Bit/stung by nonvenom insect & oth nonvenom arthropods, sqla

This code indicates a long-term or late-developing complication resulting from a bite or sting from a nonvenomous insect or other nonvenomous arthropod. These sequelae are conditions that persist or arise after the initial acute injury has resolved. Examples include chronic skin changes, scarring, or persistent nerve irritation.

Use this code when documenting conditions that are direct, lasting consequences of a nonvenomous insect or arthropod bite or sting, and are being treated long after the initial incident. This applies when the patient presents for management of these residual effects, not for the acute injury itself.

• 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 bite or sting.
• Do not use for acute reactions or immediate complications; those require codes from the initial encounter or subsequent encounter categories.
