P83.4 — Breast engorgement of newborn
P83.4 is a billable, specific ICD-10-CM code for breast engorgement of newborn. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Noninfective mastitis of newborn
Other codes that can never be billed with P83.4
These codes carry an Excludes1 note pointing at P83.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P83.4 alone.
Risk adjustment
P83.4 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 P83.4 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 P83.4.
