Most podiatrists feel confident about the clinical side of opening a practice. Billing is where new practices tend to lose money in the first year. Florida adds its own complications: a large Medicare population, a no-fault auto insurance system, and a Medicaid program delivered through managed care plans. Understanding these pieces before you open saves months of delayed payments.
Get Enrolled and Credentialed Before You See Patients
Claims will not pay until you hold an NPI, a Florida license, and an active enrollment with each payer. Medicare enrollment runs through PECOS, and the Medicare Administrative Contractor for Florida is First Coast Service Options. Commercial payers such as Florida Blue, Aetna, Cigna, UnitedHealthcare, and Humana each have their own credentialing process, and most pull data from your CAQH profile.
Plan for 60 to 120 days per payer. Many payers do not backdate effective dates, so any patient you treat before approval may mean an unpaid claim or an out-of-network visit. Start applications three to four months before your opening date, and keep your CAQH profile attested and current. An expired attestation can stall an application without any warning.
Understand Florida’s Payer Mix
Florida has one of the highest shares of Medicare beneficiaries in the country, and a large portion of them are in Medicare Advantage plans instead of Original Medicare. Each Advantage plan can set its own referral rules, prior authorization requirements, and network participation. A patient who says they have Medicare may actually be covered by a private plan with different rules.
Medicaid in Florida is delivered mainly through Statewide Medicaid Managed Care plans. That means you register with the state through AHCA and also contract with the individual plans. Each plan has its own claim submission rules and timelines.
Because of this mix, verify eligibility and plan type at every visit, not just the first one. Coverage changes often, especially during open enrollment.
Know What Medicare Covers and What It Does Not
Medicare generally excludes routine foot care, such as nail trimming, callus paring, and corn removal. The exception is when a systemic condition, such as diabetes with neuropathy or peripheral vascular disease, puts the patient at risk. In those cases, coverage depends on documenting specific class findings and reporting the correct Q modifiers (Q7, Q8, or Q9) on the claim.
Medicare also requires that the physician managing the systemic condition has seen the patient within a set window before the foot care. Your notes need to show the clinical finding, the underlying condition, and the reason a podiatrist needs to perform the service. A claim with a correct code and thin documentation is a common audit target.
Mycotic nail treatbillment and therapeutic shoes for diabetic patients have their own documentation rules. Therapeutic shoes, for example, require a certifying statement from the physician managing the patient’s diabetes. Learn these rules before you see your first Medicare patient, since they apply to a large share of a typical podiatry caseload in Florida.
Coding Areas That Cause Denials in Podiatry
A few coding issues account for a large share of podiatry denials:
- Modifier 25. When you perform an evaluation and management service on the same day as a procedure, the E/M needs modifier 25 and notes that show it was separate and significant. Without both, the payer will often bundle it.
- Modifier 59 and X modifiers. These show that two procedures were distinct, but payers scrutinize them closely. Use them only when the documentation supports it.
- Toe and laterality modifiers. Procedures on individual toes need the correct toe modifiers, and diagnosis codes need laterality. Missing details lead to rejections that are easy to avoid.
- Global periods. Many podiatric surgeries carry 10-day or 90-day global periods, which include routine follow-up care. Billing a post-operative visit that falls inside the global period without the right modifier will be denied or recouped.
- Diagnosis specificity. Vague diagnosis codes fail medical necessity edits. Document the condition fully so the coder can select the most specific code.
Handle PIP and Workers’ Compensation Claims Correctly
Florida is a no-fault state, and personal injury protection covers a set amount of treatment for auto accident injuries. The patient generally must receive initial treatment within 14 days of the accident for PIP to apply. If you treat ankle and foot injuries from car accidents, confirm the claim number, the adjuster, and remaining benefits before treatment, and track the benefit limit as claims are paid.
Workers’ compensation follows a separate process with authorization requirements and a state fee schedule. Get authorization from the adjuster before providing care, and send documentation promptly. Both PIP and workers’ compensation claims fall apart when intake information is incomplete, so collect the details at scheduling.
Decide How You Will Run Billing
You have two realistic options: build an in-house billing function or hire outside help. In-house gives you direct control but means paying a salary, buying software, and training someone on podiatry-specific rules that change often. Outsourcing shifts that workload, usually in exchange for a percentage of collections. Some practices work with podiatry billing services that already understand the routine foot care exclusion, modifier use, and Florida payer rules, which can shorten the learning curve for a new practice.
Whichever route you take, measure results with a few numbers: clean claim rate, denial rate, and days in accounts receivable. A clean claim rate above 95 percent and days in A/R in the 30s are reasonable targets. If your numbers fall well outside those ranges, find out why before it becomes a cash flow problem.
Build Simple Habits That Protect Revenue
Good billing comes from consistent routines more than from any single tool:
- Verify eligibility before every visit and collect copays at the time of service.
- Enter charges within one or two days of the visit, while the details are fresh.
- Work denials within a week. Most can be corrected and resubmitted, but only if someone acts on them.
- Track timely filing limits. Medicare allows 12 months from the date of service, while many commercial payers allow far less, often 90 to 180 days.
- Review monthly reports on collections, denials, and aging balances so problems show up early.
