What MS-DRG does O26.73 group to?

When subluxation of symphysis (pubis) in the puerperium is the principal diagnosis on an inpatient stay, it groups to MS-DRG 769, 776, with relative weights from 0.6718 to 1.6666 depending on complications. Higher weights mean higher Medicare reimbursement.

Who can O26.73 be reported for?
