Other assault by drowning and submersion, subs encntr

This code signifies an assault where the victim was intentionally subjected to drowning or submersion by another person, and the current encounter is for follow-up care or treatment of residual effects. It indicates that the initial injury has already been addressed, and the patient is now receiving ongoing management for related conditions.

Apply this code when a patient presents for a subsequent visit related to injuries sustained from an assault involving drowning or submersion. This includes appointments for physical therapy, psychological counseling, wound care, or monitoring of long-term complications following the initial acute treatment.

• Ensure documentation clearly states the encounter is for follow-up care of a previously treated assault.
• Always sequence this external cause code after the primary diagnosis code(s) describing the specific injuries or conditions being treated.
• Verify that the "D" seventh character for "subsequent encounter" is appropriate for the patient's current stage of care.
