What the PulmOne MiniBox+ Can Do
A complete, cabinless pulmonary function testing platform engineered for accuracy, efficiency, and modern ambulatory workflows. MiniBox+ consolidates the full PFT suite into a compact desktop system—no body box, no gas cylinders, no dedicated testing room.
Spirometry (Baseline)
Measures FVC, FEV1, FEV1/FVC, and complete expiratory flow parameters using high‑precision digital sensors. Supports ATS/ERS standards for repeatability and quality grading.
Pre‑ & Post‑Bronchodilator Spirometry
Performs bronchodilator responsiveness testing with automated pre/post comparison, trending, and interpretation. Enables CPT 94060 billing for reversible airway obstruction evaluation.
Lung‑Volume Measurement
Cabinless lung‑volume determination using proprietary flow‑interruption technology. Measures TLC, RV, FRC, and thoracic gas volume without a body box—typically completed in under 60 seconds of tidal breathing.
DLCO (Diffusing Capacity)
Automated single‑breath diffusing‑capacity testing to assess gas‑exchange efficiency. Supports CPT 94729 and integrates real‑time quality control and calibration checks.
Flow‑Volume Loop Testing
Captures inspiratory and expiratory loops for upper‑airway obstruction assessment. Provides detailed curve morphology analysis and ATS/ERS‑aligned quality indicators.
Complete PFT Panel
Combines spirometry, lung volumes, and DLCO into a single complete‑PFT workflow. Supports the most common Medicare‑recognized combination: 94060 + 94726 + 94729.
Cabinless, Gas‑Free Operation
No body box, no gas cylinders, no specialized ventilation. MiniBox+ operates in any standard exam room and requires minimal setup or environmental control.
Automated Interpretation & Reporting
Generates structured, physician‑ready reports with predicted values, LLN, Z‑scores, and trend analysis. Integrates with EMR systems for seamless documentation.
Portable Desktop Footprint
Weighs under 18 lbs and fits on any clinical workstation. Designed for multi‑room workflows and high‑volume pulmonary or primary‑care environments.
MiniBox+ Reimbursement & ROI Model
PulmOne identifies the following reimbursement figures as 2025 Medicare Physician Fee Schedule national amounts. CMS advises verifying current rates by year, locality, and service setting. Actual payment varies by region, facility status, and payer contract.

Most Common Complete‑PFT Billing Combination
| CPT Code | Component | 2025 Published Amount* |
|---|---|---|
| 94060 | Pre‑ and post‑bronchodilator spirometry | $37.85 |
| 94726 | Lung‑volume determination | $54.99 |
| 94729 | DLCO testing | $54.34 |
| Combined published allowable | $147.18 | |
PulmOne identifies 94060 + 94726 + 94729 as the most frequent combination used for a complete PFT when evaluating symptoms such as dyspnea or shortness of breath. Medical necessity and payer‑specific requirements apply.
Important Billing Rules
| Billing Issue | Guidance |
|---|---|
| 94010 and 94060 | Generally should not be billed together; 94060 already includes baseline spirometry. |
| NCCI edits | Procedure‑to‑procedure edits may deny one code. Use modifiers only when services are distinct and permitted. |
| Local reimbursement | National figures are estimates. Payment varies by locality, facility setting, and provider status. |
| Commercial insurance | Reimbursement differs by payer contract and coverage policy. |
| Coverage & medical necessity | Diagnosis support, documentation, test performance, interpretation, and recordkeeping must meet MAC or payer policy. |
CMS updates NCCI edits quarterly. For an edit pair reported on the same date, the column‑two service is generally denied unless a clinically appropriate modifier is allowed and supported.

