Specialty Billing
Pulmonology Medical Billing Services
Billing for pulmonary practices — PFT labs with component coding, bronchoscopy families, chronic disease programs, and the critical-care documentation hospital work demands.
Pulmonology revenue mixes office E/M for chronic respiratory disease, pulmonary function testing with multi-component coding, bronchoscopic procedures with add-on structures, and substantial hospital work — including critical care billing, where time documentation rules are strict and audits are routine.
Our pulmonology billing covers the full footprint: PFT components billed to what was actually performed, bronchoscopy claims constructed from procedure notes, critical-care time capture done defensibly, and chronic care programs (COPD management, home oxygen ordering) run to their documentation rules.
Why Pulmonology Billing Is Complex
PFT billing is component work — spirometry, lung volumes, diffusion capacity, and bronchodilator responsiveness each code separately with bundling relationships, and labs that bill a fixed panel regardless of what was performed create audit exposure. Critical care billing requires documented time and qualifying clinical conditions; it pays substantially better than standard hospital E/M and is scrutinized proportionally. Home oxygen and DME ordering rules put the pulmonologist’s documentation at the center of someone else’s claim, generating queries that consume staff time.
Common Service Categories We Bill
- Chronic respiratory disease management (COPD, asthma, ILD)
- Pulmonary function testing laboratories
- Bronchoscopy and advanced diagnostic procedures
- Hospital and critical care services
- Sleep-disordered breathing evaluation
Common Denial Causes in Pulmonology
- PFT component bundling and frequency edits
- Critical-care documentation reviews and downcodes
- Bronchoscopy add-on denials against procedure notes
- Medical-necessity denials on repeat imaging and testing
Documentation Risks to Watch
- PFT interpretations not documenting each billed component
- Critical care time not explicitly documented per date
- Oxygen qualification testing documentation incomplete for DME rules
Coding Considerations
- Critical care is time-based with explicit inclusion/exclusion rules for bundled services — the note must state qualifying time
- PFT panels should bill from performed-and-interpreted components, not standing lab defaults
Educational note: Coding and payer information on this page is general educational content, not definitive coding, legal, or reimbursement advice. CPT/ICD-10 rules and payer policies change frequently — verify specifics against current official sources and qualified professionals.
Typical Payer Challenges
- Frequency limits on repeat PFTs and imaging for chronic disease
- MA plan prior authorization spreading into diagnostics
Pulmonology Billing FAQs
Are we billing our PFT lab correctly?
The test is whether claims mirror performed components: a visit where only spirometry was done should not bill the full panel, and complete studies should not leave diffusion capacity unbilled. We audit a sample against interpretations, then set the charge tickets to component-level accuracy.
What makes critical care billing risky?
It pays meaningfully more than standard hospital E/M, so payers audit it: documented time must meet thresholds, the patient’s condition must qualify, and bundled services cannot double-bill. Done with disciplined documentation it is entirely defensible revenue — done casually it is a repayment finding waiting to happen.
