Unspecified pre-eclampsia, third trimester

This code signifies a diagnosis of pre-eclampsia occurring during the third trimester of pregnancy, where the specific severity (e.g., mild, severe) is not documented. Pre-eclampsia is a pregnancy complication characterized by new-onset hypertension and proteinuria after 20 weeks gestation.

This code is appropriate when a pregnant patient in her third trimester is diagnosed with pre-eclampsia, but the medical record does not specify whether it is mild or severe. Documentation should clearly indicate pre-eclampsia and the gestational period.

• Only use this code when the severity of pre-eclampsia is truly unspecified in the medical record.
• Always strive for greater specificity if documentation allows (e.g., O14.03 for mild, O14.13 for severe).
• Remember to also code for any associated complications or manifestations of the pre-eclampsia.
