Puncture wound without foreign body, unsp foot, init encntr

This code signifies a penetrating injury to the foot caused by a sharp object, where no foreign material remains embedded in the tissue. It indicates that the specific location on the foot (e.g., left, right, or specific digit) was not documented or is unknown. This is the initial encounter for this injury.

This code is appropriate for patients presenting with a fresh puncture wound to the foot, such as from stepping on a nail or thorn, where the foreign body has either been removed prior to presentation or was never retained. It should be used when the medical record does not specify which foot was injured or if the injury affects both feet and laterality is not documented.

• Always strive for greater specificity regarding laterality (left vs. right foot) if documented.
• If a foreign body is present, a different code from the S91.32- series would be appropriate.
• Ensure the "A" seventh character for initial encounter is used for the first time the patient is seen for this injury.
