Sacroiliac Joint Disease

Patient presents with complaints consistent with sacroiliac joint dysfunction, including lower back pain, buttock pain, and groin pain.  Symptoms may radiate to the posterior thigh and are often aggravated by prolonged standing, sitting, or activities involving weight-bearing and asymmetrical loading of the pelvis such as climbing stairs.  Pain is typically described as dull and achy, occasionally with sharp, stabbing exacerbations.  Physical examination reveals tenderness to palpation over the sacroiliac joint, positive findings on provocative maneuvers such as the FABER test, Gaenslen's test, and compression distraction tests.  Fortin finger test localizes pain to the posterior superior iliac spine.  Range of motion in the lumbar spine may be limited, though neurological examination is typically unremarkable, ruling out radiculopathy.  Differential diagnoses considered include lumbar disc herniation, piriformis syndrome, and osteoarthritis of the hip.  Imaging studies, including X-rays, MRI, or CT scan, may be obtained to assess for sacroiliitis, degenerative changes, or other underlying pathology.  Diagnosis of sacroiliac joint disease is based on clinical presentation, physical examination findings, and imaging results.  Treatment plan may include conservative measures such as physical therapy focusing on core strengthening and stabilization exercises, nonsteroidal anti-inflammatory drugs for pain management, and sacroiliac joint injections.  Patient education on proper body mechanics and activity modification is also essential.  Surgical intervention is rarely indicated and reserved for severe cases refractory to conservative treatment.  Follow-up appointment scheduled to monitor symptom improvement and adjust treatment plan as needed.  ICD-10 code M46.1, Sacroiliitis, not elsewhere classified, is considered for this encounter.  CPT codes for evaluation and management, physical therapy, injections, and imaging studies will be determined based on the specific services rendered.
