Asphyx due to being trapped in bed linens, undet, subs

This code describes a case of asphyxiation resulting from a patient becoming entangled or trapped in bed linens, where the intent or circumstances surrounding the event are unclear or unknown. It specifically indicates that this is not the initial encounter for this injury, but rather a follow-up visit for ongoing care related to the asphyxiation.

Use this code for subsequent encounters when a patient is receiving continued treatment or monitoring for complications arising from asphyxiation due to being trapped in bed linens, and the cause of the trapping remains undetermined. This applies to follow-up visits after the initial diagnosis and treatment have been rendered.

• Ensure documentation clearly states the asphyxiation was due to bed linens and that the circumstances are undetermined.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for the initial diagnosis; a code with an "A" seventh character would be appropriate for the first encounter.
