About coding bilateral craniosynostosis
The ICD-10-CM code for bilateral craniosynostosis is Q75.002 (Craniosynostosis, unspecified type, bilateral).
Within Q75.00 (craniosynostosis, unspecified), Q75.002 is specifically for craniosynostosis, unspecified type, bilateral. Related codes cover type, unilateral (Q75.001) and unspecified (Q75.009).
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.
