Medicare Part B Urological Supply Billing for Skilled Nursing Facilities

Every skilled nursing facility completes a Minimum Data Set for each resident, and Section H covers bladder and bowel. If a resident uses an indwelling catheter, that fact is documented, signed off, and sitting in your clinical record already.

It is also, in most buildings, funding a monthly Part B claim that goes to an external supplier. Here is what Medicare Part B covers for urological supplies, how the catheter documentation your team already produces connects to the billing, and what changes when the facility submits those claims under its own NPI.

Urological Supplies vs. Urostomy Supplies: One Line Worth Drawing

If you have read our breakdown of Medicare Part B ostomy supply billing, you know that urostomy residents, those with a surgically created urinary diversion and an external stoma pouch, generate Part B claims in the A5071–A5073 ostomy pouch range.

Urological supplies are a distinct category. This article covers catheter-based urinary management: indwelling catheters, intermittent catheters, external catheters, drainage bags, and irrigation supplies. Those use a separate HCPCS range and a separate coverage policy, and they serve residents who manage bladder function through a catheter rather than a stoma. Both categories are billable under the facility's NPI, and your billing should treat them as two categories, not one.

What Medicare Part B Covers for Urological Supplies

Medicare Part B covers urological supplies under the prosthetic device benefit at 42 U.S.C. § 1395x(s)(8) for residents who are not in a covered Part A stay. The coverage rules live in the DME MAC coverage policy for urological supplies; the SNF billing instructions are in the Medicare Claims Processing Manual (CMS Pub. 100-04, Ch. 7).

Four supply types show up often enough in skilled nursing to matter. Indwelling (Foley) catheters are covered for residents who require continuous bladder drainage: A4338 is the 2-way latex catheter with coating, A4344 the 2-way all-silicone catheter, A4340 a specialty type such as a coude, and A4346 the 3-way catheter for continuous irrigation. Medicare covers one catheter per month for routine maintenance, with more frequent changes payable when the record documents why, such as accidental removal, malfunction, obstruction, or recurrent obstruction or infection a scheduled change prevents. Specialty, all-silicone, coude, and 3-way catheters each need a documented clinical reason.

Intermittent catheters serve residents with permanent retention or incontinence from neurogenic bladder, spinal cord injury, or a similar condition preventing normal voiding, where the resident or a caregiver can perform the catheterization. A4351 is the straight-tip catheter and A4352 the coude tip; A4353 is the intermittent catheter with insertion supplies, the sterile kit. Since January 1, 2026, hydrophilic-coated catheters bill under A4295, A4296, and A4297. External (condom) catheters bill A4349, and drainage bags bill A4357 (bedside) and A4358 (vinyl leg bag), with insertion trays and irrigation supplies carrying their own codes.

One criterion is specific to your setting: the sterile intermittent catheter kit (A4353, or A4297 for the hydrophilic kit) is covered when the beneficiary resides in a nursing facility. The kit code cannot be billed when the components are supplied separately. For a resident catheterized four times a day, that is roughly 120 catheterizations in a 30-day month, well inside the 200-per-month usual maximum, and it recurs every month the program continues.

What the Claim Requires

Billing urological supplies under Part B requires a signed order from the treating practitioner, who may be a physician, PA, NP, or CNS, plus documentation of medical necessity. Since 2020 the standard written order needs the resident's name or MBI, the order date, a description of the item, the quantity, and the practitioner's name or NPI and signature. Frequency and diagnosis are not required order elements; the medical record is what has to establish the permanent condition and support the quantity.

Medicare does not ask you to justify an indwelling catheter over an intermittent program. What it asks for is the permanent retention or incontinence behind the catheter, a documented reason for any specialty, all-silicone, coude, or 3-way catheter, and a documented reason for any change more often than monthly or any quantity above a usual maximum.

That documentation is already in your building. It is in the nursing notes, the care plan, and the physician orders, and it is on the MDS. Section H, Bladder and Bowel, records indwelling catheter use (including suprapubic and nephrostomy), external catheter, ostomy, and intermittent catheterization, alongside urinary continence, on the comprehensive and quarterly item sets. If you want the wider documentation picture, see SNF Part B documentation and audit readiness.

