About coding Brachycephaly
The ICD-10-CM code for Brachycephaly is Q75.022 (Coronal craniosynostosis, bilateral).
Within Q75.02 (Coronal craniosynostosis), Q75.022 is specifically for Coronal craniosynostosis, bilateral. Related codes cover unilateral (Q75.021) and unspecified (Q75.029).
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.
