O71.82Other specified trauma to perineum and vulva

O71.82 is the ICD-10-CM diagnosis code for other specified trauma to perineum and vulva. It belongs to category O71 (other obstetric trauma), block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within O71.8, choose O71.82 (Other specified trauma to perineum and vulva) only when documentation doesn't support a more specific option: laceration of uterus, not elsewhere classified (O71.81) and other specified obstetric trauma (O71.89).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 664.81 (other specified trauma to perineum and vulva, delivered, with or without mention of antepartum condition) and 664.84 (other specified trauma to perineum and vulva, postpartum condition or complication).
