What modifier should a physician of record for nursing home admission append?

The appropriate modifier for a physician of record for nursing home admission is indeed the A1 modifier. This modifier is specifically used to indicate that a nursing facility admission is being performed by a physician who is established as the patient's attending physician.

In the context of coding for nursing home admissions, using the A1 modifier helps clearly identify that the physician has made the admission decision and is responsible for the patient's care during their stay. This level of specificity is important for coding purposes, as it helps ensure accurate billing and documentation in alignment with Medicare and other insurance guidelines.

Modifiers play a crucial role in the coding process by providing additional context about the services rendered, which can impact reimbursement. Using the correct modifier, such as A1 in this case, enhances the clarity of the claim and supports proper billing practices for nursing home admissions.
