Pregnancy related renal disease, unspecified trimester

This code signifies the presence of kidney disease that is either caused or exacerbated by pregnancy, when the specific trimester of gestation is not documented. It encompasses various renal conditions, such as pyelonephritis, glomerulonephritis, or other kidney disorders, that manifest during pregnancy.

Use this code when the medical record clearly indicates a diagnosis of renal disease directly related to the pregnant state, but the physician's documentation does not specify the trimester. This code is appropriate when the provider explicitly links the renal condition to the pregnancy without further detail on the gestational period.

• Ensure documentation explicitly states "pregnancy-related" or "due to pregnancy" for the renal disease.
• Avoid using this code if a more specific code for the type of renal disease (e.g., O26.831 for first trimester) or the specific renal condition (e.g., N10 for acute pyelonephritis) can be assigned.
• Always sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the pregnancy or delivery.
