Insect bite (nonvenomous) of flank, sequela

This code signifies a current health problem resulting from a past, nonvenomous insect bite on the patient's flank. The sequela indicates that the initial bite has resolved, but there are ongoing symptoms or conditions directly attributable to that prior injury. This could include chronic itching, scarring, or persistent skin changes.

Apply this code when documenting a patient presenting with a long-term complication or residual effect from a nonvenomous insect bite that occurred on the flank. This is appropriate for follow-up visits addressing the chronic issue, not the acute bite itself. Ensure the medical record clearly links the current condition to the previous insect bite.

• Always assign an additional code for the specific nature of the sequela (e.g., pruritus, dermatitis, scar).
• Do not use this code for acute insect bites; those require codes from the T14-T19 range.
• Verify that the documentation specifies the flank as the anatomical location of the original bite.
