P84 — Other problems with newborn
P84 is a billable, specific ICD-10-CM code for other problems with newborn. 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.
- Acidemia of newborn
- Acidosis of newborn
- Anoxia of newborn NOS
- Asphyxia of newborn NOS
- Hypercapnia of newborn
- Hypoxemia of newborn
- Hypoxia of newborn NOS
- Mixed metabolic and respiratory acidosis of newborn
Other codes that can never be billed with P84
These codes carry an Excludes1 note pointing at P84. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P84 alone.
Risk adjustment
P84 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.
Medicare coverage
P84 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How P84 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 P84.
