Florida Medicare Billing Support
Medicare Billing Built Around Today’s Rules
Medicare billing in Florida requires more than submitting the right CPT or HCPCS code. Practices must account for the correct Medicare Administrative Contractor, Local Coverage Determinations, Billing and Coding Articles, diagnosis-to-procedure relationships, documentation requirements, modifiers, utilization limits, and changing CMS guidance.
For Florida healthcare providers, First Coast Service Options is the Medicare Part A and Part B MAC for Jurisdiction N, while CGS Administrators handles DMEPOS claims through DME MAC Jurisdiction C.
A diagnosis code that appears to support a service does not automatically establish medical necessity. The documentation must support the service under the Medicare rules and coverage policy applicable to the date of service.
Quest National Services helps Florida practices manage medical billing, coding, claims, denials, appeals, payer follow-up, and broader revenue cycle workflows.
Know Your Medicare Jurisdiction
Who Is the Medicare Administrative Contractor for Florida?
Florida falls under different Medicare contractor jurisdictions depending on the type of Original Medicare claim being submitted.
Florida Medicare Part A & Part B
First Coast Service Options, Inc. is Florida’s current Medicare Part A and Part B MAC.
Florida belongs to A/B MAC Jurisdiction N (JN), which includes:
- Florida
- Puerto Rico
- U.S. Virgin Islands
Florida contractor numbers are 09101 for Part A and 09102 for Part B.
Florida DME Medicare Claims
Florida DMEPOS claims fall under DME MAC Jurisdiction C, administered by CGS Administrators, LLC.
The Jurisdiction C contractor number is 18003.
DME suppliers may need to review:
- Applicable DME LCD
- Policy Article
- Written order requirements
- Face-to-face requirements when applicable
- Continued-use and continued-need documentation
MAC Contract Updates
Are Florida’s Medicare MACs Changing?
As of September 1, 2026, CMS continues to identify First Coast Service Options as Florida’s Jurisdiction N A/B MAC and CGS Administrators as its Jurisdiction C DME MAC.
CMS lists an anticipated contract end date of April 2029 for the current First Coast Jurisdiction N contract and August 2027 for the CGS Jurisdiction C contract.
Those anticipated contract end dates are not the same as announced contractor transition dates. Florida providers should continue monitoring CMS and contractor communications for confirmed changes.
DME suppliers should also monitor developments involving the DMEPOS Competitive Bidding Program Round 2028.
LCDs & Medical Necessity
How Does Medicare Determine Medical Necessity in Florida?
Having a valid CPT or HCPCS code and an ICD-10-CM diagnosis listed in a Medicare article does not automatically establish medical necessity.
A Florida Medicare billing workflow should evaluate the complete coverage path:
- National Coverage Determination, when applicable
- Local Coverage Determination
- Billing and Coding Article
- CPT or HCPCS requirements
- Supporting ICD-10-CM diagnosis
- Clinical documentation
- Modifiers, frequency, units, and place of service
- Policy version applicable to the date of service
I have gone back to seeing my patients and no longer have to worry or follow up on the billing part of my practice because QNS has me covered.
Coverage Rules
LCDs, Billing Articles & the Date of Service
A Local Coverage Determination generally establishes the clinical circumstances under which a service may be considered reasonable and necessary. A related Billing and Coding Article may provide claim-level details such as CPT/HCPCS codes, supporting ICD-10-CM diagnoses, modifiers, units, and billing instructions.
Both should be reviewed together when applicable.
Medicare policies also change over time. When reviewing an older denial, recoupment, appeal, or aging claim, practices should use the Medicare policy version that applied to the actual date of service rather than automatically relying on the newest version available.
The absence of a Florida LCD does not automatically mean a service is payable. National coverage rules, CMS manuals, documentation standards, NCCI edits, supervision requirements, and individual medical review may still apply.
CPT & ICD-10 Examples
Florida Medicare Medical Necessity Examples
The following examples show how procedure codes, diagnosis codes, and documentation can interact under applicable First Coast and CGS Medicare policies.

Medical Necessity Reminder
An ICD-10-CM code appearing in a Medicare article does not guarantee coverage.
