Specialty billing · Pulmonology & Critical Care
Four rulebooks, colliding on one date of service.
Get more of every pulmonary function test, bronchoscopy, and critical-care minute paid on the first pass with pulmonology billing services from 247 Medical Billing Services. Since 2005 we have run the full revenue cycle across Medicare, Medicaid, and commercial payers, backed by a dedicated account manager, a free 360° reporting dashboard, and HIPAA and SOC 2 Type II compliance.
More than almost any other office specialty, pulmonology revenue turns on a single question the payer asks of every diagnostic line: who owns the equipment, and who read the study? That is the professional/technical split, and it is where most pulmonary function testing quietly underpays.
A spirometry or diffusing-capacity study performed on equipment you own and interpret should capture the global service; the same study performed in a hospital you don't own earns only the professional interpretation, reported with modifier 26.
Send the global code from a facility setting and you invite a recoupment; report only the interpretation when you owned the machine and you leave the technical dollars on the table.
Layer on top of that the bronchoscopy family with its endoscopy-reduction math, time-based critical care with its bundled components, and coverage-gated sleep, rehab, and home-oxygen services, and you have four distinct rulebooks colliding on claims that often share the same date of service. We code each moving part to what actually happened — nothing bundled away, nothing left uncaptured, nothing billed in a way that invites a takeback.
We report the diagnostic base and the specific add-ons instead of stacking them, and we apply the multiple-endoscopy payment reduction correctly. That way the session pays to its true value without tripping an unbundling edit.
Code families are noted here for precision:
| Where money is won or lost | What it is | What we manage |
|---|---|---|
| Pulmonary function testing (94010–94799) | Spirometry, bronchodilator response, lung volumes, diffusing capacity, and plethysmography, each with a professional and technical component | Correct global vs. component billing, modifier 26 or TC applied to your actual setting, and bundling edits between related tests respected |
| Bronchoscopy (31622–31654) | Diagnostic base plus lavage, biopsy, EBUS, and navigational add-ons | Right base code and add-ons, multiple-endoscopy reduction applied correctly, and no unbundling of components already included |
| Critical care (99291, 99292) | Time-based service with many bundled components | Total minutes documented, base and add-on units reported to time, and bundled services never billed separately |
| Ventilator and pulmonary management (94002–94005) | Ventilator management across inpatient, subsequent, and other settings | Reported only where it is separately payable and never inside a same-day critical-care period that already includes it |
| Sleep studies (95806–95811) | Attended polysomnography, CPAP titration, and home sleep testing | Correct study code for the setting, medical-necessity and titration rules met, and the right professional component captured |
| Pulmonary rehab and home oxygen (G0424, oxygen HCPCS) | Rehab sessions and home-oxygen equipment | Session caps and diagnosis rules tracked, and oxygen claims backed by the qualifying test and documented need |
Ask any pulmonary group where the money goes and the answers cluster around the same failure points — the split billed wrong, the endoscopy rule ignored, the minutes undocumented, the coverage test missing. Each one is preventable at the front end, before it becomes a denial or a post-payment recoupment. Procedure and coverage codes are noted here for precision:
Global PFT billed when only the interpretation is owed (94010–94799 without modifier 26)
Overpayment recoupment and audit exposure
We bill the professional component with modifier 26 in facility settings and the global code only where you own the equipment
Bronchoscopy add-ons stacked or the multiple-endoscopy rule ignored (31622–31654)
Unbundling denial or lost revenue
We report the correct base and add-ons and apply the endoscopy reduction so the session pays accurately
Ventilator management billed inside a same-day critical-care period (94002–94005 with 99291)
Duplicate-service denial
We keep ventilator management, blood-gas, and imaging review inside the critical-care bundle
Critical-care time reported without documented minutes (99291, 99292)
Downcode or takeback
We require documented total time and report base and add-on units to the minutes on the record
Same-day E/M billed with a procedure but no modifier 25
E/M denial
We append modifier 25 only when the visit is genuinely separate and significant from the procedure
Home oxygen or pulmonary rehab (G0424) without the qualifying test or session tracking
Medical-necessity denial
We confirm the qualifying blood gas or oximetry and track rehab session caps before submission
Every one of these is caught before submission rather than argued after the fact. Request a revenue review and we'll show you which of them is hitting your remits right now.
Pulmonology is a specialty where the coding knowledge that protects your revenue is unusually deep and unusually perishable. The technical/professional split shifts with your place of service, the endoscopy reduction depends on which bronchoscopy add-ons ran together, critical-care time has to be defended minute by minute, and the coverage policies behind oxygen, rehab, and sleep testing are rewritten more often than most practices can track.
When one in-house biller carries all of that alone, a single vacancy, an unfamiliar payer edit, or a busy testing week is enough to start losing money that never shows up as an obvious denial — it shows up as PFTs that pay a little light and critical-care claims that quietly downcode.
To outsource pulmonology billing services to a dedicated team is to replace that single point of failure with a bench of certified coders who see the same PFT splits, EBUS sessions, and ventilator-management edits across dozens of pulmonary practices every week. You trade the fixed overhead of hiring, training, and covering an in-house biller for a transaction-based model that scales with your volume, and you get a named account manager plus a live dashboard so the arrangement is transparent rather than a black box. For most groups the recovered revenue on testing and critical care alone outweighs the fee — which is exactly why smaller practices, where every underpaid study is felt immediately, often benefit the most.
