About coding Postradiation therapy scoliosis
The ICD-10-CM code for Postradiation therapy scoliosis is M96.5 (Postradiation scoliosis).
Within M96 (intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified), M96.5 is specifically for Postradiation scoliosis. Related codes cover Pseudarthrosis after fusion or arthrodesis (M96.0), postlaminectomy syndrome, not elsewhere classified (M96.1), Postradiation kyphosis (M96.2), postlaminectomy kyphosis (M96.3), postsurgical lordosis (M96.4), fracture of bone following insertion of orthopedic implant, joint prosthesis, or bone plate (M96.6), other intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified (M96.8) and fracture of ribs, sternum and thorax associated with compression of the chest and cardiopulmonary resuscitation (M96.A).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 456 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with MCC, relative weight 7.6244), DRG 457 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with CC, relative weight 5.3668), DRG 458 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection without CC/MCC, relative weight 4.0388), DRG 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
