Type 2 diabetes mellitus with hyperglycemia

This code signifies a diagnosis of type 2 diabetes mellitus accompanied by an elevated blood glucose level. It indicates that the patient's diabetes is currently poorly controlled, specifically manifesting as hyperglycemia.

Apply this code when documentation explicitly states type 2 diabetes and also notes the presence of hyperglycemia. This is appropriate for patients whose blood glucose readings are consistently above target ranges, requiring management for the elevated levels.

• Always sequence the diabetes code first, followed by any associated complications.
• Do not use this code if the hyperglycemia is due to a transient, non-diabetic cause (e.g., stress-induced hyperglycemia in a non-diabetic patient).
• Ensure documentation specifies "type 2 diabetes" and "hyperglycemia" for accurate code assignment.
