When a pulmonology practice starts looking for medical billing services, the search quickly reveals dozens of options — large national RCM companies, regional billing firms, specialty-focused boutiques, and technology-driven platforms. Most of them will tell you they can handle pulmonology billing. Fewer of them actually can.
This guide is designed to help pulmonology practice owners, administrators, and physician partners understand what specialized pulmonary billing services should actually deliver, what separates a qualified vendor from a generalist that will struggle with your specialty’s complexity, and how to evaluate and select the right billing partner for your practice.
Why Pulmonology Requires Specialty Billing Expertise
Pulmonology is not a specialty where general medical billing knowledge transfers cleanly. The service mix — critical care, bronchoscopy, pulmonary function testing, ventilator management, pleural procedures, sleep study interpretation — involves coding rules, documentation requirements, and payer behaviors that a generalist billing team will not handle reliably.
Consider a typical week in a pulmonology practice: a physician provides critical care for ventilated ICU patients (requiring time-based coding with procedure exclusions), interprets pulmonary function test panels (requiring component coding and signed interpretation reports), performs bronchoscopy with EBUS-guided sampling (requiring primary codes and multiple add-on codes with correct modifiers), and manages an outpatient panel of COPD and ILD patients (requiring diagnosis coding to the highest specificity for HCC capture in Medicare Advantage patients).
Each of these service types has its own compliance requirements. A billing partner that cannot navigate all of them accurately will produce a revenue cycle that consistently underperforms — with coding errors that reduce collections, documentation gaps that trigger denials, and compliance exposures that create audit risk.
The right pulmonology billing service is not just a billing service — it is a specialty-specific revenue cycle partner with deep knowledge of how pulmonary medicine is coded, documented, and reimbursed.
Core Services a Qualified Pulmonary Billing Company Should Provide
Not all billing companies offer the same scope of services. When evaluating a potential partner, confirm that the following services are included:
Charge Capture and Review
The billing company should review all charges — ideally before submission — to verify that the codes submitted accurately reflect the services documented. This is not a passive function. A qualified billing team will identify missing add-on codes for bronchoscopy procedures, flag critical care claims where the documented time doesn’t match the billed units, and catch PFT claims where the interpretation documentation is insufficient.
Coding
The billing company’s coders should hold recognized credentials — CPC (Certified Professional Coder), CCS (Certified Coding Specialist), or specialty-specific credentials — and should have demonstrated experience with pulmonary and critical care coding specifically. Ask about their coder training program and how they keep staff current on annual regulatory changes.
Claims Submission
Claims should be submitted electronically to all payers, typically within 3–5 business days of the service date. The billing company should use a clearinghouse with specialty-specific claim edits that validate claims before submission. Clean claim rates — the percentage of claims accepted on first submission — should consistently exceed 95%.
Denial Management
This is where the difference between a specialist billing partner and a generalist becomes most visible. Critical care denials, bronchoscopy bundling denials, and PFT medical necessity denials all require specialty-specific appeal language and documentation support to reverse effectively. A billing company that handles these denials with generic appeal templates will have low first-pass resolution rates.
Ask potential vendors for their denial rate and first-pass appeal success rate for pulmonology clients specifically. Compare those numbers to industry benchmarks (denial rate below 8%, first-pass resolution above 70%).
Payment Posting and Reconciliation
All payments — including ERA payments, paper check payments, and patient payments — should be posted accurately and promptly. The billing company should flag underpayments (payments below contracted rates) and pursue corrections with payers.
Reporting and Analytics
You should receive regular, detailed reporting on your practice’s financial performance: net collection rate, denial rate by category, days in A/R, A/R aging, monthly collections trend, and payer-specific performance. Reporting should be specific enough that you can identify where problems are occurring — not just summary metrics that mask underlying issues.
Patient Billing and Collections
Patient financial responsibility has grown significantly with the spread of high-deductible health plans. The billing company should manage patient statements, payment plans, and soft-collections processes in a way that is professional, compliant with HIPAA and FDCPA, and effective at recovering patient balances.
What Separates a Specialty Pulmonary Billing Service from a Generalist
The practical differences between a specialty-trained pulmonary billing team and a generalist team show up in specific, measurable ways:
Critical care coding accuracy. A specialty team will correctly apply time-based critical care codes (99291, 99292), exclude procedure time from the critical care total, and flag notes where time documentation is missing before the claim is submitted. A generalist team will apply the codes mechanically based on what the physician wrote on the charge sheet, without the clinical knowledge to verify whether the coding is accurate or the documentation is sufficient.
