Common CPT Codes Reference

Key codes include 94010 (Spirometry, including graphic record, total and timed vital ), 94060 (Bronchodilation responsiveness testing, spirometry before an), 94726 (Plethysmography for determination of lung volumes), 94729 (Diffusing capacity, pulmonary (DLCO)), 31623 (Bronchoscopy, rigid or flexible; with brushings), 31625 (Bronchoscopy with biopsy(s) of bronchus or lung), 31641 (Bronchoscopy with placement of bronchial stent(s)), 94002 (Ventilation assist and management, hospital inpatient — init), 94003 (Ventilation assist and management — subsequent days), 99232 (Subsequent hospital care, moderate complexity). Proper code selection requires understanding of bundling rules, NCCI edits, and modifier usage.

Expert Billing Insights

COPD and Asthma Management Billing: Quality Metrics and Care Gaps

Pulmonology practices managing COPD and asthma have opportunities to capture CCM (Chronic Care Management) revenue, bill for inhaler technique training, and address quality measure gaps. HEDIS and CMS STAR measures for COPD and asthma include spirometry confirmation, appropriate controller medication use, and exacerbation prevention. Documenting these quality elements not only supports value-based reimbursement bonuses but also ensures comprehensive coding that reflects true case complexity.

• CCM (99490): bill monthly for COPD/asthma patients with 2+ chronic conditions
• COPD spirometry (94010 or 94060) should be performed and documented annually
• Inhaler technique training (94664): billable when performed by clinical staff with physician order
• Pulmonary rehab (PR): 94625 (physician services) + facility codes — require physician prescription

Bronchoscopy Coding: Diagnostic, Therapeutic, and Navigational

Bronchoscopy coding has expanded significantly with the introduction of advanced bronchoscopic techniques including navigational bronchoscopy (31656), EBUS (31652–31654), and thermal vapor ablation. Each technique has specific CPT codes and documentation requirements. When multiple procedures are performed during one bronchoscopy session, the most complex code is billed as the primary, with additional procedures using appropriate add-on codes. Pathology from biopsies is billed separately by the pathologist.

• EBUS with lymph node aspiration: 31652 (first station) + 31653 (additional stations)
• Navigational bronchoscopy: 31656 for bronchoscopic localization guidance
• Multiple biopsies in one bronchoscopy: 31625 covers all biopsies — not billed per site
• BAL (31624) can be added to diagnostic bronchoscopy but not when same-session biopsy is performed

Pulmonary Hypertension and ILD Billing: High-Complexity Management

Pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD) require high-complexity management that supports premium E/M coding. These patients are typically on multiple specialty medications (prostacyclins, endothelin receptor antagonists, PDE5 inhibitors, antifibrotic agents) with complex monitoring requirements. The high complexity of medical decision-making supports billing 99215 (outpatient) or 99233 (inpatient) at most visits, while REMS (Risk Evaluation and Mitigation Strategy) programs for dangerous drugs create additional documentation obligations.

• PAH medications on REMS programs: document program enrollment and prescribing compliance
• Right heart catheterization (93561) for PAH diagnosis — typically performed by cardiologist or interventional
• Nintedanib (Ofev) and pirfenidone (Esbriet) for ILD: prior auth requires PFT and HRCT documentation
• Oxygen prescription for PAH/ILD: CMS-484 CMN required; bill E1390-E1392 for concentrators

Payer-Specific Billing Tips

Medicare

• COPD low-dose CT screening (G0297): covered annually for high-risk smokers 50–80 per USPSTF
• Smoking cessation counseling: 99406 (3–10 min) and 99407 (10+ min) — 8 sessions per year covered
• Home oxygen coverage requires documented hypoxemia (SpO2 ≤88% at rest or during exercise)
• Pulmonary rehab: 20 sessions covered (10 more with documentation) for post-CABG, COPD, heart failure

Medicaid

• Medicaid COPD management coverage varies — many plans cover office spirometry for diagnosis
• Prior auth required for ILD and PAH specialty medications under most Medicaid plans
• Home oxygen coverage under state Medicaid may differ from Medicare criteria
• Pediatric asthma management covered under EPSDT — document spirometry and action plan

Commercial Payers

• Lung cancer CT screening coverage follows USPSTF guidelines — verify plan adoption
• ILD biologics (nintedanib, pirfenidone) require prior auth with HRCT and PFT documentation
• PAH treatment prior auth: 6-minute walk test, echocardiography, and right heart cath results required
• Spirometry reimbursement: some commercial plans bundle into E/M — verify with payer

Inpatient Pulmonary Critical Care

• Critical care codes (99291, 99292) are time-based and require 30+ min of physician time
• Ventilator management codes (94002/94003) are separately billable from critical care E/M
• Pulmonary/critical care intensivist rounding billed daily — document separately from subspecialty consults
• ICU daily progress notes must support complexity level billed and not be copy-pasted without updates
