Pulmonology Billing Services
Pulmonology billing services for bronchoscopy, sleep studies, pulmonary function tests, and respiratory disease management.
What Pulmonology Billing Covers
Pulmonology spans office evaluation, function testing, procedures and sleep medicine, each with separate documentation rules. Testing requires documented interpretation, and equipment supplied to patients falls under different requirements again.
- Function testing billed with documented interpretation
- Bronchoscopy and procedural services coded from the report
- Sleep study components billed per setting and arrangement
- Equipment supplied to patients handled under its own rules
Pulmonology Billing Services Explained
Pulmonology billing covers bronchoscopy procedures, pulmonary function testing, sleep medicine billing, and complex E/M coding for chronic respiratory disease management. Bronchoscopy CPT codes vary by whether the procedure was diagnostic or included interventions, and pulmonary function testing codes distinguish between simple spirometry and complex comprehensive PFT panels. CMS covers home sleep testing under specific diagnostic criteria.
Medsure RCS manages pulmonology medical billing for Florida practices with coders experienced in bronchoscopy procedure coding, sleep study billing, and the HCPCS coding requirements for home oxygen and durable medical equipment orders that are a routine part of pulmonology practice. Pulmonology is part of our specialty medical billing program.
How It Works: Step by Step
Procedure Documentation Review
Bronchoscopy reports are reviewed for procedure type (diagnostic vs interventional), findings, and whether biopsy, lavage, or other interventional components were performed.
PFT Battery Selection
Pulmonary function test codes are selected based on the specific tests performed, spirometry, lung volumes, diffusion capacity, and bronchodilator response, not as a bundled panel.
Sleep Study Code Assignment
Sleep study codes are selected based on whether the study was attended (in-facility) or unattended (home), and the type of monitoring performed (polysomnography, limited, APAP titration).
DME and Oxygen Billing Coordination
Home oxygen and CPAP/BiPAP equipment billing is coordinated with the certifying physician's clinical documentation and compliance with Medicare coverage criteria.
Why This Matters for Your Revenue Cycle
Pulmonology procedure-specific coding accuracy drives first-pass acceptance above 95%.
Each PFT component is billed individually based on the actual battery performed, not as a default panel.
Bronchoscopy and PFT claims are submitted within 24 hours of procedure report receipt.
Every sleep study is correctly classified as attended or unattended with the appropriate monitoring level code.
Common Mistakes in Pulmonology Billing Services
Wrong Bronchoscopy Code for Interventional vs Diagnostic
Diagnostic bronchoscopy without biopsy (31622) is a different code from bronchoscopy with biopsy (31625), BAL (31624), or brushings (31623). Billing the diagnostic code when an intervention was performed results in systematic underpayment.
Billing a PFT Panel Code Instead of Individual Components
Pulmonary function testing does not have a single bundled panel code. Each component (94010 spirometry, 94727 nitrogen washout, 94726 plethysmography, 94729 diffusing capacity) is billed separately based on the actual tests performed. Estimating a panel results in either overbilling or underbilling.
Wrong Sleep Study Code for Home vs In-Facility
Type I PSG (attended, in-facility) uses different codes (95782-95811) than Type III-IV home sleep testing (95800-95806). Billing in-facility codes for home studies or vice versa results in denial based on place of service mismatch.
Missing CPAP Compliance Documentation for Re-Supply
Medicare requires documented CPAP compliance (4+ hours use per night on 70%+ of nights in a 30-day period) before covering CPAP supply replacements. Billing re-supply without compliance documentation in the record creates coverage denial risk.

Pulmonology Billing Services, Frequently Asked Questions
When a bronchoscopy includes both BAL (31624) and biopsy (31625), both intervention codes are billed. The bronchoscopy is not billed as a diagnostic procedure (31622) when interventions are performed, because the intervention codes include the bronchoscopy service. We review the procedure report to identify all interventions and bill the appropriate combination.
All PFT components performed on the date of service are billable in addition to the E/M visit. Modifier 25 is not required because PFT codes are not procedures in the same sense as surgical procedures. However, the clinical indication for each test must be documented separately in the note.
Initial CPAP setup uses HCPCS E0601 (CPAP device) plus A4604 (mask), A7030 (heated humidifier), and other supply codes. The physician's positive test result or diagnosis documentation is required to initiate coverage. Patient education is typically included in the E/M service rather than billed separately.
Home sleep apnea tests (HSAT) use codes 95800-95806 depending on the number of physiological channels measured. In-lab attended polysomnography uses 95782-95811 depending on patient age and the study type. Medicare requires a diagnosis of suspected OSA before covering HST, and will not cover both a home test and an in-lab study for the same initial diagnostic evaluation.
