About coding Large-for-dates NEC
The ICD-10-CM code for Large-for-dates NEC is P08.1 (Other heavy for gestational age newborn). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P08.1.
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.
