HCPCS code A4314 – Insertion tray with drainage bag and catheter

Key takeaways

HCPCS code A4314 is the complete latex Foley kit: an insertion tray, a drainage bag and a two-way coated latex catheter.

The catheter decides the code, so an all-silicone kit is A4315 and a three-way irrigation kit is A4316.

Medicare covers A4314 under LCD L33803 when urinary retention or incontinence is permanent, meaning long and indefinite in duration.

One tray is covered per catheter insertion, and the usual maximum is one A4314 per month.

KX is appended when the LCD coverage criteria are met and documented, while GA, GY or GZ apply when they are not.

HCPCS code A4314 covers the complete coated latex Foley kit

HCPCS code A4314 is the Level II code for a Foley catheter insertion tray that ships with a drainage bag and an indwelling catheter. The catheter is two-way latex with a coating of Teflon, silicone, silicone elastomer or a hydrophilic finish.

All three parts ship together and bill as one line. The code sits in the A range of the HCPCS Level II codes, alongside the other urological supplies that DME suppliers bill to Medicare.

CMS maintains the HCPCS code set and its descriptors. The table below sums up the attributes that matter when you code and bill A4314.

The catheter inside the kit decides the code

Seven tray codes look almost the same on a packing slip. Two questions separate them: is a drainage bag in the kit, and which catheter came with it?

A4314, A4315 and A4316 all hold a tray, a bag and an indwelling Foley. Only the catheter differs. A4314 carries the two-way coated latex catheter, A4315 the two-way all-silicone one, and A4316 the three-way catheter for continuous irrigation.

Take the bag away and you move to the tray codes without one. A4311 holds a coated latex Foley, A4312 an all-silicone one, and A4313 a three-way one. A kit with no catheter at all is A4310 without a bag, or A4354 with one.

The grid below maps every combination, so you can match the shipped kit at a glance.

The three complete kits differ only in the catheter, and each one has its own coverage condition.

The practical rule is simple. Read the catheter on the packing slip before you pick the code. A silicone or three-way kit coded as A4314 misstates what shipped, and an audit will spot it.

Medicare covers A4314 when the condition is permanent

Medicare Part B covers A4314 under the prosthetic device benefit, following LCD L33803 (Urological Supplies). The patient needs permanent urinary retention or permanent urinary incontinence.

Permanent doesn’t mean the condition can never improve. The test is met when the medical record, including the treating practitioner’s judgment, shows it is long and indefinite in duration.

Before you code, confirm three coverage points:

• Permanence: the record describes retention or incontinence of long and indefinite duration, not a short post-operative problem.
• Purpose: the catheter drains urine. Treating a chronic urinary tract infection without permanent retention or incontinence isn’t covered.
• Kit type: an all-silicone or three-way kit needs its own documented reason, such as latex sensitivity or continuous irrigation.

When the condition is temporary, the supplies can’t be billed to the DME MAC. They count as incident to the practitioner’s service, and the practitioner’s payment covers them.

Quantity rules come next. Medicare covers one insertion tray per catheter insertion, and the usual maximum for A4314 is one per month. A second change in the same month needs a documented reason, such as:

• The patient accidentally pulls the catheter out.
• The catheter malfunctions, for example a balloon that won’t stay inflated.
• Encrustation, a mucous plug or a blood clot blocks the catheter.
• Recurrent blockage or infection is prevented by changing it more than once a month.

Only an enrolled DMEPOS supplier bills A4314

A Medicare-enrolled DMEPOS supplier bills A4314 to the DME MAC for its region. Noridian handles Jurisdictions A and D, and CGS handles Jurisdictions B and C.

Setting matters as much as enrollment. During an inpatient stay or a covered Part A facility stay, the kit is bundled into the facility payment. A DME supplier can’t bill it separately to Part B.

Three conditions apply before a supplier submits a claim:

1. The supplier holds active DMEPOS enrollment, with its National Provider Identifier (NPI) linked to that enrollment.
2. A standard written order (SWO) from the treating practitioner reaches the supplier before the claim is submitted.
3. The patient is at home or in a home-equivalent setting at delivery, and the claim uses that place of service, not office POS 11.

How an A4314 claim moves from order to payment

Most A4314 claims follow the same path. Here is the walkthrough, one step at a time.

1. Order: the treating practitioner sends an SWO naming the kit and quantity, signed and dated.
2. Record: the medical record shows permanent retention or incontinence, plus the reason for any special catheter.
3. Delivery: the kit ships to the patient’s home, and the supplier keeps signed proof of delivery.
4. Coding: the supplier matches the catheter on the packing slip to A4314, A4315 or A4316.
5. Modifier: the claim line carries KX, GA, GY or GZ. Lines without one are rejected as missing information.
6. Submission: the claim goes to the DME MAC and is priced against the DMEPOS fee schedule.
7. Payment: Medicare pays 80% of the allowed amount after the Part B deductible, and the patient owes 20%.

