Patient presents with complaints consistent with lumbar disc degeneration.  Symptoms include chronic low back pain, potentially radiating to the buttocks and thighs, described as aching, stiffness, or burning.  The patient may also experience lumbar radiculopathy, sciatica, or neurogenic claudication, exacerbated by activities such as bending, lifting, or prolonged sitting.  Physical examination reveals limited lumbar range of motion, tenderness to palpation in the lumbar spine, and possibly positive straight leg raise test indicating nerve root impingement.  Diagnostic imaging, such as MRI of the lumbar spine, may demonstrate decreased disc height, disc bulging or herniation, osteophyte formation, and facet joint arthrosis, confirming the diagnosis of degenerative disc disease.  Differential diagnoses considered include lumbar spinal stenosis, facet joint syndrome, and sacroiliac joint dysfunction.  The initial treatment plan includes conservative management with NSAIDs for pain relief, physical therapy focusing on core strengthening and flexibility exercises, and patient education on proper body mechanics.  Further interventions may include epidural steroid injections or surgical consultation if symptoms persist or worsen despite conservative treatment.  Follow-up is scheduled to assess treatment efficacy and adjust the plan as needed.  ICD-10 code M51.36 (other intervertebral disc degeneration, lumbar region) is appropriate for this encounter.
