E16.2 is a billable diagnosis code used to specify a medical diagnosis of hypoglycemia, 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 E16.2 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.

Approximate Synonyms

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

  • Adult onset non-insulinoma persistent hyperinsulinemic hypoglycemia

  • Glucose level below reference range
  • Glycopenia
  • Hypoglycemia
  • Hypoglycemia-induced convulsion
  • Hypoglycemic disorder
  • Hypoglycemic encephalopathy
  • Hypoglycemic shock
  • Hypoglycemic syndrome
  • Neuropathy associated with hypoglycemia
  • Nocturnal hypoglycemia due to diabetes mellitus
  • Non-diabetic hypoglycemia
  • Non-diabetic hypoglycemia
  • Random blood glucose outside reference range
  • Random blood sugar below reference range
  • Random glucose level abnormal
  • Sequelae of endocrine disorders
  • Situation-related seizures
  • Spontaneous hypoglycemia

Clinical Information

  • Congenital Hyperinsulinism-. a familial, nontransient hypoglycemia with defects in negative feedback of glucose-regulated insulin release. clinical phenotypes include hypoglycemia; hyperinsulinemia; seizures; coma; and often large birth weight. several sub-types exist with the most common, type 1, associated with mutations on an atp-binding cassette transporters (subfamily c, member 8).
  • Hypoglycemia-. a syndrome of abnormally low blood glucose level. clinical hypoglycemia has diverse etiologies. severe hypoglycemia eventually lead to glucose deprivation of the central nervous system resulting in hunger; sweating; paresthesia; impaired mental function; seizures; coma; and even death.

Tabular List of Diseases and Injuries

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.
