P08.0 — Exceptionally large newborn baby
P08.0 is a billable, specific ICD-10-CM code for exceptionally large newborn baby. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Usually implies a birth weight of 4500 g. or more
Other codes that can never be billed with P08.0
These codes carry an Excludes1 note pointing at P08.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P08.0 alone.
- P08.1Other heavy for gestational age newborn
Risk adjustment
P08.0 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.
How P08.0 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to P08.0.
- Heavy-for-dates NEC›exceptionally(4500g or more)
- Large-for-dates NEC›exceptionally(4500g or more)
- Birth›weight›4500 grams or more
- Excess, excessive, excessively›large›infant
