About coding Spondyloepiphyseal dysplasia
The ICD-10-CM code for Spondyloepiphyseal dysplasia is Q77.7 (Spondyloepiphyseal dysplasia).
Within Q77 (osteochondrodysplasia with defects of growth of tubular bones and spine), Q77.7 is specifically for Spondyloepiphyseal dysplasia. Related codes cover Achondrogenesis (Q77.0), Thanatophoric short stature (Q77.1), short rib syndrome (Q77.2), chondrodysplasia punctata (Q77.3), Achondroplasia (Q77.4), Diastrophic dysplasia (Q77.5), Chondroectodermal dysplasia (Q77.6), other osteochondrodysplasia with defects of growth of tubular bones and spine (Q77.8) and 1 more.
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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), 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.
