Anticoagulant Management

Effective January 1, 2007 there are two (2) new codes for anticoagulant management services:

99364       Each subsequent 90 days of therapy (must include a minimum of 3 INR measurements)

These codes may be reported for warfarin management in the outpatient, office or freestanding center site of service. Both the physician’s non-face-to-face services and face-to-face patient encounters are included in these codes, such as:

o        Reviewing, interpreting and ordering initial and repeat prothrombin time tests

o        Adjusting medication dosage

o        Altering and updating the care plan

o        Documenting results

o        Communicating results and instructions to the patient

New Inquiry and Response System (I&R) 

The American College of Surgeons Commission on Cancer (CoC) and the American Joint Committee on Cancer (AJCC) have made available to all cancer care professionals the Inquiry and Response System (I&R).  This is a repository of thousands of questions and answers related to registry data and cancer program standards, which many are used in the development, clarification, and revision of the Cancer Programs Standards or updated policies and procedures, expanded documentation, clearer communications, and increased education and training resources. The I&R team is comprised of CoC technical staff and physician experts in specialty fields.  You are encouraged to review the database and submit questions by going to http://web.facs.org/coc/default.htm.
