Ankylosing spondylitis of multiple sites in spine
ICD-10 M45.0 is a billable code used to indicate a diagnosis of ankylosing spondylitis of multiple sites in spine.
Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the axial skeleton, leading to pain and stiffness in the spine and sacroiliac joints. The condition is characterized by inflammation of the entheses, the sites where tendons and ligaments attach to bone, which can result in new bone formation and fusion of the vertebrae over time. Patients often present with chronic back pain and stiffness, particularly in the morning or after periods of inactivity. The disease can also affect multiple sites in the spine, leading to significant functional impairment. AS is associated with the HLA-B27 antigen, and its diagnosis is often supported by imaging studies showing sacroiliitis or syndesmophytes. Treatment typically involves nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, and in some cases, biologic agents. Early diagnosis and management are crucial to prevent long-term complications such as spinal deformity and reduced mobility.
Detailed history of symptoms, physical examination findings, imaging results, and treatment response.
Patients presenting with chronic back pain, stiffness, and positive HLA-B27 tests.
Documentation should include the impact of the disease on daily activities and any comorbid conditions.
Imaging studies, surgical notes if applicable, and functional assessments.
Patients with severe spinal deformities or requiring surgical intervention.
Accurate coding of surgical procedures related to spinal fusion or correction of deformities.
Used when treating associated joint pain in patients with ankylosing spondylitis.
Document the joint involved, the procedure performed, and the patient's response.
Rheumatologists may frequently perform this procedure for symptomatic relief.
The primary symptom is chronic back pain and stiffness, particularly in the lower back and hips, which improves with activity and worsens with rest.
