Keep authorization and coverage aligned before the appointment is booked.
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.

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.
Specialty rules and connected data keep your team focused on the exceptions that need judgment.
Coverage and authorization stay tied to the order.
Code, unit, and modifier checks happen before filing.

Walk the workflow with usOur 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.
