Underdosing of propionic acid derivatives, subs encntr

This code indicates that a patient is experiencing an adverse effect or complication due to receiving an insufficient amount of a propionic acid derivative medication, such as ibuprofen or naproxen, during a follow-up visit. This underdosing is impacting the patient's current medical condition or treatment plan.

Use this code when a patient presents for ongoing management of a condition, and the physician documents that the patient's symptoms are not adequately controlled because they are taking less than the prescribed dose of a propionic acid derivative. This could be due to patient non-compliance, medication unavailability, or an error in dosage instructions that is being addressed in the current encounter.

• Always sequence this code after the code(s) for the specific condition being treated by the propionic acid derivative.
• Ensure documentation clearly states "underdosing" and specifies the medication class (propionic acid derivative).
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