Bronchoscopy add-on capture. A specialty team will verify that all add-on codes appropriate to the documented procedure are captured — BAL, transbronchial biopsy, EBUS-guided sampling, fluoroscopy guidance — and will apply the correct modifiers for bilateral or multiple procedures. A generalist team will bill what was on the charge sheet and miss add-on codes that were performed but not explicitly listed.
PFT component billing. A specialty team will understand the distinction between global PFT billing (in an office-based practice that owns the equipment) and professional component billing (in a hospital outpatient setting), and will apply the correct billing approach for each setting. A generalist team may apply the same billing approach regardless of setting, resulting in denials or underpayments.
Payer-specific knowledge. A specialty team that handles a large volume of pulmonary practices will have accumulated payer-specific knowledge — which Medicare Administrative Contractor (MAC) policies apply to EBUS billing, which commercial plans require prior authorization for PFT panels, which Medicare Advantage plans routinely deny critical care claims — that a generalist team cannot match.
Evaluating Pulmonology Billing Services: A Practical Framework
When you are ready to evaluate billing companies, use this framework to structure your due diligence:
Step 1: Assess Specialty Experience
Request a specific accounting of the vendor’s experience with pulmonology billing:
- How many active pulmonology clients do they currently serve?
- What is the service mix of those clients (office-based, hospital-based, critical care-heavy, procedure-heavy)?
- Can they provide three client references from pulmonology practices with a similar size and service mix to yours?
A vendor that cannot point to a meaningful track record with pulmonology clients specifically — not “internal medicine and related specialties” — is not a specialty billing partner. They are a generalist who is willing to try.
Step 2: Evaluate Coding Competency
Ask for a coding competency assessment:
- What credentials do their pulmonology coders hold?
- How do they handle annual CPT and ICD-10 updates — what is their training and implementation process?
- Can they walk you through how they would code a complex bronchoscopy case (e.g., flexible bronchoscopy with BAL, transbronchial biopsy × 2 lobes, and EBUS-guided sampling of a mediastinal lymph node)?
The answer to that last question will tell you a great deal. A vendor with genuine coding expertise will walk through the primary code, the applicable add-on codes, the lobe-specific billing for transbronchial biopsies, and the EBUS code — accurately and without hesitation. A vendor without that expertise will give a vague or incorrect answer.
Step 3: Review Compliance Infrastructure
A billing partner that lacks compliance infrastructure creates compliance risk for your practice, not just for their own business. Ask:
- Do they conduct regular coding audits of their own work? How often, and at what sample size?
- How do they communicate audit findings to clients?
- What is their process when an audit identifies a systematic coding error?
- Can they provide a sample compliance audit report from a pulmonology client (redacted for client confidentiality)?
Step 4: Evaluate Reporting Transparency
Request sample reports. Specifically, ask to see:
- A monthly performance dashboard
- A denial analysis report showing denial rates by code and denial reason
- An A/R aging report
- A year-over-year collections trend report
If the vendor’s reports are limited to basic summary metrics — total charges, total collections, collection percentage — that is a warning sign. A sophisticated billing partner should be able to show you exactly where your revenue is and where it is not.
Step 5: Understand the Contract Terms
Before signing any agreement, review:
- The fee structure (percentage of collections is most common; confirm what is included in the percentage and what is billed separately)
- The contract term and notice required for termination
- Performance guarantees, if any, and remedies if guarantees are not met
- Data ownership — your patient data and billing records are yours; confirm you can retrieve them if you change vendors
- Transition provisions — what happens to claims in process if you terminate the relationship
A vendor that resists reasonable contract terms — particularly around data ownership and termination rights — is a vendor to avoid.
What to Expect from the Onboarding Process
A thorough onboarding process is a sign of a serious billing partner. Expect:
Credentialing verification. The billing company will verify that all of your physicians and APPs are properly credentialed and enrolled with all relevant payers. This process takes time — begin it early to avoid gaps in billing after the transition.
Practice workflow review. A quality partner will assess your existing charge capture process, EHR setup, and documentation workflows before taking over billing. They should identify gaps and make specific recommendations for improvement.
