Protozoal diseases complicating the puerperium

This code signifies a maternal infection caused by a protozoan organism that arises during the puerperium, the period following childbirth. These infections can affect various organ systems and are directly related to the recent pregnancy and delivery. Examples include malaria, toxoplasmosis, or amebiasis occurring postpartum.

Apply this code when a patient in the postpartum period (up to one year after delivery) is diagnosed with a protozoal infection. Documentation must clearly link the infection to the puerperal state, indicating it developed or was exacerbated during this time. Supporting documentation includes physician notes detailing the protozoal diagnosis and its onset relative to delivery.

• Always sequence this code after the specific protozoal infection code (e.g., B50-B64 for malaria, toxoplasmosis, etc.).
• Ensure the documentation explicitly states the infection occurred during the puerperium; avoid using for infections pre-existing or unrelated to pregnancy.
• Do not confuse with protozoal infections complicating pregnancy (O98.61-) or the childbirth (O98.62-).
