About coding Floppy syndrome baby
The ICD-10-CM code for Floppy syndrome baby is P94.2 (Congenital hypotonia).
Within P94 (disorders of muscle tone of newborn), P94.2 is specifically for congenital hypotonia. Related codes cover transient neonatal myasthenia gravis (P94.0), congenital hypertonia (P94.1), other disorders of muscle tone of newborn (P94.8) and disorder of muscle tone of newborn, unspecified (P94.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 794 (Neonate with Other Significant Problems, relative weight 1.4935), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
