Food in pharynx causing asphyxiation, sequela

This code signifies a long-term or residual health problem resulting from a past episode of food lodged in the pharynx, which led to asphyxiation. The initial acute event has resolved, but the patient continues to experience related complications or lasting effects. This could include chronic respiratory issues, neurological damage from hypoxia, or persistent swallowing difficulties.

Use this code when documenting a patient presenting with a current condition directly attributable to a prior choking incident involving food in the pharynx that caused asphyxiation. This applies to follow-up encounters for ongoing management of sequelae, such as chronic aspiration pneumonia, vocal cord paralysis, or cognitive deficits stemming from the anoxic event. Do not use for the initial acute choking episode.

• Always assign an additional code(s) to specify the exact nature of the sequela (e.g., specific respiratory condition, neurological deficit).
• Ensure documentation clearly links the current condition to the past asphyxiation event caused by food in the pharynx.
• This "S" code indicates a sequela and should be used for conditions that are the late effects of the initial injury.
