Type 2 diab w hyprosm w/o nonket hyprgly-hypros coma (NKHHC)

This code signifies type 2 diabetes complicated by a hyperosmolar state, characterized by extremely high blood glucose levels and severe dehydration, but without the patient progressing to a nonketotic hyperglycemic-hyperosmolar coma (NKHHC). It indicates a significant metabolic derangement requiring medical intervention to correct fluid and electrolyte imbalances and reduce hyperglycemia.

Use this code for patients with type 2 diabetes experiencing hyperosmolarity, documented by elevated serum osmolality and severe hyperglycemia, but who are not in a comatose state. Documentation should clearly state "hyperosmolarity" or "hyperosmolar state" in the context of type 2 diabetes, explicitly ruling out NKHHC.

• Do not use this code if the patient is in a nonketotic hyperglycemic-hyperosmolar coma; a more specific code exists for that condition.
• Ensure documentation differentiates between hyperosmolarity and diabetic ketoacidosis (DKA), as these are distinct diabetic complications.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is an co-existing condition impacting care.
