Strain unsp musc/fasc/tend at shldr/up arm, unsp arm, init

This code signifies a non-specific injury to the soft tissues (muscle, fascia, or tendon) of the shoulder and upper arm region. It indicates a stretching or tearing of these tissues without specifying the exact muscle or tendon involved, or the laterality of the injury.

This code is appropriate for initial encounters where a patient presents with symptoms consistent with a strain in the shoulder or upper arm, but diagnostic imaging or a detailed physical examination has not yet identified the specific muscle, fascia, or tendon affected. It is a placeholder when the exact anatomical site or laterality of the strain is unknown or not documented.

• Only use this code when the specific muscle, fascia, or tendon involved in the shoulder/upper arm strain is truly unspecified in the medical record.
• Avoid using this code if documentation specifies laterality (e.g., "right shoulder strain") or a particular muscle (e.g., "biceps strain").
• Always strive for a more specific code if additional clinical information becomes available during subsequent encounters.
