About coding Fontanel rupture
The ICD-10-CM code for Fontanel rupture is P13.1 (Other birth injuries to skull).
Within P13, choose P13.1 (Other birth injuries to skull) only when documentation doesn't support a more specific option: fracture of skull due to birth injury (P13.0), birth injury to femur (P13.2), birth injury to other long bones (P13.3), fracture of clavicle due to birth injury (P13.4), birth injuries to other parts of skeleton (P13.8) and unspecified (P13.9).
Don't report P13.1 together with the conditions in its Excludes1 note: cephalhematoma (P12.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for P13.1)
- cephalhematoma (P12.0)
