Contusion of unspecified shoulder, initial encounter

This code signifies a bruise or contusion to the shoulder region where the specific side (left or right) is not documented. It indicates damage to the soft tissues, such as muscle, fat, and blood vessels, resulting from blunt force trauma without an open wound.

This code is appropriate for initial encounters when a patient presents with a shoulder contusion and the medical record does not specify whether it's the left or right shoulder. It should be used when the injury is new or the patient is receiving initial active treatment for the contusion.

• Only use this code when the laterality of the shoulder is truly unspecified in the documentation.
• Always strive for greater specificity (e.g., S40.011A for right shoulder) if available in the medical record.
• Ensure the "A" seventh character is used only for the initial encounter for active treatment of the injury.
