Underdosing of drugs affecting uric acid metabolism, subs

This code signifies that a patient is experiencing an adverse effect due to taking less than the prescribed or recommended dose of medication intended to manage uric acid levels. This underdosing is occurring during a follow-up visit for the initial underdosing event.

Use this code when a patient presents for ongoing management or evaluation of symptoms directly related to insufficient intake of drugs like allopurinol or febuxostat, and this is not the first encounter for this specific underdosing issue. It applies when the underdosing is causing a clinical problem, such as uncontrolled gout or hyperuricemia.

• Always sequence this code after the code(s) for the specific condition being treated by the underdosed medication (e.g., Gout).
• Ensure documentation clearly states "underdosing" and specifies the drug class (affecting uric acid metabolism).
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
