M11.9 is a billable ICD-10 code used to specify a medical diagnosis of crystal arthropathy, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like M11.9 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Crystal arthropathy
- Crystal arthropathy of ankle AND/OR foot
- Crystal arthropathy of elbow
- Crystal arthropathy of multiple sites
- Crystal arthropathy of pelvis
- 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).

If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Over time, a swollen joint can become severely damaged. Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin.
Types of arthritis include:
- Osteoarthritis is the most common type of arthritis. It's often related to aging or to an injury.
- Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this kind of arthritis.
- Juvenile arthritis is a type of arthritis that happens in children.
- Infectious arthritis is an infection that has spread from another part of the body to the joint.
- Psoriatic arthritis affects people with psoriasis.
- Gout is a painful type of arthritis that happens when too much uric acid builds up in the body. It often starts in the big toe.
