Eclampsia, unspecified as to time period

This code represents a severe, life-threatening complication of pregnancy characterized by new-onset grand mal seizures in a woman with pre-eclampsia. It indicates the occurrence of eclampsia without further specification regarding whether it occurred during pregnancy, labor, or the puerperium.

Use this code when the medical record clearly documents a diagnosis of eclampsia, but the specific timing (antepartum, intrapartum, or postpartum) is not specified by the provider. Documentation must explicitly state "eclampsia" or "eclamptic seizure" without further temporal detail.

• Do not use this code if the documentation specifies the timing of the eclampsia (e.g., antepartum, intrapartum, postpartum); instead, use the more specific O15.0-O15.2 codes.
• Always sequence this code as a primary diagnosis when eclampsia is the reason for the encounter.
• Ensure documentation differentiates eclampsia from other seizure disorders in pregnancy (e.g., epilepsy, cerebral hemorrhage).
