Valid for Submission
| ICD-10: | M31.6 |
| Short Description: | Other giant cell arteritis |
| Long Description: | Other giant cell arteritis |
Code Classification
M31.6 is a billable diagnosis code used to specify a medical diagnosis of other giant cell arteritis. The code M31.6 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 M31.6 might also be used to specify conditions or terms like anterior ischemic optic neuropathy, arteritic anterior ischemic optic neuropathy, arteritic anterior ischemic optic neuropathy due to giant cell arteritis, arteritic ischemic optic neuropathy, cerebral arteritis , cerebral arteritis in giant cell arteritis, etc.

Clinical Information
- GIANT CELL ARTERITIS-. a systemic autoimmune disorder that typically affects medium and large arteries usually leading to occlusive granulomatous vasculitis with transmural infiltrate containing multinucleated giant cells. the temporal artery is commonly involved. this disorder appears primarily in people over the age of 50. symptoms include fever; fatigue; headache; visual impairment; pain in the jaw and tongue; and aggravation of pain by cold temperatures. from adams et al. principles of neurology 6th ed
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code M31.6 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 |
|---|---|---|---|
| 545 | CONNECTIVE TISSUE DISORDERS WITH MCC | 08 | 2.4995 |
| 546 | CONNECTIVE TISSUE DISORDERS WITH CC | 08 | 1.2066 |
| 547 | CONNECTIVE TISSUE DISORDERS WITHOUT CC/MCC | 08 | 0.833 |
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 M31.6 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code M31.6 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
Giant Cell Arteritis
Giant cell arteritis is a disorder that causes inflammation of your arteries, usually in the scalp, neck, and arms. It narrows the arteries, which keeps blood from flowing well. Giant cell arteritis often occurs with another disorder called polymyalgia rheumatica. Both are more common in women than in men. They almost always affect people over the age of 50.
Early symptoms of giant cell arteritis resemble the flu: fatigue, loss of appetite, and fever. Other symptoms include
- Headaches
- Pain and tenderness over the temples
- Double vision or visual loss, dizziness
- Problems with coordination and balance
- Pain in your jaw and tongue
Your doctor will make the diagnosis based on your medical history, symptoms, and a physical exam. There is no specific test for giant cell arteritis, but you may have tests that measure inflammation.
Treatment is usually with corticosteroids. Early treatment is important; otherwise there is a risk of permanent vision loss or stroke. However, when properly treated, giant cell arteritis rarely comes back.
