Duplicate Services
Exact duplicate claim/service
First Coast's claims systems use filters to screen out suspected duplicate claims. Such claims and claim lines are suspended.

First Coast staff then review suspended claims and determine to pay or deny. Your claim may be eligible for a clerical reopening.

When you submit a claim for multiple instances of a service, procedure or item, the claim should include an appropriate modifier to indicate that the service, procedure or item is not a duplicate.

Note that the modifier should be added to the second through subsequent line items for the repeat service, procedure or item.

If services provided are not related to the hospice patient’s terminal condition:
If claim was submitted without modifier GW, apply modifier and resubmit claim.

 Medicare does not cover services provided or ordered by a chiropractor that are not related to treatment by means of manual manipulation of the spine to correct a subluxation.
When billing HCPCS 98940, 98941 and 98942 for services related to active/corrective treatment for acute or chronic subluxation, a modifier is required.
Use First Coast's modifier validation tool to confirm relationship between modifiers and procedure codes.

If the claim is submitted without the applicable modifier, services are considered maintenance therapy, and the claim will deny.

In addition to these tips for handling most frequently denied claims, First Coast’s provider website offers many useful tools to manage Medicare billing and prevent denied claims. The most frequently-used tools are the Interactive LCD index and fee schedule look up. However, First Coast offers several more online tools to help you save time and get paid more quickly.

SPOT – Secure Provider Online Tool

With SPOT, Medicare providers have several tools available to diagnose, correct, and prevent denied claims. SPOT gives you the ability to view claims status and patient eligibility information online, access remittances, conduct detailed data analysis at the claim and provider levels, reopen claims to make clerical corrections on multiple lines, and submit redeterminations and additional development responses (ADRs). First Coast offers SPOT to providers at no charge.
“The SPOT simplifies the claims reopening process. It makes it 10 times better to go online and find information on my claims and fix it right there. It’s real time. I’m not wasting time on the phone,” said one provider who uses several of First Coast’s web tools to manage Medicare claims.

‘Incident-to’ self-service tool

The purpose of the incident-to self-service tool is to assist providers with understanding the CMS Part B incident-to requirements and to apply the rules to their individual given patient/provider circumstances and to understand documentation requirements.
"Incident-to" services are defined as those services that are provided incident to physician professional services in the physician's office or in a patient's home. Examples may include services supervised by a physician and provided by non-physician practitioners such as physician assistants, nurse practitioners, clinical nurse specialists, nurse midwives, or clinical psychologists.

Modifier details tool

Using the modifier details tool before you file a claim can help you prevent a claim denial for an invalid combination of procedure codes and modifiers. While the existence of a valid procedure/modifier combination does not necessarily imply Medicare coverage, the tool provides a level of assurance that the coding of a claim may be valid.

Request your personalized PDS report

The top denial codes represent all Part B Medicare providers in Florida, USVI and Puerto Rico. If you would like to see the top denial codes for your medical practice, order a provider data summary (PDS) report through your SPOT account.
The PDS is a free comprehensive billing report that helps identify potential Medicare billing issues through a detailed analysis of billing patterns in comparison with those of similar provider types. This report will assist in enhancing the accuracy and efficiency of your Medicare billing process.
“Getting to the reports is very easy,” says one provider who used the reports to improve the timing of processing claims in their practice from 13 days to three. “It [PDS report] provides a snapshot of the quality of the claims we are filing,” he said.
Here’s a sample of part of the PDS report that highlights top denial codes:
