2022 ICD-10-CM Code M11.879
Other specified crystal arthropathies, unspecified ankle and foot
Code Classification
M11.879 is a billable diagnosis code used to specify a medical diagnosis of other specified crystal arthropathies, unspecified ankle and foot. The code M11.879 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 M11.879 might also be used to specify conditions or terms like chondrocalcinosis due to dicalcium phosphate crystals, chondrocalcinosis due to dicalcium phosphate crystals, of the ankle and foot, chondrocalcinosis due to pyrophosphate crystals, chondrocalcinosis due to pyrophosphate crystals, of the ankle and foot or chondrocalcinosis of joint of ankle and/or foot.
Unspecified diagnosis codes like M11.879 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.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Chondrocalcinosis due to dicalcium phosphate crystals
- Chondrocalcinosis due to dicalcium phosphate crystals, of the ankle and foot
- Chondrocalcinosis due to pyrophosphate crystals
- Chondrocalcinosis due to pyrophosphate crystals, of the ankle and foot
- Chondrocalcinosis of joint of ankle AND/OR foot
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code M11.879 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 553 | BONE DISEASES AND ARTHROPATHIES WITH MCC | 08 | 1.2683 |
| 554 | BONE DISEASES AND ARTHROPATHIES WITHOUT MCC | 08 | 0.7904 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert M11.879 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code M11.879 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
Arthritis
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.
