Toxic effect of rattlesnake venom, assault, subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from a rattlesnake venom exposure that occurred as a result of an intentional assault. The patient is no longer in the initial acute phase of treatment but is still receiving care related to the toxic effects.

Apply this code when documenting subsequent encounters for a patient who was deliberately exposed to rattlesnake venom by another individual. This includes visits for wound care, management of residual neurological or hematological effects, or ongoing rehabilitation after the initial hospitalization for the assault.

• Ensure the documentation clearly indicates the venom exposure was an assault and not accidental or self-inflicted.
• This "D" seventh character is for subsequent encounters; use "A" for initial treatment and "S" for sequelae.
• Always code the specific toxic effect(s) of the venom as additional diagnoses, if applicable.
