General information, not medical advice or an insurance coverage decision. MedraxDME operates as an out of network supplier. Coverage, supplier enrollment requirements and patient responsibility depend on the plan and an individual review.
Start with the prescribed type and actual use
“Catheters per month” is not one universal number. Intermittent catheters, indwelling catheters, external collection devices and drainage supplies serve different purposes and have different policy rules. Your clinician’s instructions determine the intended use; a monthly insurance table should never be used to change that schedule.
The current Medicare Urological Supplies LCD is L33803, with a revision effective April 1, 2026. It contains code specific quantities and conditions, including newer hydrophilic catheter codes that may be absent from older online summaries. CMS: Urological Supplies, LCD L33803.
Before asking about quantities, identify the exact prescribed product, size, tip style and whether it is supplied as a catheter or a kit. Keep the product reference available for a private conversation. Two items both called “intermittent catheters” may not be coded or packaged in the same way.
What the Medicare table does and does not say
The current LCD lists a usual monthly maximum of 200 for several intermittent catheter codes, including A4295, A4296, A4297, A4351, A4352 and A4353. It also limits the combined sterile kit quantity for A4297 and A4353 to 200. This does not mean that everyone qualifies for every code or should receive every listed quantity. CMS: Urological Supplies, LCD L33803.
The actual request must match the prescribed use and the product supplied. A patient using one type of catheter does not gain a second independent allowance by adding a different code to the request. A supplier should not treat the maximum as a target when the expected use is lower.
Other insurance plans may use different policies. Ask the plan for the rule that applies to your product and date of service. A Medicare number found in an article is not a substitute for a commercial plan or Medicaid benefit determination.
Indwelling and external devices follow different rules
Medicare’s provider guidance distinguishes routine indwelling catheter maintenance from nonroutine changes supported by medical necessity. It also describes separate quantities for external collection devices and associated supplies. These are not interchangeable with the intermittent catheter allowance. CMS: urological supplies documentation.
If a catheter has malfunctioned or a clinical problem requires a change, contact the clinician responsible for your care. Do not wait for a routine refill date to obtain clinical advice, and do not independently alter the treatment plan to match a supply limit.
When discussing a supply request, describe the device accurately. A drainage bag, insertion tray and catheter are separate items even when provided together. Clarify which components the existing order includes and which need separate review, rather than asking for a generic “extra catheter kit.”
Product identification and coding must agree
The Urological Supplies policy article explains how products and kits are classified. It also addresses the underlying prosthetic device benefit and the documentation used to support a claim. A retail package count is not necessarily the same thing as a billing unit. CMS: Urological Supplies Policy Article A52521.
Keep the manufacturer reference, catheter size, length, tip configuration and package description available. If the supplier proposes an alternative, confirm the clinical specifications with the prescribing professional. A similar photograph or matching brand does not prove that the replacement is appropriate.
Hydrophilic coating, a curved tip or a sterile kit should not be added solely because it sounds more advanced. The selected product should match the order and relevant criteria. Ask why a proposed configuration is needed and how it is supported, without attempting to choose the billing code yourself.
Document need without sending private information publicly
The clinician’s record should support the reason for catheter use and the prescribed quantity. If a plan asks for clarification, ask whether it needs the order, the clinical record, a description of an exception or information about a different product type. The supplier should explain the missing item specifically.
CMS’s compliance guidance emphasizes that records must support medical necessity. CMS: urological supplies documentation. That does not mean patients should paste medical histories into an ordinary website form. Use a secure route arranged by the clinical office, insurer or supplier for the necessary information.
For your own organization, keep a nonclinical checklist of dates and next actions. Note who is obtaining the order, who is checking benefits and whether the plan has responded. Keep the actual health records in their appropriate secure location, not in a general email thread.
Plan refills around remaining supplies and confirmed instructions
Before requesting a refill, count the unopened supplies you actually have and check the product references. Distinguish a delivery shortage from a change in use or an early product problem. This helps the supplier ask the right questions without assuming the previous order still matches your needs.
A change in use should be discussed with the treating professional. Do not ration prescribed supplies, reuse a single use item contrary to its instructions, or change catheterization frequency based on an administrative allowance. Clinical safety and the insurance process are related but separate responsibilities.
Ask when the next request can be reviewed and whether the existing order remains current. If you are changing suppliers, coordinate the transition to avoid duplicate shipments or a gap. A callback request is not a confirmed refill, and a plan’s benefits explanation is not a carrier delivery commitment.
Questions that make a quantity review more precise
- What exact catheter or collection device is prescribed?
- Which product reference and package configuration match that order?
- What is the prescribed use and requested monthly quantity?
- Does the plan have a usual maximum, and does a different review apply to an exception?
- Are lubricant, drainage supplies or insertion components included in the relevant kit?
- Is the supplier permitted under the plan?
- Is authorization required before fulfillment?
- When should remaining supplies be reviewed for the next refill?
- Who handles a product defect, delivery shortage or clinical concern?
These questions help separate a quantity issue from a product mismatch. If a decision is unfavorable, ask for the reason and the applicable policy in writing before assuming that all catheter supplies are excluded.
Using MedraxDME for an initial conversation
The urology catalog helps identify products and supplies for discussion. It does not prescribe a catheter type, frequency or monthly allowance. MedraxDME is an insurance only, out of network service, and the team must confirm whether it can support the request under your particular benefits.
Use the insurance callback form for contact details and optional equipment selections. Do not submit member numbers, diagnoses, treatment logs or clinical documents there. The team can explain the appropriate next step and how any required records should be handled.
Before fulfillment, confirm the exact item, quantity, current order, benefits outcome and delivery arrangements. If your plan requires a different supplier, ask it to identify an eligible option. Accurate product and benefits information should come before any expectation of shipment.
Questions and answers
Does the 200 per month figure apply to everyone?
No. It is a usual maximum for specified Medicare intermittent catheter codes, subject to coverage conditions and actual need. It is not a prescribed use schedule.
Can I add two catheter codes to double the allowance?
No. Codes must reflect the actual products and need. The current policy also sets a combined limit for the specified sterile catheter kit codes.
Do private plans always follow Medicare’s quantity table?
No. Ask the plan for its applicable product and quantity policy and confirm any authorization requirements.
