Puncture wound w/o foreign body of oth part of head, sequela

This code signifies a past injury to a non-specified area of the head, excluding the eye, ear, nose, lip, or oral cavity, that resulted from a sharp object penetrating the skin without leaving any foreign material behind. The "sequela" designation indicates that this code is used to report a current condition or complication that is a direct result of that previous puncture wound.

Apply this code when documenting a long-term effect or residual condition stemming from a prior puncture wound to an unspecified part of the head. Documentation should clearly link the current complaint (e.g., scar, chronic pain, nerve damage) to the historical puncture injury and explicitly state the absence of a foreign body at the time of the original injury.

• Ensure the "S" seventh character for sequela is appropriately applied, indicating a late effect of the injury.
• Always code the specific sequela (e.g., scar, pain, nerve damage) first, followed by this external cause code.
• Verify documentation explicitly states "without foreign body" for the original puncture wound; otherwise, a different code may be appropriate.
