Patient presents with complaints of low back pain, a common symptom of lumbar spondylolisthesis.  The pain may radiate to the buttocks and legs, consistent with radiculopathy or neurogenic claudication.  Onset of pain may be insidious or related to a specific incident.  Physical examination reveals tenderness to palpation in the lumbar spine.  Neurological examination may demonstrate sensory deficits, muscle weakness, or altered reflexes in the lower extremities, depending on the degree of nerve root compression.  Range of motion in the lumbar spine may be limited due to pain and muscle spasm.  Radiographic imaging, such as lumbar X-rays, CT scan, or MRI, is indicated for diagnosis confirmation and grading of the spondylolisthesis.  Differential diagnoses include lumbar disc herniation, spinal stenosis, and degenerative disc disease.  Assessment suggests lumbar spondylolisthesis, likely at the L4-L5 or L5-S1 level.  Treatment plan includes conservative management with physical therapy focusing on core strengthening and pain management strategies such as NSAIDs, heat or ice therapy.  Patient education on proper body mechanics and activity modification is crucial.  Surgical intervention may be considered if conservative treatment fails to provide adequate relief or if neurological deficits progress.  Follow-up appointment scheduled to monitor symptoms and response to treatment.  ICD-10 code M43.1 will be used for documentation and billing purposes, specifying the level of spondylolisthesis as appropriate.  CPT codes for procedures, such as injections or physical therapy, will be documented accordingly.
