Toxic effect of venom of centipede/millipede, acc, sequela

This code signifies the long-term or residual effects resulting from an accidental envenomation by a centipede or venomous millipede. It is used when the acute toxic effects have resolved, but the patient continues to experience related health problems.

Apply this code when documenting conditions such as chronic pain, nerve damage, scarring, or persistent allergic reactions that are directly attributable to a centipede or venomous millipede bite that occurred in the past. This code is appropriate for follow-up encounters addressing these lasting complications.

• Always assign a code for the specific sequela (e.g., chronic pain, neuropathy) in addition to this code.
• Ensure documentation clearly links the current condition to the past centipede or millipede envenomation.
• Verify the "S" seventh character is appropriate, indicating a sequela, not an acute event.
