Which code indicates the dehiscence of a cesarean section wound requiring readmission?

• A. O85
• B. O90.0
• C. Q18.0
• D. Z38.00

Answer: (B)

The correct code indicating the dehiscence of a cesarean section wound requiring readmission is O90.0. This code specifically addresses complications following a cesarean delivery, particularly post-operative issues such as wound dehiscence.

The classification of O90.0 pertains to complications and abnormalities following the surgery, focusing on conditions that necessitate further medical attention or intervention. This makes it appropriate for situations where a cesarean section wound has reopened or hasn't healed properly, resulting in the need for readmission.

The other choices relate to different conditions or classifications that do not specifically denote the complication of wound dehiscence in this context. For example, O85 refers to puerperal sepsis, Q18.0 pertains to congenital malformations, and Z38.00 denotes a liveborn infant, which altogether do not fall under the complications associated with a cesarean wound. Understanding the specific meanings and applications of these codes within medical coding ensures accurate documentation and billing for healthcare services.
