About E13.64

E13.64 is the ICD-10-CM diagnosis code for other specified diabetes mellitus with hypoglycemia. It belongs to category E13 (other specified diabetes mellitus), block E08-E13 (diabetes mellitus) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within E13.6 (other specified diabetes mellitus with other specified complications), E13.64 is specifically for other specified diabetes mellitus with hypoglycemia. Related codes cover diabetic arthropathy (E13.61), skin complications (E13.62), oral complications (E13.63), hyperglycemia (E13.65) and other specified complication (E13.69).

To report this condition, pick the subcode that matches the documentation: E13.641 (with coma) and E13.649 (without coma).

Use an additional code for hypoglycemia level, if applicable (E16.A-). Use an additional code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85), insulin (Z79.4), oral antidiabetic drugs (Z79.84) and oral hypoglycemic drugs (Z79.84).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
