A dermatology pathology report describes a neoplasm of uncertain behavior. The assessment does not use ‘unspecified behavior’ language. Which neoplasm-table concept applies?
Select an answer to reveal the explanation.
Short Explanation
‘Uncertain’ and ‘unspecified’ sound alike but they’re different Index doors. Uncertain behavior is a histology call—think ‘we’re not sure how this will act.’ Unspecified means the note never told you the behavior. Match the pathology words to the right table path.
Full Explanation
ICD-10-CM distinguishes neoplasms of uncertain behavior from neoplasms of unspecified behavior. Uncertain behavior reflects documented histology indicating uncertain biologic behavior, while unspecified behavior applies when behavior is not stated. Coders use the neoplasm table and Index pathways that match the documented language rather than defaulting to malignant or benign. Personal history codes are inappropriate for an active neoplasm under evaluation.
