Oth diabetes mellitus with ketoacidosis without coma

This code signifies a form of diabetes mellitus, other than Type 1 or Type 2, that is complicated by diabetic ketoacidosis (DKA) but without an associated comatose state. This condition is characterized by high blood sugar, dehydration, and the presence of ketones due to insufficient insulin.

Apply this code when documentation specifies "other specified diabetes mellitus" (e.g., secondary diabetes due to pancreatectomy, drug-induced diabetes) and explicitly states the presence of ketoacidosis without coma. Supporting documentation should include laboratory findings confirming DKA (e.g., elevated blood glucose, positive ketones in urine/blood, metabolic acidosis) and a clear diagnosis of the underlying diabetes type.

• Always ensure the physician explicitly documents "ketoacidosis" and clarifies the absence of coma.
• Do not use this code for Type 1 or Type 2 diabetes with ketoacidosis; specific codes exist for those scenarios.
• Sequence this code as the principal diagnosis when the ketoacidosis is the primary reason for the encounter.
