Optimize vascular lab testing, peripheral intervention coding, and venous insufficiency authorizations. See why vascular medicine practices choose Unlimited Systems for practice management and RCM software.
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.

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.

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

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.
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.
That concern is valid, specialty practice operations are too important to disrupt. A conversation with Unlimited Systems doesn't mean an immediate rip-and-replace. We help teams evaluate workflows, identify gaps, and build a realistic path forward based on specialty, volume, payer mix, locations, integrations, and internal readiness.
Most specialty teams are already stretched thin. That's why the evaluation should focus on where the largest operational burden exists today, prior authorization, denials, charge capture, reporting, manual reconciliation, or payer-specific follow-up. The goal isn't to add work. It's to understand where better systems can remove it.
“Good enough” can still hide revenue leakage. Many practices aren't losing revenue because claims aren't being submitted, they're losing it through preventable denials, underpayments, missed modifiers, incomplete documentation, delayed authorizations, manual workarounds, and limited visibility into payer performance.
Unlimited Systems isn't designed to replace the expertise of your billing team. It's designed to give them better tools, cleaner workflows, better visibility, and fewer manual workarounds. Strong teams still need technology that helps them prioritize the right work, catch issues earlier, and reduce preventable rework.
Cash flow continuity is one of the biggest reasons to evaluate carefully and early. Unlimited Systems can help practices understand potential risk areas before a transition plan is ever built, including claim flow, authorizations, charge capture, payer rules, reporting, and operational dependencies.
Change management matters. The right platform should simplify daily work, not create unnecessary complexity. Unlimited Systems focuses on specialty workflows that align with how teams already manage authorizations, charges, denials, documentation, and financial follow-up.
Reporting is often the first visible symptom of a deeper workflow issue. If leadership can't clearly see denial trends, underpayments, authorization delays, payer behavior, or staff workload, it's harder to know what to fix. Unlimited Systems combines workflow tools with Power BI analytics to help leaders see where performance is improving and where revenue is still at risk.
That's a smart approach. A conversation with Unlimited Systems can help identify the financial case before a buying decision. Common areas to evaluate include denial reduction, staff efficiency, underpayment detection, charge capture improvement, prior authorization turnaround, and reduced manual reconciliation.
Specialty practices often depend on EHRs, clearinghouses, payment tools, drug workflows, and reporting systems. Unlimited Systems is designed to act as a connected financial workflow layer that helps reduce fragmentation, not add more disconnected work.
That caution is healthy. Automation should make decisions easier to see, not harder. Unlimited Systems is designed to surface why a claim is flagged, which payer rule applies, and where a human should step in, so your team stays in control while routine work is handled for them.
You don't need to be ready to buy to have a useful conversation. Many practices start by comparing their current workflows against what specialty-specific revenue cycle technology can support. That gives leadership a clearer view of what to fix now, what to plan for, and what questions to ask before the next renewal.

Non-invasive vascular lab studies (CPT 93922-93923 for ABI, 93880-93971 for duplex ultrasound) are coded based on the documented vessels and extremities studied, with our system tracking frequency limits per payer policy and ensuring the correct unilateral versus bilateral code is applied based on the documentation.
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.
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.
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.
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.
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.
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.
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.

That's putting it nicely based on what we hear every day.
A support line that never picks up. An overseas call center that's never heard of your account. Errors nobody catches until the denial shows up. We're Midwest-based, not offshore, and the team that answers already knows your account. Practices that switch tend to wish they'd done it sooner.
