Ask ACDIS: Use of tumor board notes post discharge

Q: Some physicians are uncomfortable making addendums to the discharge summary to include the pathological findings (e.g., malignancy). Instead, they dictate a tumor board note to summarize the course of treatment and final pathological diagnosis. However, the tumor board note is usually dated a few days after the patient is discharged. When a condition meets guidelines for the inpatient admission, is it appropriate to use documentation dated outside the inpatient admission for coding purposes?
