Unspecified open wound of left forearm, initial encounter

This code signifies an open wound on the left forearm where the specific type of wound (e.g., laceration, puncture, avulsion) is not documented. "Open wound" implies a break in the skin, exposing underlying tissues. "Initial encounter" indicates the patient is receiving active treatment for this injury.

This code is appropriate when a patient presents with an open wound to the left forearm, and the medical record lacks sufficient detail to specify the wound type. It is used for the initial visit where the injury is first evaluated and treated. Subsequent encounters for follow-up care of the same injury would require a different seventh character.

• Only use this code when the documentation explicitly states "unspecified" or provides no further detail regarding the wound type.
• Always strive for greater specificity if available in the medical record (e.g., laceration, puncture wound).
• Ensure the seventh character "A" is correctly applied for the initial encounter of this injury.
