CMS Updates Coverage Policy for Urinary Drainage Bags Under NCD 248
The Centers for Medicare & Medicaid Services (CMS) has modified National Coverage Determination (NCD) 248, which governs coverage of urinary drainage bags under Medicare. The key policy clarification: CMS has determined there is insufficient evidence to support medical necessity for single-use drainage systems over multi-use systems—and will now hold both to the same coverage parameters. If your practice or DME supplier bills for urinary drainage bags, this update has direct implications for how you document and submit claims.

What CMS NCD 248 Covers: Urinary Drainage Bags as Prosthetic Devices
Under NCD 248, CMS covers urinary drainage bags under the Prosthetic Devices benefit category. The coverage rationale is straightforward: these devices replace bladder function in cases of permanent urinary incontinence. That classification as a prosthetic device—not a supply or disposable item—is important for benefit category assignment when submitting claims.
Both bedside drainage bags and leg drainage bags fall within the policy's scope. The policy recognizes two distinct system types:
- Multi-use drainage bags — drainable, designed for repeated use, and include a backflow prevention system
- Single-use drainage bags — non-drainable, include a backflow prevention system, but are intended for one-time use
Both types are addressed under NCD 248, and as of the March 12, 2026, modification, both are evaluated under identical coverage criteria.
The Core Policy Change: Single-Use vs. Multi-Use Systems
This is the operative change billing and RCM teams need to understand. Prior to this modification, there was ambiguity in how single-use drainage systems were evaluated relative to multi-use systems. The updated NCD 248 removes that ambiguity with a direct statement from CMS: there is insufficient evidence to support the medical necessity of a single-use system over a multi-use bag.
What this means in practice: a single-use drainage system will not receive preferential coverage treatment simply because it is single-use. Claims for single-use bags must meet the same coverage parameters as claims for multi-use bags—no exceptions based on product type alone.
This is a meaningful clarification for any practice or supplier that has been billing single-use systems under the assumption that their design characteristics automatically justified a different coverage category or higher reimbursement.
Medical Necessity Criteria Under CMS NCD 248
The coverage criteria under this policy are defined by a single, specific clinical threshold. CMS will cover urinary collection and retention systems when the device replaces bladder function in the case of permanent urinary incontinence.
Breaking that down, your documentation needs to support two elements:
| # | Covered Indication |
|---|---|
| 1 | Permanence — Temporary or transient incontinence does not meet the threshold. The incontinence must be documented as a permanent condition. |
| 2 | Bladder function replacement — The device must functionally substitute for the patient's lost bladder control, not simply manage symptoms in a patient who retains some bladder function. |
Documentation shortfalls on either point create claim vulnerability. Physicians ordering these devices should ensure their clinical notes explicitly address permanence and the functional role of the drainage system—not just a diagnosis code alone.
| 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 |
Affected Codes
This policy does not list specific HCPCS or CPT codes. Per the CMS policy document, applicable claims processing instructions are cross-referenced separately, and no specific procedure or product codes are enumerated within NCD 248 itself. Billers should consult the CMS Claims Processing Instructions cross-reference and their MAC's local guidance for the applicable HCPCS Level II codes associated with urinary drainage bags.
If your MAC has issued a related Local Coverage Determination (LCD) or billing article, that document will contain the specific HCPCS codes relevant to your jurisdiction.
What Your Billing Team Should Do
| # | Action Item |
|---|---|
| 1 | Audit open and recent claims for single-use drainage bags before March 12, 2026. Pull claims submitted under any single-use urinary drainage bag product codes in the last 12 months. Verify that the supporting documentation would satisfy the multi-use coverage standard—specifically that the record establishes permanent urinary incontinence with the device functioning as a bladder replacement. |
| 2 | Update internal coverage determination checklists immediately. If your team has a separate checklist or criteria set for single-use versus multi-use drainage systems, collapse those into a single standard. Both product types now require identical medical necessity documentation. Remove any language suggesting single-use bags receive a different evidentiary standard. |
| 3 | Communicate the change to ordering physicians and clinical staff. The documentation burden to support coverage hasn't changed in kind—but it has been clarified and standardized. Ordering clinicians should know that "permanent urinary incontinence" must be explicitly stated in their notes, not implied by diagnosis alone. A brief provider advisory or order requisite update can prevent downstream denials. |
| 4 | Confirm HCPCS code assignment with your MAC. Since NCD 248 does not enumerate specific product codes, contact your Medicare Administrative Contractor or check your MAC's website for any associated billing articles that specify the correct HCPCS Level II codes for single-use and multi-use drainage bags in your jurisdiction. Mismatched codes remain a leading cause of preventable denials in DME billing. |
| 5 | Flag this policy in your denial management workflow. If you begin to see denials citing "no evidence of medical necessity for single-use system," that's the policy operating as written. The path to appeal—or, better, prevention—runs through stronger upfront documentation of permanent incontinence. |
