Searching for Z381 brought me to a document entitled 'Draft ICD-10-CM/PCS MS-DRGv32 Definitions Manual' on the Centers for Medicare & Medicaid Services site (cms.gov).

In this document, Z381 is stated as being a:

Z381 Single liveborn infant, born outside hospital

Is it possible that this what was checked-in?

Also noticed 308 & 309 scrubbed from PFight.
