Summary: The Centers for Medicare & Medicaid Services modified its coverage policy for postural drainage procedures and pulmonary exercises, effective May 15, 2026. Here's what billing teams need to do before that date.
CMS postural drainage and pulmonary exercise billing has always required tight documentation — and this modification signals that CMS is tightening the screws further. The policy does not carry a numbered policy code in CMS's standard NCD or LCD framework based on available data, but it affects respiratory therapy billing across pulmonology, physical therapy, and home health settings. If your practice or facility bills for chest physiotherapy, bronchial drainage, or therapeutic pulmonary exercises, this change is on your radar now.

CMS Postural Drainage and Pulmonary Exercise Coverage Criteria and Medical Necessity Requirements 2026
The CMS postural drainage procedures and pulmonary exercises coverage policy governs when Medicare will pay for services designed to mobilize secretions and improve ventilatory function. These services appear across inpatient, outpatient, and home health billing — which means the financial exposure from this modification is wider than it might look at first glance.
Medical necessity is the core question with this policy. CMS historically requires documented evidence that a patient has a condition causing excess bronchial secretions — think cystic fibrosis, bronchiectasis, chronic bronchitis, or a post-surgical pulmonary complication — before coverage kicks in. A general diagnosis of COPD alone has not consistently been enough. Your documentation needs to show the clinical rationale for why postural drainage or a structured pulmonary exercise program is the appropriate intervention for that specific patient.
Postural drainage involves positioning a patient so gravity helps drain mucus from specific lung segments. Pulmonary exercises — sometimes called breathing exercises or respiratory muscle training — target ventilatory capacity and secretion clearance. These are distinct services, and CMS has historically been particular about whether the documentation supports each specific service type billed. Don't assume that billing one justifies the other.
Prior authorization is not universally required under traditional Medicare fee-for-service for these services. However, Medicare Advantage plans — which follow their own prior authorization rules — are a different matter entirely. If your patient mix includes Medicare Advantage enrollees, check each plan's prior authorization requirements separately. Some plans have been aggressive about requiring prior auth for ongoing respiratory therapy services.
The real issue with a policy modification like this is what changed. Because the specific policy detail is not publicly available in the current document, you need to pull the full text directly from CMS or your Medicare Administrative Contractor before May 15, 2026. Talk to your compliance officer now — don't wait for a claim denial to tell you what shifted.
CMS Postural Drainage and Pulmonary Exercise Exclusions and Non-Covered Indications
CMS has consistently excluded certain uses of postural drainage and pulmonary exercise services from coverage. Understanding these boundaries protects your reimbursement and keeps your denial rate down.
Prophylactic use — meaning services provided to patients without documented pulmonary pathology or secretion-clearance dysfunction — is generally not covered. If a patient doesn't have a clinical reason to need bronchial drainage, the claim won't survive scrutiny.
Services provided solely for general conditioning or fitness improvement fall outside the coverage policy. Pulmonary rehabilitation is a different benefit category with its own billing guidelines. Mixing these up at the charge capture level is a common source of claim denial.
Maintenance therapy — once a patient has plateaued and no further clinical improvement is expected — has historically been a gray zone. CMS's skilled care standard applies here: if a skilled professional isn't necessary to perform or supervise the service, Medicare generally won't pay. For home health settings especially, this distinction drives a lot of audit activity.
Coverage Indications at a Glance
Because the specific policy document does not list detailed indication-level criteria in the currently available data, the table below reflects established CMS coverage principles for postural drainage and pulmonary exercise services. Verify against the full policy text before May 15, 2026.
