Valid for Submission
M12.9 is a billable diagnosis code used to specify a medical diagnosis of arthropathy, unspecified. The code M12.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code M12.9 might also be used to specify conditions or terms like acute arthropathy, ankle joint inflamed, arthropathy, arthropathy associated with cystic fibrosis, arthropathy associated with syringomyelia , arthropathy of elbow, etc.
Unspecified diagnosis codes like M12.9 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.

- CRYSTAL ARTHROPATHIES-. joint disorders that are characterized by accumulation of microcrystals in and around the joint including in the synovial fluid. they are classified according to the chemical nature of the crystals such as calcium pyrophosphate; basic calcium phosphates; and monosodium urate see uric acid.
- ARTHROPATHY NEUROGENIC-. chronic progressive degeneration of the stress bearing portion of a joint with bizarre hypertrophic changes at the periphery. it is probably a complication of a variety of neurologic disorders particularly tabes dorsalis involving loss of sensation which leads to relaxation of supporting structures and chronic instability of the joint. dorland 27th ed

Convert M12.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code M12.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
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.
