Drug/chem diab w hyprosm w/o nonket hyprgly-hypros coma

This code signifies diabetes mellitus that has been directly caused by a drug or chemical substance, presenting with a state of hyperosmolarity. Importantly, this condition does not involve the severe complication of nonketotic hyperglycemic-hyperosmolar coma (NKHHC). It represents a metabolic derangement induced by an exogenous agent, leading to elevated blood glucose and increased serum osmolality.

Use this code when documentation clearly indicates that diabetes mellitus and hyperosmolarity are a direct consequence of a prescribed medication, illicit drug, or chemical exposure. This applies to patients experiencing significant hyperglycemia and dehydration without evidence of ketoacidosis or progression to a comatose state. Supporting documentation should identify the causative drug or chemical.

• Always code the specific drug or chemical causing the diabetes as an adverse effect (T36-T65 with 5th or 6th character 5) or poisoning (T36-T65 with 5th or 6th character 1-4) in addition to this code.
• Distinguish carefully from type 1 or type 2 diabetes, which are not drug-induced.
• Do not use this code if the patient is in a nonketotic hyperglycemic-hyperosmolar coma; a more specific code exists for that severe presentation.
