Matrixectomy

“I have a rheumatoid patient with a grossly deformed interphalangeal joint with significant osseous malformations leading to a chronic ingrown toenail on the hallux fibular border. I have ruled out any infection, osteomyelitis, or neoplasm. The bone is grossly hypertrophic and needs excision along with the nail structures on the fibular border. There also may need to be some plastic closure performed. What are the appropriate ICD10 and CPT codes reflective of this scenario?”
