What happens when vascular lab testing is performed on the same day as a peripheral vascular intervention?

Our bundling logic evaluates whether the diagnostic study was used to determine the need for the intervention (in which case it may be separately billable with modifier -59/-XU) or was performed as part of the procedural workup (in which case it is bundled), applying the correct modifier based on documentation to avoid both denials and compliance risk.

How does the platform support prior authorization for endovenous ablation procedures (CPT 36475-36479)?

Our authorization manager tracks the required conservative therapy trial period (typically a minimum of weeks of compression therapy), documents reflux duration findings from duplex ultrasound exceeding payer thresholds (commonly 0.5 seconds for superficial veins), and compiles symptom documentation before submitting the authorization request.

How are peripheral vascular intervention codes (atherectomy, angioplasty, stenting) sequenced when multiple are performed in the same vessel?

Our coding engine applies CMS hierarchy rules that designate atherectomy as the primary billable intervention when performed alongside angioplasty or stenting in the same vessel, with angioplasty and stenting in the same territory considered inclusive, while interventions in separate vascular territories are billed with appropriate modifiers.

Does the system support billing for anticoagulation management services?

Yes. We support anticoagulation management billing including chronic care management (CPT 99490-99491) for patients on long-term anticoagulation, INR point-of-care testing (CPT 85610), and home INR monitoring (CPT 93792-93793), tracking the required monitoring frequency and documentation for each service.

How does the platform handle billing for critical limb ischemia (CLI) interventions?

CLI interventions are coded with attention to the documented Rutherford classification and tissue loss status, ensuring the medical necessity documentation supports the more aggressive intervention codes and that any related debridement or wound care services performed during the same encounter are coded and bundled correctly.

What support exists for billing carotid artery duplex screening and intervention?

Carotid duplex studies (CPT 93880-93882) are coded based on documented findings and frequency, with screening exams for asymptomatic patients distinguished from diagnostic exams for symptomatic patients, and any subsequent carotid stenting (CPT 37215-37217) is billed with correct embolic protection device documentation.

How does the system manage billing for compression therapy and venous insufficiency follow-up visits?

Follow-up visits during the conservative therapy trial period for venous insufficiency are coded as standard E/M visits with documentation of compression therapy compliance and symptom progression, building the documentation timeline that supports subsequent ablation procedure authorization if conservative measures fail.

Why Vascular Medicine billing is different

Vascular medicine practices generate revenue through a combination of non-invasive vascular laboratory testing, office-based peripheral vascular interventions, anticoagulation management, and venous insufficiency procedures, each governed by distinct coding and prior authorization requirements. Bundling rules between diagnostic vascular studies and same-day interventions, along with strict medical necessity criteria for venous ablation procedures, create significant denial risk without specialty-specific billing controls.

A vascular medicine visit often combines an office evaluation with same-day non-invasive testing such as ankle-brachial index (ABI) studies or duplex ultrasound, and may proceed directly to a peripheral vascular intervention if findings warrant. Each of these components carries its own coding rules, frequency limits, and bundling edits, while venous insufficiency procedures such as endovenous ablation require documented conservative therapy trials and reflux duration thresholds before payers will authorize treatment.

The cost of generic billing

You went into vascular medicine to treat patients, not to chase claims

These are the places vascular medicine practices most often lose revenue when their billing platform wasn’t built for the work. Unlimited Systems closes each one with rules configured for your specialty.

Review your workflow

Common vascular medicine revenue leaks

Bundling denials when vascular lab testing (ABI, duplex ultrasound) is billed on the same day as a related peripheral vascular intervention without proper modifiers.
Prior authorization denials for venous insufficiency procedures (endovenous ablation) when conservative therapy trial documentation is incomplete.
Underbilling of peripheral vascular intervention codes when atherectomy, angioplasty, and stenting are performed in the same vascular territory without correct hierarchy sequencing.
Anticoagulation management billing gaps when chronic care management or INR monitoring services are not separately captured from E/M visits.

Challenges we solve for vascular medicine

The work that generic platforms leave to your staff is the work vascular medicine margin actually turns on.

Still evaluating

Not Ready to Switch Yet? That's Exactly When to Start the Conversation.

You don't have to be actively replacing your current system to have a useful conversation with Unlimited Systems. Many specialty practices talk with us months before a contract renewal, system evaluation, or operational change so they can understand where revenue leakage, denial risk, prior authorization delays, and reporting gaps may already be showing up.

Get a Demo Benchmark Your Current Workflow

You don't have to wait until your contract is up to start evaluating your options. The best time to assess your revenue cycle technology is before renewal pressure begins. Unlimited Systems can help you understand where your current workflows may be creating avoidable denials, manual work, charge capture gaps, or reporting limitations, so you're better prepared for renewal, replacement, or future planning.
