acidosis

    an abnormally high acidity of the blood and other body tissues. acidosis can be either respiratory or metabolic.
  • Acidosis

    an abnormally high acidity (excess hydrogen-ion concentration) of the blood and other body tissues.
  • Acidosis, CTCAE|Acidosis|Acidosis

    a disorder characterized by abnormally high acidity (high hydrogen-ion concentration) of the blood and other body tissues.
  • Autosomal Recessive Distal Renal Tubular Acidosis-4 with Hemolytic Anemia|DRTA4

    an autosomal recessive type of distal renal tubular acidosis caused by mutation(s) in the slc4a1 gene, encoding band 3 anion transport protein. additionally, it may be characterized by hemolytic anemia.
  • Diabetes Mellitus due to Underlying Condition with Ketoacidosis with Coma|Diabetes mellitus due to underlying condition with ketoacidosis with coma

    the metabolic condition resulted from uncontrolled diabetes mellitus, in which the shift of acid-base status of the body toward the acid side because of loss of base or retention of acids other than carbonic acid is accompanied by the accumulation of ketone bodies in body tissues and fluids.
  • Distal Renal Tubular Acidosis

    failure of the renal tubules of the kidney to excrete urine of sufficient acidity, resulting in metabolic acidosis.
  • Drug or Chemical Induced Diabetes Mellitus with Ketoacidosis with Coma|Drug or chemical induced diabetes mellitus with ketoacidosis with coma

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.