The patient’s clinical record must independently support the service under the complete Medicare coverage requirements.
Split/Shared E/M Compliance
How to Prepare for a Medicare Split/Shared E/M Audit
Split/shared E/M billing can create significant documentation risk for physician groups when qualifying facility services are performed by both a physician and a non-physician practitioner in the same group.
The practitioner who performs the substantive portion bills the qualifying service.
For eligible non-critical-care split/shared visits, the substantive portion can generally be established through:
- More than 50% of combined qualifying time
- A substantive part of the medical decision-making
The claim also requires Medicare’s designated FS modifier when split/shared billing requirements are met.
Denial Management
Find the Medicare Denial Cause Before Resubmitting
A Medicare denial is not always fixed by changing a code and immediately resubmitting the claim.
The underlying issue may involve:
- Diagnosis-to-procedure mismatch
- Insufficient medical-necessity documentation
- Modifier or frequency requirements
- Missing orders or signatures
- Provider eligibility or place of service
- DME continued-coverage requirements
- Incorrect Medicare policy version
- Coding or bundling rules
- Split/shared documentation
A stronger workflow identifies the actual reason, determines whether correction or appeal is appropriate, assembles the necessary support, and follows the claim through resolution.
Working with Adam on consulting for out of network benefits. I have been very impressed by professionalism and explaining of very complex & confusing issues in easy terms.

Customized Around Your Practice
How Much Does Medicare Billing Support Cost?
Billing complexity varies considerably by specialty, provider count, claim volume, payer mix, existing A/R, technology, and the services your practice needs.
Quest can customize the billing relationship around your practice rather than requiring every organization to use the same service package.
When comparing billing companies, consider more than the percentage alone. Ask what happens after a claim is denied, who follows unpaid claims, who manages appeals, what reporting is included, and how much billing work still falls back on your internal team.
Have questions? We’ve got answers.
Who is the Medicare Administrative Contractor for Florida?
First Coast Service Options, Inc. is the current Medicare Part A and Part B MAC for Florida. Florida belongs to A/B MAC Jurisdiction N (JN), which also includes Puerto Rico and the U.S. Virgin Islands.
Which DME MAC handles durable medical equipment claims for Florida?
Florida DMEPOS claims are handled through DME MAC Jurisdiction C, administered by CGS Administrators, LLC. The Jurisdiction C contractor number is 18003.
Are there any upcoming Medicare MAC changes affecting Florida?
As of September 1, 2026, CMS continues to list First Coast Service Options for Florida’s A/B Jurisdiction N and CGS Administrators for DME Jurisdiction C. CMS-listed anticipated contract end dates should not be interpreted as announced contractor transition dates.
How should Florida providers check Medicare medical necessity requirements?
Providers should review the applicable National Coverage Determination, Local Coverage Determination, Billing and Coding Article, CPT or HCPCS requirements, supporting ICD-10-CM diagnoses, documentation requirements, modifiers, frequency limits, and the policy version effective for the date of service.
Does an ICD-10 code listed by Medicare automatically prove medical necessity?
No. A diagnosis code may appear in a Medicare Billing and Coding Article and still fail medical review if the patient’s record does not support the clinical indications and documentation requirements of the applicable coverage policy.
Which Medicare policy should be used when reviewing an older claim?
Use the policy version that was effective on the claim’s date of service. When reviewing an older denial, appeal, recoupment, or aging claim, do not automatically apply the newest LCD or article currently displayed.
Who should bill a Medicare split/shared E/M visit?
The practitioner who performs the substantive portion bills the qualifying split/shared service. For eligible non-critical-care visits, this may generally be determined by more than 50% of the combined qualifying time or a substantive part of the medical decision-making. The qualifying claim also requires the FS modifier.
What should a Florida practice do before resubmitting a denied Medicare claim?
Identify the actual denial cause before resubmitting. The issue may involve diagnosis-to-procedure mismatch, insufficient medical-necessity documentation, modifiers, frequency limits, missing orders or signatures, provider eligibility, place of service, DME requirements, coding edits, or split/shared documentation.
