Adverse effect of nonsteroidal anti-inflammatory drugs, subs

This code signifies a patient experiencing an unintended and undesirable reaction to an NSAID other than salicylates, pyrazolones, propionic acid derivatives, or other specified NSAIDs. This adverse effect is being addressed during a follow-up visit or during the recovery phase of the initial treatment.

Apply this code when a patient presents for ongoing management of an adverse reaction to a non-specific NSAID, such as gastrointestinal upset, renal dysfunction, or allergic reaction, after the initial treatment for the adverse effect has begun. This includes situations where the patient is still experiencing symptoms or is being monitored for resolution.

• Always sequence the code for the specific adverse effect (e.g., gastritis, acute kidney injury) first, followed by this code.
• Ensure the documentation clearly identifies the NSAID as "other" or unspecified, and that the encounter is for follow-up care.
• Distinguish from initial encounters (A) or sequela (S) by verifying the "D" seventh character for subsequent care.
