About coding rib syndrome short
The ICD-10-CM code for rib syndrome short is Q77.2 (Short rib syndrome).
Within Q77 (osteochondrodysplasia with defects of growth of tubular bones and spine), Q77.2 is specifically for short rib syndrome. Related codes cover Achondrogenesis (Q77.0), Thanatophoric short stature (Q77.1), chondrodysplasia punctata (Q77.3), Achondroplasia (Q77.4), Diastrophic dysplasia (Q77.5), Chondroectodermal dysplasia (Q77.6), Spondyloepiphyseal dysplasia (Q77.7), other osteochondrodysplasia with defects of growth of tubular bones and spine (Q77.8) and 1 more.
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