Everything it takes to move a pulmonology claim from the encounter to paid, run by one certified team rather than split across vendors:
Spirometry, bronchodilator, lung-volume, diffusing-capacity, and plethysmography testing coded to the correct global or component split, with modifier 26 and TC applied to your actual place of service and inter-test bundling edits enforced before the claim goes out.
Diagnostic and interventional bronchoscopy reported to the right base code and add-ons, with the multiple-endoscopy rule and EBUS and navigational logic handled so the session pays to its true value.
Total critical-care minutes documented and reported to time, with ventilator management, blood-gas interpretation, and same-day imaging review kept inside the bundle instead of denying as duplicate charges.
AAPC- and AHIMA-credentialed coders assign diagnosis and procedure codes straight from the documentation, so the story on the claim matches the story in the chart.
Pulmonologists, intensivists, physician assistants, and nurse practitioners enrolled and re-credentialed so nothing rejects on provider eligibility.
Bundling, component-split, medical-necessity, and time-documentation denials appealed inside each payer's clock, not written off.
Old balances pursued relentlessly across Medicare, commercial, and Medicaid payers, including the DME contractors that adjudicate home-oxygen claims.
If you'd rather keep pulmonology billing and coding services under one roof, that's exactly the model — certified coders and billers on the same team, sharing the same record, instead of handing your claims back and forth between companies.

Choosing us is not hiring a general biller who happens to accept pulmonology claims. It's partnering with a pulmonology billing services company that already knows where pulmonary and critical-care revenue leaks and how to seal it before the claim is even built:
Every pulmonary function test is billed to the correct global or component split with the right modifier for where it was performed, so high-volume testing stops underpaying and stops drawing recoupments.
The base code, the add-ons, and the multiple-endoscopy reduction are applied correctly, so interventional sessions neither lose revenue nor bounce for unbundling.
Minutes are documented and reported to the correct base and add-on units, and the services bundled into critical care are never billed twice — so the time you actually spent is the time you're actually paid for.
Home-oxygen qualifying tests, pulmonary-rehab session caps, and sleep-study medical necessity are confirmed up front, so those claims pay instead of stalling in a coverage queue.
A named account manager owns your account and a free 360° dashboard shows every claim, denial, and dollar — with no long-term lock-in holding you there.
Typically see these numbers, month after month:
Every claim is scrubbed and filed within 24 hours, so revenue that used to sit in a work queue starts landing in your account instead.
A generalist learns pulmonology on your claims. We arrive already fluent in it — and the difference shows up on the remittance:
The rules shift with the setting and the patient mix, and we bill each one to the detail it demands:
Combined office, testing, and hospital work where PFT splits, critical-care time, and same-day modifier logic all decide the month's collections.
What decides the moneySplits, minutes and same-day modifiers
High procedure volume across diagnostic and interventional bronchoscopy, EBUS, and navigational work, where base-plus-add-on coding and the endoscopy rule govern the payment.
What decides the moneyBase-plus-add-on and the endoscopy rule
Attended and home sleep testing and CPAP titration, where setting, medical necessity, and the professional component drive clean payment; see our related sleep disorder billing for practices built primarily around sleep studies.
What decides the moneySetting, necessity and the component
Critical-care and ventilator management under strict time-documentation and bundling rules, billed for the minutes actually spent.
What decides the moneyThe minutes actually documented
Session-capped rehab and DME-adjudicated oxygen claims that live or die on qualifying tests and coverage policy.
What decides the moneyThe qualifying test and the session cap
Cardiopulmonary and shared-testing work that crosses specialties; our cardiology billing services cover that side of the practice.
What decides the moneyEach side on its own rulebook
Changing billers shouldn't mean a gap in cash flow, and with us it doesn't.
We work inside your existing practice-management and EHR systems, so nobody has to relearn a platform.
Credentialing and payer-enrollment review run in parallel while your claims keep going out the door, a named account manager leads the transition from day one, and most pulmonology practices are fully live within a few weeks.
Because there's no long-term contract, we earn the relationship every month rather than lock you into it.
The denial drop and the faster A/R show up in the first cycles, not a quarter later.
You collect on the services that most often slip through unnoticed.
The split pulmonary function test, the endoscopy-reduced bronchoscopy session, the documented critical-care minutes, and the coverage-gated oxygen and rehab claim. Each carries a decision the payer scrutinizes, and getting one wrong either underpays you now or triggers a takeback months later. We build your pulmonology billing around those exact decision points, not a generic charge-entry workflow: charges are scrubbed against payer-specific edits the same day the encounter closes, chart detail is matched before anything transmits, and the place-of-service splits, bundling logic, and time documentation are checked at the front end. Since 2005 that discipline has produced first-pass clean claims near 99%, denials down up to 40%, and days in A/R under 25. Seal the leaks before the claim is even built
The pulmonology billing services provider you want is the one that already knows where pulmonary revenue leaks — not the one that learns on your remits. 247MBS is the former.
What changes hands
Outsource pulmonology billing to 247MBS and you replace a single in-house point of failure with a bench of certified coders who see the same PFT splits, EBUS sessions, and ventilator-management edits across dozens of pulmonary practices every week — so unfamiliar payer edits get caught the first time, not after they have cost you.
Outsourcing pulmonology billing services here means the technical/professional split, the endoscopy reduction, and defended critical-care time are simply handled, month after month, while your physicians stay with patients instead of remits.
And pulmonology billing services outsourcing with us is never a black box: a named account manager owns the relationship and a free 360° dashboard shows every claim, denial, and dollar in real time. You trade the fixed overhead of hiring, training, and covering a biller for a transaction-based model that scales with your volume — and for most groups the recovered revenue on testing and critical care more than covers the fee.
