A physician asks: "Can I bill for coumadin management for patients in the nursing home? I sometimes get 25 calls a month with PTINR results, and have to make decisions about the patient's coumadin dose. Can I bill for that?"
Unfortunately, no.
Medicare considers this part of the pre and post work of an E/M service, and does not reimburse it separately. There are CPT® codes for this service: 99363 and 99364, but they have a status indicator of bundled and so are not separately reimburseable. The CPT® Care Plan Oversight codes 99374--99380 are also not paid by Medicare. These do describe CPO of patients in a nursing facility, 15-29 minutes/month, or over 30 minutes.
Medicare's own HCPCS CPO codes do not inculde the care of nursing home patients, only HHA and hospice patients.
There is no separate reimbursement for managing a nursing home patient's coumadin dose based on updated INR data over the phone.
