Includes

Conditions this code covers.

  • infections acquired in utero or during birth

Other codes that can never be billed with P35

These codes carry an Excludes1 note pointing at P35. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P35 alone.

  • B25Cytomegaloviral disease
  • P23.0Congenital pneumonia due to viral agent
  • P59.2Neonatal jaundice from other and unspecified hepatocellular damage
  • A92.5Zika virus disease
  • B00Herpesviral [herpes simplex] infections
  • B06Rubella [German measles]

Risk adjustment

P35 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 P35

7 child codes. Green means billable.
