Long term (current) use of insulin

This code indicates a patient's ongoing, regular use of insulin therapy. It signifies that insulin is a current and established part of their treatment regimen for diabetes, regardless of the type of diabetes or the specific insulin product used.

Assign this code when a patient is actively receiving insulin as a long-term medication. This includes patients with Type 1 diabetes who are insulin-dependent, as well as Type 2 diabetics who require insulin to manage their blood glucose levels. It should be used in conjunction with the appropriate diabetes mellitus code.

• Always sequence this code secondary to the definitive diagnosis for which the insulin is prescribed (e.g., E10.x or E11.x).
• Do not use this code for temporary insulin use, such as during an acute illness or for gestational diabetes if insulin is discontinued post-partum.
• Distinguish carefully from long-term use of other antidiabetic medications, referencing the Excludes2 notes.
