Patient presents with postpartum thrombocytopenia, diagnosed at [Number] days postpartum.  Initial platelet count is [Number] x 10^9L, obtained on [Date].  Patient's delivery was [Vaginal or Cesarean] on [Date] at [Gestational age] weeks.  Pregnancy was complicated by [List any relevant complications, e.g., preeclampsia, gestational diabetes, HELLP syndrome].  No history of pre-existing thrombocytopenia or other bleeding disorders.  Patient reports [Symptoms related to thrombocytopenia, e.g., easy bruising, petechiae, bleeding gums, epistaxis] or denies bleeding symptoms.  Physical examination reveals [Relevant findings, e.g., petechiae, purpura, ecchymosis] or no abnormal findings.  Peripheral blood smear reviewed and shows [Findings, e.g., decreased platelets, no evidence of schistocytes].  Other possible causes of thrombocytopenia, such as immune thrombocytopenic purpura (ITP), disseminated intravascular coagulation (DIC), and thrombotic thrombocytopenic purpura (TTP), have been considered and ruled out based on clinical presentation, laboratory findings, and negative [Specific tests used to rule out other diagnoses].  Diagnosis of postpartum thrombocytopenia established based on low platelet count in the postpartum period and exclusion of other etiologies.  Plan includes close monitoring of platelet counts, with repeat complete blood count (CBC) scheduled for [Date/Timeframe].  Patient education provided regarding signs and symptoms of bleeding and precautions to minimize bleeding risk.  Management will depend on the severity of thrombocytopenia and the presence of bleeding.  Consideration for platelet transfusion will be given if platelet count falls below [Number] x 10^9L or if bleeding develops.  Follow-up with hematology is scheduled for [Date/Timeframe].  ICD-10 code D69.6, other specified coagulation defects, is documented for billing purposes.
