Insect bite (nonvenomous) of r bk wl of thorax, sequela

This code describes the long-term effects or complications arising from a nonvenomous insect bite that occurred on the right posterior aspect of the chest wall. These sequelae could include chronic scarring, persistent discoloration, nerve damage, or other lasting issues directly attributable to the original bite. It indicates that the acute phase of the bite has passed, and the patient is now experiencing residual problems.

Use this code when documenting a patient presenting for treatment of a chronic condition or lasting consequence directly resulting from a nonvenomous insect bite on the right back wall of the thorax. This applies when the original bite is no longer active, but its effects persist and require ongoing management. Examples include treating a keloid scar formed at the bite site or managing chronic pruritus.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the specified anatomical site.
• Do not use this code for acute insect bites; those require codes from the S20.461A-D series.
