Insect bite of unspecified part of neck, sequela

This code signifies a lasting health problem or complication resulting from an insect bite on an unspecified area of the neck. It indicates that the acute phase of the bite has passed, and the patient is now experiencing a residual effect, such as scarring, chronic dermatitis, or nerve damage.

Apply this code when documentation clearly indicates a sequela (late effect) directly attributable to a past insect bite on the neck. This typically involves conditions that manifest after the initial healing of the bite, requiring ongoing management. Documentation should specify the "sequela" nature of the condition and its link to a prior insect bite.

• Ensure the documentation explicitly states "sequela" or "late effect" of an insect bite.
• Do not use for acute insect bites; those require codes from the initial encounter series.
• Always sequence the code for the specific sequela (e.g., L90.5 for scar conditions) first, followed by this code as a secondary diagnosis.
