Renal failure following incomplete spontaneous abortion

This code signifies the development of renal failure as a direct complication after an incomplete spontaneous abortion. An incomplete spontaneous abortion is one where some, but not all, products of conception have been expelled from the uterus. The renal failure can range from acute kidney injury to more severe forms.

Use this code when documentation clearly indicates a patient experienced renal failure following an incomplete spontaneous abortion. This diagnosis is supported by physician notes detailing the spontaneous abortion, subsequent renal dysfunction (e.g., elevated creatinine, decreased urine output), and a causal link between the two events.

• Always sequence the obstetric complication (O03.32) as the principal diagnosis if it is the reason for the encounter.
• Code the specific type of renal failure (e.g., N17.9 for acute kidney failure, unspecified) as an additional diagnosis.
• Ensure documentation specifies "incomplete" spontaneous abortion; other types of abortion complications have different codes.
