About coding baby large
The ICD-10-CM code for baby large is P08.1 (Other heavy for gestational age newborn).
Within P08, choose P08.1 (Other heavy for gestational age newborn) only when documentation doesn't support a more specific option: Exceptionally large newborn baby (P08.0) and late newborn, not heavy for gestational age (P08.2).
Don't report P08.1 together with the conditions in its Excludes1 note: newborn with a birth weight of 4500 or more (P08.0), syndrome of infant of diabetic mother (P70.1) and syndrome of infant of mother with gestational diabetes (P70.0).
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 P08.1)
