Unsp inj unsp musc/fasc/tend at shldr/up arm, left arm, init

This code signifies an injury to an unspecified muscle, fascia, or tendon in the left shoulder or upper arm region. The exact nature of the injury (e.g., strain, tear) and the specific tissue involved are not documented. This code is used for the initial encounter with the patient for this injury.

Use this code when documentation indicates an injury to the left shoulder or upper arm musculature, fascia, or tendons, but lacks specificity regarding the exact tissue or type of injury. This is appropriate when the provider has not yet determined the precise diagnosis or when the documentation is incomplete.

• Avoid using this code if more specific information about the injured muscle, fascia, or tendon is available.
• Ensure the documentation clearly states "left arm" or "left shoulder and upper arm" to justify the laterality.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
