Open bite of unspecified ear, initial encounter

This code describes a traumatic open wound to an unspecified ear, characterized by a break in the skin from a bite. This injury exposes underlying tissues and is considered an initial encounter for treatment. It indicates the patient is receiving active treatment for the acute injury.

Use this code for a patient presenting with a fresh, open bite wound to either the right or left ear, where the specific ear is not documented. This code is appropriate when the patient is first seen for this injury and is undergoing initial evaluation and management, such as wound cleaning, debridement, or suturing. Documentation should clearly state "open bite" and "ear," with no laterality specified.

• Ensure documentation specifies "open bite" versus other types of open wounds (e.g., laceration, puncture) to the ear.
• If the specific ear (right or left) is documented, use the more specific code (S01.351A or S01.352A).
• Always append the appropriate seventh character for the encounter type (A for initial, D for subsequent, S for sequela).
