Gastr contents in resp tract, part unsp cause asphyx, sqla

This code signifies a past event where gastric contents entered the respiratory tract, leading to asphyxiation, with the patient now experiencing a long-term complication or residual effect. It indicates that the initial aspiration event and its acute consequences have resolved, but ongoing issues related to that event persist.

This code is appropriate for patients presenting with chronic respiratory problems, neurological deficits, or other sequelae directly attributable to a prior aspiration of gastric contents that caused asphyxiation. It should be used when the patient is no longer in the acute phase of the aspiration event but is being treated for its lasting impact.

• Always ensure documentation clearly links the current condition to a past aspiration event causing asphyxiation.
• Do not use this code for acute aspiration events; those require codes from the T17.91- series without the 'S' seventh character.
• Assign additional codes for the specific sequelae (e.g., chronic lung disease, anoxic brain injury) to fully describe the patient's condition.
