Billing How-To: Should A Provider Change Tax IDs?

Despite disadvantages, a new tax ID is a must when physicians leave your group.

Question: One of our optometrists wants to stop billing under the group’s tax ID and start billing under his own tax ID. I’m concerned that doing so will confuse the insurance companies and slow down his income, even though he has personally called some to notify them of the change and the effective date. Some payers are now asking for new W9 forms. Is there an easy way to do it?

Answer: Your optometrist can change his tax ID at any time, but you must submit a new W9 to your payers, in addition to a letter explaining that he will no longer be practicing under the group’s tax ID.

Downside: Yes, the optometrist’s income will be slowed. You also run the risk that the payer’s enrollment department does not handle the paperwork properly. Other billers have reported instances of the income being paid to the old tax ID or not being paid at all. Claims can also be lost even though the correct paperwork has been submitted multiple times.

If your optometrist is currently part of a group, and he is leaving the group, he needs his own tax ID. Many legal issues will arise from this. For example, if he is staying in the same office suite, he will have to pay market rent for the offices and staff that he is using. When patients move between the old practice and his new practice, questions will arise about which patients are considered new and which are considered established patients.

Much of this will have to be determined by the legal structure that is set up as he leaves the group. This can be a much more complex change than it appears on the…

Diagnosis Coding: Here’s How To Decode Your Physician’s Notes

If the doctor does not circle a diagnosis, it may be up to you to find one.

Don’t let an incomplete superbill damage your chances of submitting an accurate claim. If the doctor in your office fails to indicate the ICD-9 code for the condition that he treated, you should read through his documentation to find which diagnoses you should report.

Open the Notes When You Have to — and Even When You Don’t

Suppose your physician hands you a superbill with the procedures circled and the diagnosis left blank.

You could ask the physician which diagnosis to report, or you could examine the documentation yourself. If your office has a policy that includes “coding by abstraction” by certified/qualified coders, then submitting charges based on what is supported (documented) in the note is appropriate, says Barbara J. Cobuzzi, MBA, CPC, CPCH,CPC-P, CENTC, CHCC, with CRN Healthcare Solutions in Tinton Falls, N.J. The physician should be signing off on these charges as part of your internal policy.

Some practices choose to review the documentation and compare it against any diagnoses recorded on the superbill, even when they aren’t required to. This ensures that the documentation matches the code selection every time.

When in Doubt, Confirm With the Physician

If you are new at coding diagnoses from the physician’s notes, you should doublecheck your code selections with the practitioners before submitting your claims.

“Until a coder feels comfortable with the ICD-9 books and the codes used more often in their office, it’s a good idea to run the choices by a clinician,” says Suzan Berman, CPC, CEMC, CEDC, senior manager of coding and compliance with the Physician Services Division of UPMC in Pittsburgh. “You never want to give a patient a disease or symptom they don’t have  ” or one more…
