251.2
ICD-9-CMThis code represents a general diagnosis of low blood glucose levels without further specification of its cause or type. It indicates a symptomatic or biochemically confirmed state of hypoglycemia where the underlying etiology is either unknown, not yet determined, or not documented.
Use this code when documentation clearly states "hypoglycemia, unspecified" or "hypoglycemia NOS." It is appropriate for initial presentations of hypoglycemia before a definitive cause (e.g., drug-induced, post-surgical, reactive) has been identified or when the physician explicitly states the cause is unknown.
