Patient presents with complaints consistent with spinal osteoarthritis, also known as spondylosis.  Symptoms include localized pain in the neck (cervical osteoarthritis) or lower back (lumbar osteoarthritis), stiffness, and reduced range of motion.  The patient reports pain exacerbation with activity and relief with rest.  On physical examination, tenderness to palpation along the affected spinal segments, crepitus, and limited spinal mobility were noted.  Radiographic imaging (X-ray, MRI) reveals characteristic degenerative changes, including osteophyte formation (bone spurs), joint space narrowing, and subchondral sclerosis.  The patient's symptoms and imaging findings correlate with a diagnosis of osteoarthritis of the spine.  Differential diagnoses considered included degenerative disc disease, spinal stenosis, and facet joint syndrome.  The initial treatment plan includes conservative management with nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief, physical therapy to improve strength and flexibility, and patient education on activity modification.  Follow-up is scheduled to monitor symptom progression and assess treatment efficacy.  Further interventions such as corticosteroid injections or surgical consultation may be considered if conservative measures fail to provide adequate symptom relief.  ICD-10 code M47.XX (for osteoarthritis of spine) is applied, with the appropriate sub-code specifying the affected region (cervical, thoracic, or lumbar).  Medical billing codes for the evaluation and management, imaging studies, and therapeutic interventions will be documented and submitted accordingly.