| Indication | Coverage Status | Notes |
|---|---|---|
| Cystic fibrosis with documented secretion retention | Covered | Strong medical necessity documentation required |
| Bronchiectasis with active secretion-clearance dysfunction | Covered | Physician order and clinical documentation required |
| Chronic bronchitis with excess secretion production | Covered (when criteria met) | Must document secretion burden and clinical necessity |
| Post-surgical pulmonary complications requiring drainage | Covered | Acute clinical indication must be documented |
| COPD without documented secretion-clearance problem | Not Covered | Diagnosis alone is insufficient for coverage |
| General conditioning or fitness-based pulmonary exercises | Not Covered | Does not meet medical necessity standards |
| Prophylactic use in patients without pulmonary pathology | Not Covered | No clinical indication present |
| Maintenance therapy after patient plateau | Not Covered (generally) | Skilled care standard applies; assess on a case-by-case basis |
| Medicare Advantage enrollees | Coverage Varies | Check individual plan prior authorization requirements |
CMS Postural Drainage and Pulmonary Exercise Billing Guidelines and Action Items 2026
This modification is live on May 15, 2026. That gives you a defined window to get your house in order. Here's what to do.
| # | Action Item |
|---|---|
| 1 | Pull the full policy text from CMS or your MAC before May 15, 2026. The available summary data for this modification is limited. Your MAC's website is the most reliable source for the complete coverage policy language. Don't rely on third-party summaries — including this one — as a substitute for the primary source. |
| 2 | Audit your documentation templates for postural drainage and pulmonary exercise orders. Your physician orders and therapy notes need to clearly establish the clinical basis for each service. Document the specific condition, the secretion-clearance or ventilatory impairment, and why this service is medically necessary for this patient. Generic "COPD — respiratory therapy ordered" language will not hold up. |
| 3 | Review your charge capture for any codes tied to postural drainage and bronchial hygiene services. The policy does not list specific CPT or HCPCS codes in the currently available data — which means your coding team needs to cross-reference your current charge master against the full CMS policy text once it's available. Capture this as a task before May 15, 2026. |
| 4 | Check your Medicare Advantage contracts separately. MA plans are not bound by the same coverage policy rules as traditional Medicare. Some have more restrictive prior authorization requirements for ongoing pulmonary therapy. Identify which of your payers follow CMS fee-for-service rules and which have their own criteria. Your billing guidelines for MA plans may need separate documentation standards. |
| 5 | Train your therapy and clinical staff on the skilled care distinction. If your facility bills for postural drainage in a home health or skilled nursing context, make sure your team understands the difference between skilled and maintenance services. Claims for services that don't require a skilled professional — or that continue after a patient plateaus — are a high-frequency audit target. |
| 6 | Flag this for your compliance officer now. Because the specific changes in this modification are not fully detailed in the available policy data, your compliance officer needs to review the full document and assess how it applies to your specific service mix. If you're billing these services in volume, that review needs to happen before May 15, 2026 — not after your first denial wave. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Postural Drainage Procedures and Pulmonary Exercises
The available policy data for this CMS modification does not list specific CPT, HCPCS, or ICD-10 codes. Do not rely on assumed or commonly referenced codes until you have confirmed the complete policy text from CMS or your Medicare Administrative Contractor.
Postural drainage and pulmonary exercise billing commonly involves codes from the physical medicine and respiratory therapy sections of CPT — but which codes apply under this specific modified coverage policy requires direct verification against the source document. Using the wrong codes, or codes that this policy does not address, creates claim denial risk and audit exposure.
Pull the full policy from your MAC's local coverage determination (LCD) database or from CMS directly. Once you have the specific codes, update your charge master to flag them for documentation review before submission.
If your MAC has issued an LCD that references this policy area, that LCD is your primary billing reference. LCDs from your regional Medicare Administrative Contractor often contain more specific coding and documentation guidance than the national policy. Search your MAC's website for any postural drainage or pulmonary exercise LCDs that are active or pending as of the May 15, 2026 effective date.
No Codes Confirmed From Policy Data
| Code Type | Status |
|---|---|
| CPT | Not listed in available policy data — verify with CMS/MAC |
| HCPCS | Not listed in available policy data — verify with CMS/MAC |
| ICD-10-CM | Not listed in available policy data — verify with CMS/MAC |
This is a gap worth flagging explicitly. A policy modification that doesn't come with a clear code list in available documentation creates real ambiguity for billing teams. That ambiguity is your risk until you get the full text.
