I have several pathologist that report diagnoses in their Pathology Report but when it comes to coding they may only list one of the diagnoses. Example #1 Three shave biopsies presented from three different body areas. One biopsy is reported as Malignant Melanoma while the other two are reported as Compound Nevus. The only ICD-10 code reported is C43.6 for the melanoma. Example #2 Pathology Report for Peripheral Blood Smear diagnosed as Thrombocytopenia and Normocytic Anemia while Peripheral Blood, Flow Cytometry diagnosed as Precursor B Lymphoblastic Leukemia. The only diagnosis coded is C91.00 for the leukemia. Is there any official guideline that states all diagnoses listed in the Pathology Report should be coded?
