M70 MS-DRGs
As the principal diagnosis, the billable codes under M70 group to MS-DRG 555, 556, 557, or 558 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
- DRG 555 Signs and Symptoms of Musculoskeletal System and Connective Tissue with MCC (48 of 75 codes)
- DRG 556 Signs and Symptoms of Musculoskeletal System and Connective Tissue without MCC (48 of 75 codes)
- DRG 557 Tendonitis, Myositis and Bursitis with MCC (27 of 75 codes)
- DRG 558 Tendonitis, Myositis and Bursitis without MCC (27 of 75 codes)

Wounds and Injuries
An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.
