Underdosing of nonsteroidal anti-inflammatory drugs, subs

This code signifies a patient's underdosing of a non-specific NSAID, meaning they took less than the prescribed or recommended amount, and this is being addressed during a follow-up visit. This underdosing could lead to uncontrolled pain, inflammation, or other conditions the NSAID was intended to treat. The "subsequent encounter" indicates that the initial treatment for the underdosing or its effects has already begun.

Apply this code when a patient presents for ongoing management of a condition exacerbated by, or resulting from, insufficient intake of an NSAID other than aspirin, salicylates, or propionic acid derivatives. This would include scenarios where a physician is monitoring the patient's response to adjusted medication dosages or addressing persistent symptoms due to previous underdosing.

• Ensure documentation clearly specifies "underdosing" and identifies the medication as a non-specific NSAID.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the condition being treated by the NSAID as the primary diagnosis, with this underdosing code as a secondary diagnosis.