How External Suppliers Capture This Revenue

Most SNFs have a catheter supply arrangement with a DME supplier that predates any awareness of the facility-NPI alternative. The supplier delivers the products, submits the claim under its own NPI where the item is separately billable to it, and receives the reimbursement. The facility gets the supplies but neither the claims revenue nor the claim data behind it.

For residents on intermittent catheter programs the monthly volume is substantial, and it runs every month for as long as the condition requires the program. An external supplier does not have direct access to your clinical record, so it works from whatever the order said at setup, which may not reflect a later change in catheterization frequency or care plan. Facility-side billing with read-only access to the chart catches those discrepancies before a claim goes out. If you have never examined the arrangement claim by claim, start with the five-step supply vendor audit.

What the Facility-NPI Model Changes

When a SNF purchases urological supplies and bills under its own NPI, the Medicare reimbursement flows to the facility. The catheter protocol stays with your clinical team, supply selection stays with the prescribing practitioner, and the documentation workflow stays the same. What changes is the NPI on the claim and the destination of the remittance. The broader comparison is in supplier-billed vs. facility-NPI Part B billing.

The MDS connection is specific to skilled nursing. Hospitals do not complete a Minimum Data Set for their acute inpatients, though swing-bed hospitals do for swing-bed patients. The SNF MDS is a care planning tool, a quality reporting tool, and, connected to a facility-NPI billing workflow, the clinical foundation for a recurring Part B revenue line. Many facilities use two of those three and leave the third disconnected.

The Compliance Case for Billing Under Your Own NPI

CMS lists DMEPOS suppliers as one of its fraud hot spots, and urological supplies are among the items it names as most often targeted. In its most recent improper payment reporting, CMS projected roughly $2.3 billion in improper DMEPOS payments at a 24.1% rate, with urological supplies the highest projected category at about $886 million and a 74.1% improper payment rate.

Those figures cover claims billed by DMEPOS suppliers, and CMS is careful to say that an improper payment rate is not a fraud rate. Most of the urological errors were claims where no documentation was produced at all, many from suppliers already under payment suspension. Behind the number sits the 2023 catheter scheme, in which a small group of suppliers billed Medicare for catheters that were never ordered and never delivered; CMS reports it stopped more than $4.2 billion of those payments before they went out and revoked every one of those suppliers. The remaining catheter errors trace to records that did not support the coverage criteria, missing refill requests, missing orders, and missing proof of delivery.

In a standard supplier arrangement, your documentation supports a claim someone else submitted, and the entity that billed cannot directly produce the records behind it. When the review letter arrives, the supplier comes back to you for the catheter orders and nursing notes, and the clock is already running. When the facility bills under its own NPI, the claim and the records sit with the same entity. That does not change the coverage rules, and CMS does not endorse one billing model over another; what changes is who holds the records the reviewer asks for.

What Burst Does for SNF Urological Billing

Burst reads the urological documentation your clinical team already produces in PointClickCare, identifies the applicable HCPCS codes by catheter type and supply category, verifies claim quantity against the order, the record, and the published usual maximums, and submits the claim under your facility's NPI. Burst is a PointClickCare Marketplace Partner with read-only access, so your staff does not learn a new system. See how the PointClickCare integration works.

Human QA runs on every claim before submission, so catheter type misclassifications, quantity documentation gaps, and medical necessity flags are caught before the claim leaves our system. Burst processed 18,974 claims in 2025 and works with facilities in 16 states.

Your current catheter supplier relationship stays intact, and Burst does not specify products. The contingency model means no setup fee, no monthly minimum, and a month-to-month term. Details are on the Part B supplies reimbursement service page.

Compliance Note

This article is general information, not legal or billing advice. Coverage rules, HCPCS codes, and quantity limits change; the hydrophilic catheter codes above took effect January 1, 2026. Verify each item against current contractor instructions and the applicable Local Coverage Determination, and have your compliance officer or counsel review any change in billing arrangement before implementation.
