About coding hypoglycemic syndrome
The ICD-10-CM code for hypoglycemic syndrome is E16.2 (Hypoglycemia, unspecified).
Within E16, choose E16.2 (Hypoglycemia, unspecified) only when documentation doesn't support a more specific option: drug-induced hypoglycemia without coma (E16.0), other hypoglycemia (E16.1), increased secretion of glucagon (E16.3), increased secretion of gastrin (E16.4), other specified disorders of pancreatic internal secretion (E16.8), disorder of pancreatic internal secretion, unspecified (E16.9) and hypoglycemia level (E16.A).
Don't report E16.2 together with the conditions in its Excludes1 note: diabetes with hypoglycemia (E08.649, E10.649, E11.649, E13.649).
Use an additional code for hypoglycemia level, if applicable (E16.A-).
Don't confuse with (Excludes1 for E16.2)
