Specific codes depend on the type and location of the injury.

Causes of Left Shoulder Injuries

Left shoulder injuries can result from various factors, including:

✅ Trauma (falls, accidents, sports injuries)

✅ Repetitive strain (overuse in athletes or manual labor)

✅ Degenerative conditions (arthritis, tendon wear-and-tear)

✅ Frozen shoulder (adhesive capsulitis)

Real-Life Example: A Case of Misdiagnosis

John, a 45-year-old construction worker, suffered chronic left shoulder pain. His doctor initially coded it as a sprain (S43.402A), but an MRI later revealed a rotator cuff tear (S46.012A). Proper coding ensured John received the right physical therapy and avoided unnecessary surgery.
