Other postpartum acute kidney failure

This code signifies the sudden and severe loss of kidney function occurring in the postpartum period, not otherwise specified. This acute renal impairment can manifest as an inability to excrete waste products, regulate fluid balance, or maintain electrolyte levels, developing after childbirth.

Use this code when documentation clearly indicates acute kidney failure with an onset during the puerperium, and a more specific cause (e.g., pre-eclampsia, hemorrhage) is not identified or coded separately. Supporting documentation would include physician notes detailing acute renal insufficiency, elevated creatinine/BUN, decreased urine output, and a clear temporal relationship to the postpartum period.

• Ensure the documentation explicitly links the acute kidney failure to the postpartum period.
• Do not use this code if a more specific cause of postpartum acute kidney failure (e.g., due to severe pre-eclampsia, obstetric shock) is documented and has a dedicated code.
• Sequence this code as a secondary diagnosis if the primary reason for the encounter is related to the underlying cause or complication of the acute kidney failure.
