NCD Decision Memo for Prothrombin Time (PT):Addition of two ICD-9-CM diagnosis codes

CMS has determined that two ICD-9-CM diagnosis codes: 786.50, Chest pain, unspecified and 786.51, Precordial pain, flow from the existing narrative for conditions for which a prothrombin time (PT) test is reasonable and necessary. Consequently, CMS will add these two ICD-9-CM diagnosis codes to the list of “ICD-9-CM Codes Covered by the Medicare Program” for the national coverage determination (NCD) for PT testing, as stated in Section 190.17 of the NCD Manual.
