O70.2

O70.2Third degree perineal laceration during delivery

Non-billable headerICD-10-CM

O70.2 is a non-billable header ICD-10-CM code for third degree 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.

  • anal sphincter tear during delivery without third degree perineal laceration (O70.4)
  • perineal laceration involving anal or rectal mucosa (O70.3)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Perineal laceration, rupture or tear during delivery as in O70.1, also involving anal sphincter
  • Perineal laceration, rupture or tear during delivery as in O70.1, also involving rectovaginal septum
  • Perineal laceration, rupture or tear during delivery as in O70.1, also involving sphincter NOS

Other codes that can never be billed with O70.2

These codes carry an Excludes1 note pointing at O70.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O70.2 alone.

  • O70.1Second degree perineal laceration during delivery
  • O70.4Anal sphincter tear complicating delivery, not associated with third degree laceration

Risk adjustment

O70.2 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.
