Also known as
Giant cell arteritis
Inflammation of large arteries, typically the temporal artery.

When to use each related code
| Description |
|---|
| Temporal artery inflammation, often with headache |
| Headache from large blood vessel dilation |
| Headache from trigeminal nerve irritation |
Coding GCA without specifying laterality (right, left, bilateral) can lead to claim denials and inaccurate data reporting. Use G91.00-G91.09.
Temporal artery biopsy results are crucial for confirming GCA. Documentation must support the diagnosis for accurate coding and reimbursement.
Discrepancies between clinical findings, imaging, and biopsy results can lead to coding errors. CDI specialists should clarify inconsistencies.
Q: What are the most specific and sensitive diagnostic tests for Temporal Arteritis, considering both cost-effectiveness and potential complications?
A: While temporal artery biopsy remains the gold standard for diagnosing Temporal Arteritis, its invasiveness and potential complications warrant careful consideration. Color Doppler ultrasound of the temporal arteries, particularly assessing for the halo sign, offers a non-invasive, cost-effective initial approach with good sensitivity and specificity. Elevated inflammatory markers like ESR and CRP are supportive but not specific. In cases with strong clinical suspicion but negative ultrasound, temporal artery biopsy should still be pursued. Explore how incorporating ultrasound into your diagnostic workflow can improve patient care and resource utilization. Consider implementing a standardized approach to Temporal Arteritis diagnosis based on current guidelines.
Q: How can I differentiate Temporal Arteritis from other conditions presenting with similar symptoms, such as migraine, trigeminal neuralgia, or other vasculitides, to ensure accurate diagnosis and avoid misdiagnosis?
A: Differentiating Temporal Arteritis from conditions with overlapping symptoms requires a thorough clinical assessment encompassing a detailed history, physical examination, and targeted investigations. Jaw claudication, scalp tenderness, and visual disturbances are highly suggestive of Temporal Arteritis but can also occur in other conditions like giant cell arteritis. Distinguishing features of Temporal Arteritis include new-onset headache in patients over 50, associated polymyalgia rheumatica symptoms, and markedly elevated inflammatory markers. Neuroimaging, particularly MRI, can help rule out other diagnoses like trigeminal neuralgia or intracranial lesions. Consider implementing a diagnostic algorithm to systematically evaluate patients presenting with these symptoms. Learn more about the specific clinical features that can help distinguish Temporal Arteritis from mimickers.
Patient presents with complaints consistent with possible temporal arteritis, also known as giant cell arteritis. Symptoms include new-onset headache localized to the temporal area, jaw claudication, scalp tenderness, vision changes such as diplopia or amaurosis fugax, and fatigue. Physical examination may reveal a tender, thickened, or nodular temporal artery, decreased temporal artery pulse, or scalp tenderness. Patient reports experiencing polymyalgia rheumatica symptoms including morning stiffness and proximal muscle pain. Laboratory findings demonstrate elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). A temporal artery biopsy is scheduled to confirm the diagnosis. Given the high suspicion for temporal arteritis, and the risk of vision loss, high-dose corticosteroid therapy with prednisone is initiated immediately to prevent irreversible complications. Patient education provided regarding the importance of medication adherence, potential side effects of corticosteroids, and regular follow-up appointments for monitoring of disease activity and medication adjustments. Differential diagnoses include migraine, trigeminal neuralgia, and other vasculitides. ICD-10 code G31.5 (Giant cell arteritis) is assigned. Treatment plan includes close monitoring of ESR and CRP levels, ophthalmologic evaluation, and consideration for bone density testing and prophylaxis due to long-term corticosteroid use. Patient instructed to report any new or worsening symptoms immediately.
