Insect bite (nonvenomous) of left upper arm, subs encntr

This code signifies a nonvenomous insect bite located on the patient's left upper arm. It indicates that the patient is presenting for follow-up care or treatment of complications related to the initial bite, rather than the initial injury itself.

Use this code for patients returning for evaluation of a persistent rash, infection, or other sequelae from a nonvenomous insect bite on their left upper arm. It is appropriate for visits where the acute phase of the bite has passed, and the focus is on ongoing management.

• Ensure the documentation clearly specifies the left upper arm as the location of the bite.
• Confirm the encounter is for subsequent care, not the initial presentation, as indicated by the "D" seventh character.
• Verify the bite is explicitly documented as nonvenomous; otherwise, a different code may be required.
