Streamline pulmonary function testing, sleep study coding, and home oxygen DME documentation. See why pulmonology practices choose Unlimited Systems for practice management and RCM software.
Pulmonology practices manage a uniquely diverse billing portfolio spanning pulmonary function testing, diagnostic sleep studies, ventilator and home oxygen management, and complex chronic disease evaluation and management. Generic RCM platforms frequently fail to bundle PFT components correctly, miss DME documentation requirements for home oxygen, and mishandle the technical/professional splits inherent to sleep diagnostics, creating denial patterns that compound across a practice's highest-margin diagnostic services.
A comprehensive pulmonary function test session may include spirometry, lung volumes, diffusion capacity, and bronchodilator response testing, each with its own CPT code and bundling rules that vary by payer. Meanwhile, a patient prescribed home oxygen therapy requires documentation of qualifying blood gas or oximetry results, a detailed written order, and ongoing certification of medical necessity to satisfy DME MAC requirements; without this chain of documentation, oxygen equipment claims are denied outright and the referring pulmonologist's certification becomes a compliance liability.

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.

Each module is configured for the codes, modifiers, and payer rules pulmonology teams work with, not adapted from generic billing software.
These are the places pulmonology 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 pulmonology 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.

Our charge engine evaluates which PFT components were performed in a single session, spirometry, lung volumes, diffusion capacity, bronchodilator response, and applies payer-specific bundling rules to determine whether to bill a comprehensive panel code or itemized component codes, preventing partial-session denials.
Medicare requires qualifying blood gas or pulse oximetry results showing hypoxemia, a detailed written order, and an initial certificate of medical necessity with periodic recertification. Our system tracks each of these requirements per patient, blocking oxygen equipment claim submission until the full documentation chain is verified and current.
In-lab polysomnography (CPT 95810/95811) is typically billed as a global code when the practice owns the equipment and facility, or split into technical and professional components when a separate sleep lab is involved. Home sleep apnea tests (95800/95806/G0399) follow different technical/professional splitting rules based on equipment ownership, which our engine determines automatically.
When a diagnostic polysomnogram transitions to a CPAP titration study within the same overnight session, our engine identifies the split-night protocol from the sleep technologist's documentation and applies the correct combined CPT code (95811) rather than billing two separate incomplete studies.
Ventilator management codes (94002–94005) require documentation of time spent and place of service (inpatient, nursing facility, or home). Our system validates that documented time meets the code threshold and that the place-of-service code matches the billing location requirements for each ventilator management code.
Bronchoscopy procedures with biopsy, brushing, washing, or BAL components are billed according to NCCI bundling rules, with our engine automatically determining which additional procedures performed during the same bronchoscopy session can be billed separately versus which are bundled into the base procedure code.
Yes. Patients with COPD, asthma, or other chronic pulmonary conditions are flagged for chronic care management (CCM) and remote physiologic monitoring (RPM) billing eligibility, with the system tracking time and data review thresholds required for these codes.
Pulmonary rehabilitation (CPT 94625/94626) sessions are tracked against the Medicare lifetime session limit, with the system alerting staff before a patient exceeds covered session counts and ensuring qualifying diagnosis documentation supports each billed session.
