About coding Tower skull
The ICD-10-CM code for Tower skull is Q75.058 (Other multi-suture craniosynostosis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q75.058.
Within Q75.05, choose Q75.058 (Other multi-suture craniosynostosis) only when documentation doesn't support a more specific option: Cloverleaf skull (Q75.051) and Pansynostosis (Q75.052).
Don't report Q75.058 together with the conditions in its Excludes1 note: coronal craniosynostosis, bilateral (Q75.022) and lambdoid craniosynostosis, bilateral (Q75.042).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
