Adverse effect of pyrazolone derivatives, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to pyrazolone derivatives. These are non-opioid analgesics and anti-inflammatory drugs, and the sequela indicates that the initial adverse effect has resolved but left a lasting health problem.

Use this code when documenting a patient presenting with a chronic or permanent condition directly attributable to a previous adverse effect of pyrazolone derivatives. This applies when the acute adverse event has passed, but the patient continues to experience related symptoms or complications.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, liver damage).
• Ensure documentation clearly links the current condition to a past adverse reaction to pyrazolone derivatives.
• Confirm the adverse effect is no longer acute but has resulted in a lasting consequence.
