O70Perineal laceration during delivery

Non-billable headerICD-10-CM

O70 is a non-billable header ICD-10-CM code for perineal laceration during delivery. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • obstetric high vaginal laceration alone (O71.4)

Includes

Conditions this code covers.

  • episiotomy extended by laceration

Other codes that can never be billed with O70

These codes carry an Excludes1 note pointing at O70. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O70 alone.

  • N89.8Other specified noninflammatory disorders of vagina
  • N90Other noninflammatory disorders of vulva and perineum
  • O71.4Obstetric high vaginal laceration alone
  • O70.1Second degree perineal laceration during delivery
  • O70.2Third degree perineal laceration during delivery
  • O70.4Anal sphincter tear complicating delivery, not associated with third degree laceration
  • S31.4Open wound of vagina and vulva

Risk adjustment

O70 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 O70

6 child codes. Green means billable.
