Unspecified pre-eclampsia, unspecified trimester

This code represents a diagnosis of pre-eclampsia where the specific severity (e.g., with or without severe features) is not documented, and the trimester of pregnancy at the time of diagnosis is also not specified. Pre-eclampsia is a pregnancy-specific syndrome characterized by new-onset hypertension and proteinuria after 20 weeks of gestation, or new-onset hypertension with end-organ dysfunction.

Use this code when the medical record clearly indicates a diagnosis of pre-eclampsia but lacks details regarding the presence of severe features or the specific trimester of pregnancy. This code is appropriate when the provider's documentation states "pre-eclampsia, unspecified" or similar, without further elaboration on severity or timing.

• Avoid using this code if the documentation specifies "pre-eclampsia with severe features" or "without severe features"; instead, select a more specific O14.0- or O14.1- code.
• If the trimester is documented, even if severity is not, choose a more specific code from the O14.9 series that includes the trimester (e.g., O14.92 for second trimester).
• Always query the provider for more specific details regarding severity and trimester to allow for more precise coding and better data capture.
