Your Catheter Claims Are Still Coded for a Program CMS Retired in January
New HCPCS codes for hydrophilic catheters took effect January 1. Seven months later, claims are still landing under retired numbers, right as federal investigators call urinary catheters the biggest DME fraud story of the year. Here's what your intake team needs to check before the next order ships.
Effective January 1, 2026: CMS retired HCPCS codes A4351, A4352, and A4353 for hydrophilic-coated intermittent catheters and created three replacement codes: A4295, A4296, and A4297. Suppliers still billing hydrophilic catheters under the old numbers are filing claims that no longer match the product on file, in the same category federal investigators just called the center of a $10.6 billion fraud scheme.
A code that quietly stopped existing
On January 1, 2026, CMS split hydrophilic catheters off from the codes they had shared with every other intermittent catheter for years. A4351 and A4352 used to cover straight and coude tip catheters "with or without coating (Teflon, silicone, silicone elastomer, or hydrophilic, etc.)." That "etc." is gone now. The narrative for both codes was rewritten to describe only Teflon, silicone, or silicone elastomer coatings. Hydrophilic-coated catheters got their own codes: A4295 for straight tip, A4296 for coude tip, and A4297 for hydrophilic catheters that ship with insertion supplies.
It sounds like a small edit. It isn't. If a supplier is still billing a hydrophilic catheter under A4351, A4352, or A4353 for a date of service after January 1, that claim describes a product Medicare no longer recognizes under that number. The catheter itself is fine. The code is wrong, and a wrong code doesn't get partial credit at the payer.
"The catheter didn't change. The code did. Medicare doesn't pay claims for good faith effort."
Why this code change is landing harder than most
Most HCPCS code splits are administrative housekeeping that billing teams catch within a claim cycle or two. This one is different because of what else happened in 2025. In June, the Department of Justice announced Operation Gold Rush, a takedown involving more than $10.6 billion in fraudulent Medicare claims, much of it built on urinary catheters. Investigators found the category attractive precisely because a low-dollar catheter claim rarely draws the scrutiny an expensive wheelchair or infusion pump does. That's changing fast. CMS suspended payments to suppliers tied to the scheme and has been tightening vetting and monitoring across the entire urological supplies category ever since.
The federal payment data backs this up. Urological supplies had a 74.1% improper payment rate in the 2025 CERT report, the highest of any DME category, totaling $885.8 million in improper payments. The reason cited in nearly every case was the same: insufficient documentation to support coverage criteria. A claim billed under a retired code, describing a product that no longer matches what CMS has on file, is exactly the kind of claim automated review now flags first.
What changed, before and after
The practical shift is a coding split that removed a piece of shared vocabulary billing teams had relied on for years:
Fixing a wrong code before a claim goes out takes one lookup. Fixing it after a denial means a new claim, sometimes a new standard written order, and a wait behind every other appeal already stacked up in a category regulators are watching closely. For a supplier processing hundreds of resupply orders a month, even a handful of claims still coded the old way adds up fast.
Where the real gaps sit
The code change itself is simple to fix on paper. Finding every place it hasn't been fixed yet is the harder part. Five spots in a typical hydrophilic catheter order carry the most exposure right now.
| Order component | Common gap | What it affects | Risk level |
|---|---|---|---|
| HCPCS code selection | Hydrophilic catheter billed under legacy A4351, A4352, or A4353 instead of A4295, A4296, or A4297 | Every hydrophilic intermittent catheter claim | High |
| Standard Written Order (SWO) | Order written before 2026 names a retired code by number and was never reissued | Recurring and resupply orders written before the code split | High |
| Monthly quantity | Order requests more than 200 catheters a month without notes documenting clinical need | High-frequency self-catheterization patients | Moderate |
| Diagnosis-to-LCD match | Chart doesn't clearly document a qualifying condition like neurogenic bladder or permanent retention | All urological supply claims | Moderate |
| Same-or-similar check | Beneficiary already receiving catheters from another supplier in the same billing period isn't verified before shipping | Resupply and subscription-style orders | Moderate |
What intake should check before every hydrophilic catheter order ships
None of this requires new software or a new process, just a specific list run against every hydrophilic catheter order before it leaves intake.
Pre-submission checklist for hydrophilic catheter orders
This is a timing problem, not a training problem
Talk to any DME billing director about catheter denials and you'll hear a version of the same thing: the coordinators know the rules. What they don't have is the extra two minutes per file to cross-check a formulary sheet that may or may not have been updated since December against a written order that may or may not have been reissued against a diagnosis code that may or may not match the LCD. At 80 or more files a day, that check either happens for every file or it happens for almost none of them.
CMS didn't create this problem by splitting the code. The split just removed the cushion. Under the old shared code, a hydrophilic catheter billed with slightly stale documentation could still process. Under the new codes, layered on top of a fraud crackdown that already has reviewers looking harder at every catheter claim, a mismatch surfaces fast, and it surfaces as a denial with a reason code attached rather than a request for more information.
"A denial caught before submission costs a phone call. A denial that comes back after the fact costs an appeal, and catheter appeals are exactly where reviewers are looking hardest right now."
What to do this week
1. Pull every open hydrophilic catheter order and check the code
Sort by HCPCS code and flag anything still listed as A4351, A4352, or A4353 for a hydrophilic product. This is a spreadsheet exercise, not a system overhaul, and it tells you the size of the problem in an afternoon.
2. Update every reference sheet and order template that still shows the old codes
Formulary sheets, EHR order sets, and printed intake forms often lag a CMS coding update by months. If coordinators are pulling codes from a document dated before December 2025, that document is the source of the denial, not the coordinator.
3. Reissue standard written orders that name the retired code directly
An SWO that lists A4351, A4352, or A4353 by number for a hydrophilic catheter needs a new order dated for 2026. An SWO that uses a general description, such as "hydrophilic catheter," or names a brand or model, doesn't need to be reissued. Know which patients fall into each group before their next resupply ships.
The code split took effect seven months ago. The fraud crackdown that makes it expensive to get wrong isn't slowing down. The question worth answering this week is whether the catheter claims leaving your intake desk are coded for the program that exists now, or the one that ended in December.

We help DME suppliers validate HCPCS codes, standard written orders, and LCD-matched diagnoses at intake, before a claim reaches a payer that's already watching every catheter order closely. If you want to see what that check looks like against your own files, we're glad to walk through it.
