About coding sternum agenesis
The ICD-10-CM code for sternum agenesis is Q76.7 (Congenital malformation of sternum).
Within Q76 (congenital malformations of spine and bony thorax), Q76.7 is specifically for congenital malformation of sternum. Related codes cover spina bifida occulta (Q76.0), Klippel-Feil syndrome (Q76.1), congenital spondylolisthesis (Q76.2), congenital scoliosis due to congenital bony malformation (Q76.3), other congenital malformations of spine, not associated with scoliosis (Q76.4), cervical rib (Q76.5), other congenital malformations of ribs (Q76.6), other congenital malformations of bony thorax (Q76.8) 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.
