Underdosing of insulin and oral hypoglycemic drugs, subs

This code indicates that a patient is experiencing adverse effects or complications due to taking less insulin or oral antidiabetic medication than prescribed, and this is not the initial encounter for this specific underdosing event. It signifies a situation where the patient's diabetes management is compromised due to insufficient medication intake, leading to potential hyperglycemia or other related issues.

Use this code when a patient presents for follow-up care, monitoring, or treatment of conditions directly resulting from their underdosing of insulin or oral hypoglycemic drugs. This applies to situations such as uncontrolled blood glucose levels, diabetic ketoacidosis, or hyperosmolar hyperglycemic state, when the underdosing is the identified cause and the patient is returning for further management.

• Always assign an additional code for the specific manifestation of the underdosing (e.g., E10.65 for Type 1 diabetes with hyperglycemia).
• Ensure documentation clearly states that the underdosing is the cause of the current condition and that this is not the first time the patient is being seen for this particular underdosing episode.
• Distinguish carefully between underdosing (patient took less than prescribed) and noncompliance (patient did not take medication as prescribed, which could lead to underdosing but is a broader concept).
