Following labor and delivery, what is the correct ICD-10-CM code for acute kidney failure?

The appropriate ICD-10-CM code for acute kidney failure following labor and delivery is O90.4. This code specifically pertains to a diagnosis of acute renal failure that can occur in the postpartum period. It is crucial to use the correct codes that accurately describe the condition and its timing relative to the patient's delivery.

In this context, O90.1 refers to a complication of the puerperium, which does not specifically denote kidney failure. O90.2 is related to acute pulmonary edema post-delivery, while O90.3 addresses complications related to anesthetic and other interventions. Therefore, O90.4 is the most accurate choice as it directly captures the acute kidney failure associated with the postpartum phase, ensuring proper coding and communication within healthcare documentation.
