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

This code signifies a nonvenomous insect bite located on the patient's right upper arm. It indicates that the patient is presenting for follow-up care, such as wound check, dressing change, or monitoring of healing, after the initial treatment of the bite.

This code is appropriate for subsequent visits related to a nonvenomous insect bite on the right upper arm. Examples include a patient returning to have a rash evaluated that developed days after the initial bite, or for a follow-up appointment to assess for signs of infection or delayed healing.

• Ensure the documentation clearly specifies the right upper arm as the location of the bite.
• Confirm the encounter is for follow-up care, not the initial presentation, to justify the "D" seventh character.
• Always code the specific type of insect bite if known and documented (e.g., mosquito, ant), otherwise use the unspecified nonvenomous bite code.