Fee schedule review. The billing company should review your existing payer contracts and fee schedules and identify any that are significantly below market rates. This is an opportunity to renegotiate contracts before the new billing relationship begins.
Staff training. Expect some training sessions for your clinical and administrative staff — on charge capture procedures, documentation requirements, and communication protocols with the billing team.
A vendor that rushes through onboarding to start billing as quickly as possible is more interested in the revenue than in setting the relationship up for success.
Red Flags to Watch For
The following are warning signs that a billing company is not the right partner for a pulmonology practice:
- They cannot name specific pulmonology clients as references
- Their coders’ credentials are not verifiable or do not include relevant certifications
- They offer a fee that seems significantly below market (4–7% is typical for specialty billing; anything below 3% should prompt questions about what is being excluded or where quality is being cut)
- Their reporting is limited and does not include denial analytics
- They cannot explain how they handle critical care time documentation review or bronchoscopy add-on coding
- They resist contract terms around data ownership or reasonable termination rights
- They promise dramatic collection rate improvements without conducting a thorough assessment of your current performance
The Bottom Line
Finding the right pulmonology medical billing service is worth the time and diligence required. The right partner will increase your collections, reduce your compliance exposure, eliminate the operational burden of managing an in-house billing function, and provide the specialty expertise that your complex service mix demands.
The wrong partner will produce the same results your current situation does — or worse — while adding the communication friction and reduced control that come with outsourcing.
The difference between a good billing partner and a mediocre one, in a pulmonology practice generating $3 million in annual collections, can easily exceed $200,000 in annual revenue impact. That makes the selection process one of the most financially significant decisions your practice can make.
Frequently Asked Questions
What services should a pulmonology medical billing company provide?
A full-service pulmonology billing partner should provide: charge capture review and coding accuracy verification, clean claims submission with specialty-specific claim scrubbing, denial management with specialty-aware appeal language, payment posting and underpayment identification, patient billing and collections, regular performance reporting (net collection rate, denial rate, A/R aging), and compliance support including internal coding audits and regulatory update implementation.
How do I know if a billing company has real pulmonology experience?
Ask specifically: How many active pulmonology clients do you currently serve? Can you provide references from practices with critical care, bronchoscopy, and PFT billing? Walk me through how you would code a bronchoscopy with BAL, transbronchial biopsy, and EBUS-guided sampling. A vendor with genuine expertise will answer the last question accurately and specifically. A generalist will give a vague or incomplete answer.
What does a pulmonology billing service typically cost?
Most pulmonology billing services charge a percentage of net collections — typically 4–7% for a full-service arrangement. Some vendors charge per-claim fees instead. Percentage-based billing aligns the vendor’s incentive with your collections performance. Be cautious of fees significantly below 4% — they often exclude denial management, payment posting, or other services that are quoted separately. Understand exactly what is included before comparing fee quotes.
How long does it take to transition to a new pulmonology billing service?
A well-managed transition typically takes 30–60 days from contract signing to full operation. The onboarding process includes credentialing verification, payer enrollment review, EHR integration or workflow setup, and staff training. Cash flow should be relatively stable during this period if the transition is planned carefully. Running the new vendor parallel to your existing team for 30 days, if feasible, provides additional safety during the handoff.
What metrics should I use to evaluate a pulmonology billing service’s performance?
The key performance indicators to track monthly are: net collection rate (target ≥95%), denial rate (target ≤8%), clean claim rate (target ≥96%), days in A/R (target ≤40), first-pass resolution rate for denied claims (target ≥70%), and A/R over 90 days as a percentage of total A/R (target ≤15%). Require these metrics in your monthly reporting and review them in your regular performance calls with the billing partner.
What red flags should I watch for when evaluating pulmonology billing companies?
Red flags include: inability to name specific pulmonology client references, vague or incorrect answers to specialty-specific coding questions, fees significantly below market that suggest excluded services, reporting limited to basic summary metrics without denial analytics, resistance to contract terms around data ownership or termination rights, and promises of dramatic collection improvements without a thorough assessment of your current performance.
Can a pulmonology billing service help with payer contract negotiations?
Many full-service pulmonology billing companies offer contract analysis and negotiation support as an additional service. This typically involves benchmarking your current contracted rates against market data for your region and specialty, identifying payers where your rates are significantly below market, and either directly negotiating on your behalf or preparing data and language for your own negotiations. For practices with below-market contracts, this service can deliver substantial long-term revenue improvement.
