The code M12.80 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code M12.80 might also be used to specify conditions or terms like arthritis due to parasitic infection, arthropathy associated with a mycosis, arthropathy associated with bacterial disease, arthropathy associated with dermatological disorder, arthropathy associated with viral disease , parasitic postinfectious arthropathy, etc.
Unspecified diagnosis codes like M12.80 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including
- Arthritis - inflammation of a joint. It causes pain, stiffness, and swelling. Over time, the joint can become severely damaged.
- Bursitis - inflammation of a fluid-filled sac that cushions the joint
- Dislocations - injuries that force the ends of the bones out of position
Treatment of joint problems depends on the cause. If you have a sports injury, treatment often begins with the RICE (Rest, Ice, Compression, and Elevation) method to relieve pain, reduce swelling, and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation, and sometimes surgery. For arthritis, injuries, or other diseases, you may need joint replacement surgery to remove the damaged joint and put in a new one.
