Diseases of the nervous system complicating the puerperium

This code signifies a neurological disorder that arises or worsens during the puerperium, the period immediately following childbirth. It encompasses a range of conditions affecting the brain, spinal cord, or peripheral nerves that are directly related to the postpartum state. Examples include postpartum eclampsia, stroke, or exacerbation of pre-existing neurological conditions.

Apply this code when documentation clearly links a nervous system disease to the postpartum period. This includes conditions diagnosed for the first time during the puerperium or pre-existing neurological conditions that significantly worsen due to the physiological changes of childbirth and recovery. The medical record should specify the neurological condition and its onset or exacerbation within the puerperal timeframe.

• Always code the specific neurological condition first, followed by this code to indicate the complication of the puerperium.
• Ensure documentation explicitly states the connection between the neurological issue and the postpartum period; avoid assuming causality.
• Distinguish from neurological conditions present before pregnancy that are not exacerbated by the puerperium, or those occurring during pregnancy (O99.31-).
