Bitten by nonvenomous snake, sequela

This code indicates the long-term effects or complications arising from a bite by a nonvenomous snake. It is used when the initial injury has healed, but the patient continues to experience residual symptoms or conditions directly attributable to the original bite. These sequelae might include chronic pain, scarring, nerve damage, or persistent infection.

Apply this code when documenting a patient encounter for a condition that is a direct consequence of a nonvenomous snake bite that occurred in the past. This would include follow-up visits for scar revision, management of chronic nerve pain, or treatment of a long-standing infection at the bite site. It is appropriate when the acute phase of the injury has passed.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., scar, chronic pain).
• Ensure documentation clearly links the current condition to the historical nonvenomous snake bite.
• Do not use for initial encounters or acute treatment of the bite; those require codes from the acute injury chapter.
