When bilious vomiting of newborn is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, with relative weights from 4.1073 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.

Is P92.01 a CC or MCC?

It does not count when the principal diagnosis is one of the 2 closely related codes in its exclusion list.

Not as a rule. The Excludes1 note on P92.01 lists "bilious vomiting in child over 28 days old (R11.14)".
