Is P78 a billable ICD-10-CM code?

No. P78 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does P78 sit in the tabular list?

Certain conditions originating in the perinatal period (P00-P96), in the block Digestive system disorders of newborn (P76-P78).

What cannot be coded together with P78?

P78 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

P78 — Other perinatal digestive system disorders

Non-billable headerICD-10-CM

P78 is a non-billable header ICD-10-CM code for other perinatal digestive system disorders. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

cystic fibrosis (E84.0-E84.9)
neonatal gastrointestinal hemorrhages (P54.0-P54.3)

Other codes that can never be billed with P78

These codes carry an Excludes1 note pointing at P78. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P78 alone.

P54.0Neonatal hematemesis
P54.1Neonatal melena
R19.7Diarrhea, unspecified
E83.11Hemochromatosis
K21Gastro-esophageal reflux disease
K27Peptic ulcer, site unspecified
K52.9Noninfective gastroenteritis and colitis, unspecified
K65Peritonitis

Risk adjustment

P78 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead P78

6 child codes. Green means billable.
