Corrosion of unspecified degree of left forearm, subs encntr

This code describes a chemical burn of the left forearm where the specific depth of the burn (e.g., first, second, or third degree) is not documented. It indicates that the patient is receiving follow-up care for this corrosion, beyond the initial treatment phase.

Use this code for subsequent encounters when a patient presents for ongoing treatment, wound care, or evaluation of a chemical burn to the left forearm, and the degree of the burn was not specified in the medical record. This applies to situations like dressing changes, re-evaluations, or monitoring healing progress.

• Ensure the documentation clearly states "left forearm" and that the encounter is for follow-up care.
• Only use this code when the degree of corrosion is truly unspecified; if a degree is documented, a more specific code should be chosen.
• The "D" seventh character signifies a subsequent encounter, meaning care after the initial active treatment.
