P39.1 — Neonatal conjunctivitis and dacryocystitis
P39.1 is a billable, specific ICD-10-CM code for neonatal conjunctivitis and dacryocystitis. 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.
- gonococcal conjunctivitis (A54.31)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Neonatal chlamydial conjunctivitis
- Ophthalmia neonatorum NOS
Other codes that can never be billed with P39.1
These codes carry an Excludes1 note pointing at P39.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P39.1 alone.
Risk adjustment
P39.1 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 P39.1 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 P39.1.
- Blennorrhea›inclusion(neonatal) (newborn)
- Conjunctivitis NOS›infantile
- Conjunctivitis NOS›neonatal
- Dacryocystitis›neonatal
- Inclusion›blennorrhea(neonatal) (newborn)
- Ophthalmia›neonatorum, newborn
- Conjunctivitis NOS›chlamydial›neonatal
