Complication of inhalation therapy, subsequent encounter

This code signifies a complication arising from medical inhalation therapy that is being addressed during a follow-up visit. It covers adverse events such as respiratory distress, infection, or other systemic reactions directly attributable to the inhaled substance or delivery method. The "D" indicates that this is a subsequent encounter for the ongoing management of this complication.

Apply this code when a patient presents for continued care of an adverse effect or injury directly resulting from a previous inhalation therapy. This includes follow-up appointments for monitoring the resolution of the complication, adjusting treatment, or managing persistent symptoms. It is appropriate after the initial treatment of the complication has already occurred.

• Ensure documentation clearly links the complication to the inhalation therapy and specifies it's a follow-up visit.
• Always sequence this code after the primary diagnosis for the specific complication (e.g., pneumonia, allergic reaction).
• Do not use for the initial encounter of the complication; use the "A" (initial encounter) seventh character instead.
