Insect bite (nonvenomous) of right thumb, sequela

This code signifies a long-term or late-effect condition resulting from a nonvenomous insect bite on the patient's right thumb. This could include persistent scarring, chronic dermatitis, nerve damage, or other lasting complications directly attributable to the original bite. The "sequela" indicates that the acute phase of the bite has passed, and the current encounter addresses a residual problem.

Use this code when documenting an encounter for a patient presenting with a chronic or residual condition of the right thumb that is a direct consequence of a past nonvenomous insect bite. This applies when the initial injury has healed, but a lasting effect, such as a permanent scar or ongoing pain, is being treated or evaluated. It should be used for follow-up care related to these persistent issues.

• Always assign an additional code to specify the exact nature of the sequela (e.g., L90.5 for scar conditions, L30.9 for unspecified dermatitis).
• Ensure documentation clearly links the current right thumb condition to a previous nonvenomous insect bite.
• Do not use this code for the initial treatment of an acute insect bite; instead, use the appropriate acute injury code.