Why Complete PFT Testing Outperforms 94010 & 94060 — For Practices and Patients
MiniBox+ enables full-suite pulmonary testing—spirometry, lung volumes, and DLCO—in one visit. This expands diagnostic accuracy, improves patient outcomes, and significantly increases allowable reimbursement compared to performing only baseline or bronchodilator spirometry.
Higher Reimbursement Than 94010 or 94060 Alone
Baseline spirometry (94010) reimburses $26.52. Bronchodilator responsiveness (94060) reimburses $37.85. A complete PFT panel—94060 + 94726 + 94729—totals $147.18.
MiniBox+ unlocks lung volumes and DLCO, adding $109.33 beyond spirometry alone.
More Complete Clinical Insight
Spirometry alone cannot diagnose restrictive disease, diffusion impairment, or early interstitial changes. MiniBox+ adds lung volumes and DLCO—critical for evaluating dyspnea and complex pulmonary pathology.
Providers identify conditions that would otherwise be missed with 94010 or 94060 alone.
Better Patient Experience
MiniBox+ is cabinless, quiet, and non‑claustrophobic—no body box, no gas cylinders. Lung‑volume testing takes under 60 seconds of relaxed breathing.
Patients experience less anxiety and greater comfort during testing.
Faster Diagnosis & Reduced Referrals
Without MiniBox+, patients wait weeks for hospital-based PFT labs. In‑office complete PFTs accelerate diagnosis and keep care—and revenue—inside the practice.
Patients receive answers sooner, improving continuity of care.
One Device, One Visit, Complete Evaluation
MiniBox+ consolidates spirometry, lung volumes, and DLCO into a single workflow. Practices avoid fragmented testing and repeated visits.
The result: higher diagnostic accuracy and streamlined operations.
Better Care = Better Outcomes
Comprehensive PFTs allow earlier detection of restrictive disease, impaired diffusion capacity, and mixed ventilatory defects.
MiniBox+ elevates the standard of care beyond what spirometry alone can provide.

Who the PulmOne MiniBox+ Is Built For
MiniBox+ is engineered for offices that routinely evaluate asthma, COPD, unexplained dyspnea, restrictive lung disease, chronic cough, and treatment response—and currently refer patients elsewhere for complete pulmonary function testing. These organizations gain the strongest clinical and financial lift from bringing full PFT capability in‑house.
Pulmonology Practices
The clearest target. Pulmonologists routinely require spirometry, lung volumes, and DLCO for COPD, pulmonary fibrosis, emphysema, mixed obstructive/restrictive disease, and chronic dyspnea. MiniBox+ delivers complete PFTs without a body box.
Allergy & Immunology Practices
Ideal for moderate‑to‑severe asthma, chronic cough, allergic respiratory disease, and patients whose spirometry appears normal despite persistent symptoms. Lung volumes reveal air trapping; DLCO identifies deeper abnormalities.
Multispecialty Groups with Pulmonology or Allergy
Centralize testing, reduce outside referrals, support multiple providers, and generate the volume needed to maximize ROI.
Hospital Outpatient Pulmonary Departments
Perfect where body‑box labs are too large, expensive, or difficult for certain patients. PulmOne identifies outpatient departments as a core target.
Independent Diagnostic Testing Facilities
Excellent for respiratory diagnostics across multiple referring physicians. MiniBox+ offers portability, faster throughput, and reduced infrastructure.
Pediatric Pulmonology & Pediatric Allergy
Tests children beginning at age five. Cabinless design is far more comfortable for anxious or body‑box‑intolerant pediatric patients.
Occupational Medicine Clinics
Useful for respiratory surveillance of workers exposed to dust, chemicals, fumes, silica, asbestos, or industrial hazards. Strongest fit when recurring employer contracts generate consistent volume.
Interstitial Lung Disease & Pulmonary Fibrosis Clinics
DLCO and lung‑volume testing are essential for restrictive disease and impaired gas transfer. Common in pulmonology groups and academic outpatient centers.
COPD & Smoking‑Cessation Clinics
Full PFT capabilities characterize obstruction, hyperinflation, and gas‑exchange impairment far beyond basic spirometry.
Preoperative Evaluation Clinics
Ideal for thoracic, bariatric, transplant, and cardiopulmonary surgical risk assessment—when volume and clinical oversight are sufficient.
Mobile Diagnostic & Respiratory Testing Companies
At ~18 lbs, MiniBox+ is built for portable use across satellite offices and multi‑location service models.
Skilled Nursing, Rehab & Home‑Based Specialty Programs
Cabinless design accommodates wheelchair‑bound, obese, mobility‑limited, or bedridden patients. Economics depend heavily on volume and payer coverage.
Eirionyx Member Advantage
Eirionyx client members in the United States and Canada receive exclusive partner‑level discounts on PulmOne MiniBox+ systems, service packages, and onboarding support.
