Corrosion of unspecified degree of left wrist, subs encntr

This code signifies a chemical burn of the left wrist where the specific depth or degree of the injury is not documented. It indicates that the patient is receiving follow-up care for this corrosion, beyond the initial treatment phase.

Apply this code for subsequent encounters when a patient presents for ongoing management, such as wound care, re-evaluation, or monitoring of a chemical burn to the left wrist. This is appropriate when the initial encounter for the burn has already been coded and the degree of the burn was not specified.

• Ensure the documentation clearly states "left wrist" and "corrosion" (chemical burn).
• Confirm this is a subsequent encounter; for initial treatment, a different 7th character would be used.
• Only use this code when the degree of the burn is explicitly unspecified in the medical record.
