Underdosing of antirheumatics, NEC, init

This code indicates that a patient is experiencing adverse effects or complications because they are taking less than the prescribed or recommended dose of an antirheumatic medication. This underdosing is not due to a physician's decision to reduce the dose, but rather an error or non-compliance on the patient's part.

Apply this code when a patient presents with worsening symptoms of a rheumatic condition due to insufficient intake of their prescribed antirheumatic drug. This is appropriate for the initial encounter where the underdosing is first identified and addressed.

• Always sequence this code after the code(s) for the specific adverse effect or complication being treated.
• Confirm that the underdosing is patient-driven and not a physician-directed dose reduction.
• Ensure the encounter is the initial presentation for this specific underdosing event.
