December
Coding Errors/Modifiers
| 1. | How do I bill for a procedure that is performed bilaterally? |
|
Some procedures, even though they can be performed bilaterally, are not shown on the on the MPFSDB as having indicator "1" in the bilateral column. This means that they cannot be billed with modifier 50. Medicare carriers are not able to override such restrictions found on the MPFSDB. For procedures performed bilaterally which do not allow modifier 50, bill the service on two separate lines, and append modifier LT (for left) on the first line of service, and modifier RT (for right) on the second line of service.

Address/Phone/Fax/Web Address
| 1. | I have a patient who is enrolled in the Medicare Advantage program through United Healthcare. Do you know how I can get their phone number? |
|
This Website has the most current listing of contact information, including phone numbers, for all Medicare Advantage plans. It is important to remember that Medicare Advantage plans work like a Health Maintenance Organization (HMO) program and replace traditional Medicare. Posted (09/04/07) |
|
| 2. | I have received notification that Medicare is monitoring my paper claims filing under the Administrative Simplification Compliance Act (ASCA). This states that I should be trying to file my claims electronically. Do you offer any type of guidance or software that can help me get started with electronic filing? We do not have a large volume of Medicare claims, but maybe we should file them electronically anyway. |

|
Posted (09/04/07) |
|
| 1. | Why are my therapy codes denying? I always bill therapy procedure codes and are paid for them; so, why are they denying now? |
|
In order to pay correctly, you must bill therapy procedure codes with a modifier. Wisconsin Physicians Service (WPS) Medicare outlines this instruction in medical policy PhysMed-001, page 34. By category, the appropriate therapy modifiers and their corresponding usage, are:

Duplicate Claim Denial | |
| 1. | I called the Interactive Voice Response (IVR) system to see if I could find out why I had not received payment on a claim I submitted. The IVR stated that the claim denied as a duplicate. What is going on? |
|
Posted (09/04/07) |
|
| We continually receive duplicate denials on radiology services performed multiple times per day to a patient. Why? | |
|
A provider may perform multiple procedures, or "repeat procedures" to a patient on a single day. These are more common with radiology and clinical laboratory services. If Wisconsin Physicians Service (WPS) Medicare cannot accept multiple numbers of services (quantity billing), then the provider of service must bill separate line items for each service. Providers can apply modifier 76 (radiology or diagnostic services) or modifier 91(clinical laboratory services only) to the second and subsequent lines of service to avoid duplicate denials. You may find additional information on this topic at the following Website: Posted (12/26/07) |
|
Payment Explanation/Calculation | |
| 1. | Why was my claim paid at a lower allowed amount for surgery than what is shown on the Medicare fee schedule? |
|
In addition, we frequently publish articles in our monthly newsletter, the Communiqué, which address this topic. Finally, the Medicare Physician Fee Schedule Database (MPFSDB) contains indicators which point to whether or not a given procedure code is subject to multiple surgery guidelines. When this applies, Medicare reduces reimbursement for second (and additional) procedures. You may find the MPFSDB on the CMS website. Posted (09/04/07) |

|
CMS-1500 Claim Form Item | |
| 1. | In what field on the CMS-1500 claim form do I place the provider's National Provider Identifier (NPI) number(s)? |
|
The reporting scenarios listed above are only a few of the many instances where billers need to report a provider's National Provider Identifier (NPI) on the CMS-1500 claim form. For a complete listing of all fields, and the information required, please refer to CMS's Internet Only Manual (IOM) 100-04, Chapter 26, Sections 10.2-10.4. Information specific to NPI is contained in Section 10.4. You can find these instructions on the CMS Website at http://www.cms.hhs.gov/manuals/downloads/clm104c26.pdf Posted (10/08/07) |
