About Q75.08

Q75.08 is the ICD-10-CM diagnosis code for other single-suture craniosynostosis. It belongs to category Q75 (other congenital malformations of skull and face bones), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q75.0, choose Q75.08 (Other single-suture craniosynostosis) only when documentation doesn't support a more specific option: unspecified (Q75.00), Sagittal craniosynostosis (Q75.01), Coronal craniosynostosis (Q75.02), Metopic craniosynostosis (Q75.03), Lambdoid craniosynostosis (Q75.04) and multi-suture craniosynostosis (Q75.05).

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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2024, effective October 1, 2023.
