Poisoning by propionic acid deriv, accidental, sequela

This code signifies a long-term health problem or residual effect resulting from an accidental overdose or poisoning by propionic acid derivatives, such as ibuprofen or naproxen. The initial acute poisoning event has resolved, but the patient continues to experience related complications or conditions.

Apply this code when documenting a chronic condition or permanent damage directly attributable to a past unintentional poisoning by propionic acid derivatives. Examples include persistent renal impairment, gastrointestinal ulcers, or other organ damage that developed as a consequence of the original toxic exposure. This code is used after the acute phase of the poisoning has passed.

• Always sequence this 'S' code after the code(s) describing the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to the past propionic acid derivative poisoning.
• Do not use for acute poisoning events; those require an initial encounter ('A') or subsequent encounter ('D') character.
