O86.00

O86.00 — Infection of obstetric surgical wound, unspecified

Billable / specific codeICD-10-CM

O86.00 is a billable, specific ICD-10-CM code for infection of obstetric surgical wound, unspecified. It is valid for submission on a claim.

Excludes1 inherited from the categories above O86.00

These are not written on O86.00, but they bind it: a note on a category applies to every code beneath it. Billing O86.00 with anything listed here is a denial.

Written on O86.0 — Infection of obstetric surgical wound

complications of procedures, not elsewhere classified (T81.4-)
postprocedural fever NOS (R50.82)
postprocedural retroperitoneal abscess (K68.11)

Excludes2 inherited from the categories above O86.00

Also inherited, and the opposite of Excludes1: these conditions are not part of O86.00, but a patient can have both, so you may code both.

Written on O86 — Other puerperal infections

infection during labor (O75.3)
obstetrical tetanus (A34)

Other codes that can never be billed with O86.00

These codes carry an Excludes1 note pointing at O86.00. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O86.00 alone.

N71Inflammatory disease of uterus, except cervix

Risk adjustment

O86.00 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.

Medicare coverage

O86.00 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
