Partial Thromboplastin Time (PTT) (Addition of ICD-9-CM V58.83, Encounter for therapeutic drug monitoring, as a covered indication)

CMS CAL document | source_status=Closed | review_type=New | public_comment_open=False | document_id=CAG-00338N

CMS has determined that ICD-9-CM diagnosis code V58.83, Encounter for therapeutic drug monitoring, flows from the existing narrative for conditions for which a PTT test is reasonable and necessary. We shall modify the list of “ICD-9-CM Codes Covered by Medicare Program” in the NCD for Partial Thromboplastin Time (PTT) by adding V58.83.
