Underdosing of antirheumatics, NEC, subs

This code indicates that a patient is experiencing a health issue due to taking less than the prescribed amount of an antirheumatic medication, which is not classified elsewhere. This underdosing is occurring during a follow-up visit for the condition or complication resulting from the insufficient medication.

Use this code when a patient presents for ongoing treatment or monitoring of a condition exacerbated or caused by their consistent underdosing of an antirheumatic drug. This applies to situations where the patient is not taking enough medication, leading to a worsening of their rheumatic disease or related symptoms, and they are seen for a subsequent encounter.

• Always sequence this code after the code(s) for the specific condition being treated or complicated by the underdosing.
• Ensure documentation clearly states the patient is taking less than prescribed and that this is a subsequent encounter.
• Distinguish from initial encounters (A), subsequent encounters (D), and sequela (S) based on the encounter type.
