O90: Complications of the puerperium, not elsewhere classified

O90.1: Disruption of perineal obstetric wound

The perineum is the region between the anus and vagina. During a birth, this region is sometimes injured.

Your wound was closed by a suture or staples, for example. There can be various reasons why the wound later reopened. For example, the stitched area may have been moved too much. An inflammation of the wound is also possible.
