Fall into natrl body of water strk bottom cause drown, subs

This code describes an injury sustained from falling into a natural body of water, where the patient strikes the bottom, leading to drowning and submersion. The "D" indicates this is a subsequent encounter for care related to the initial injury. This could involve follow-up for respiratory complications, neurological sequelae, or other related issues.

Use this code for follow-up encounters when a patient presents for ongoing management of health problems directly resulting from an initial incident of falling into a natural body of water, striking the bottom, and experiencing drowning/submersion. This includes care for conditions like aspiration pneumonia, hypoxic brain injury, or other complications identified after the initial treatment phase.

• Ensure the "D" for subsequent encounter is appropriate; use "A" for initial encounters and "S" for sequela.
• Always code the specific type of natural body of water if known (e.g., river, lake) using an additional external cause code.
• Pair this code with other relevant diagnosis codes for specific injuries or conditions resulting from the drowning and submersion event.