Refills run on their own clock. The supplier contacts the patient no sooner than 14 days before the current supply runs out. The refill then ships no sooner than 10 days before that date.

A worked example: one patient, one month of supplies

Picture a patient with neurogenic bladder after a spinal cord injury. The urologist documents permanent retention and orders a coated latex Foley.

On day 1, the supplier ships one A4314 kit and a spare bedside bag, A4357. Medicare counts that as two drainage bags, which is the usual monthly maximum.

On day 18, the patient pulls the catheter out. The supplier ships a second A4314, and the record notes the accidental removal.

That second kit goes past the usual maximum, so the documentation has to explain it. Without that note, the extra line is denied as not reasonable and necessary.

Documentation that holds up under A4314 review

LCD L33803 and Policy Article A52521 set out what a supplier keeps on file. A complete file is your best protection during post-payment review.

1. Standard written order: the patient’s name or Medicare ID, order date, item, quantity, and the practitioner’s name or NPI and signature.
2. Medical record: notes showing the condition is permanent, plus the reason for any silicone or three-way catheter.
3. Proof of delivery: a signed record with the date, item description and quantity, kept for seven years.
4. Usage tracking: the trays and bags shipped each month, with the reason for any extra change.
5. Enrollment: active DMEPOS enrollment on the date of delivery.

Your DME MAC can ask for more during an audit, so check its current guidance before you submit. Filing records by claim, rather than by patient date, makes those requests faster to answer.

Run this checklist before you submit

A couple of minutes with this list catches most A4314 problems before the MAC does.

• The catheter on the packing slip is two-way, coated latex.
• A drainage bag shipped in the kit. Without one, the code is A4311.
• No kit component is billed as an extra line, such as A4338, A4354 or A4357 for the same kit.
• The SWO reached you before the claim was submitted.
• The medical record documents permanence.
• This is the only routine A4314 this month, or the extra change is explained.
• The claim line carries KX, GA, GY or GZ.
• The place of service is the patient’s home, not POS 11.

Where to find the A4314 fee for 2026

Medicare prices A4314 from the DMEPOS fee schedule. CMS publishes it each January and updates it quarterly, and the amounts differ by state.

Check the current amount for your state on the CMS DMEPOS fee schedule before you quote a patient or post a payment. Medicare pays 80% of the allowed amount after the Part B deductible. The patient, or a Medigap plan, covers the other 20%.

Six denials that keep hitting A4314 claims

A4314 denials cluster around six causes, and each one is preventable at order intake. Good denial management starts there, long before a remittance advice arrives.

Fix all six and you’re most of the way to a clean claim on the first pass.

KX, GA, GY or GZ: Picking the right A4314 modifier

First, prior authorization. A4314 isn’t on the CMS required prior authorization list for DMEPOS. Medicare Advantage plans can set their own rules, so check the plan before you ship.

The modifier is where most A4314 lines go wrong. Here are the four questions billers ask most.

When does KX go on the line?

KX is appended when the LCD coverage criteria are met and documented. That includes the permanence test and any extra need for a special catheter.

When do you use GA or GZ?

Use one of them when you expect a medical necessity denial. GA means a valid Advance Beneficiary Notice (ABN) is on file. GZ means it isn’t.

When does GY apply?

GY tells Medicare the item fails the benefit itself, for example when the condition isn’t permanent.

What happens without an ABN?

If you expect a denial and ship without a valid ABN, the supplier carries the cost, not the patient. Issue the ABN before delivery, while the patient can still decide.

Diagnosis codes that document permanent retention

Policy Article A52521 doesn’t publish a diagnosis list for A4314. Its only ICD-10-CM list covers A4336, a urethral insert. Coverage for A4314 rests on documented permanence instead.

Even so, the claim needs a specific diagnosis that explains the retention or incontinence. These codes often appear on indwelling catheter claims.

Specificity still matters. Coding R33.9 when the notes name a cause weakens the file on review, so use the most specific code the record supports.

Related urological supply codes to know

A4314 sits in a family of A codes. When the shipped supplies differ from the full kit, one of these usually fits.

How Pabau keeps A4314 claims and records together

If your practice is enrolled as a DMEPOS supplier, A4314 paperwork tends to scatter. The SWO sits in email, the delivery slip in a folder, and claim status in a separate portal.

Pabau, the all-in-one practice management system we build, keeps orders, treatment notes and invoices on the patient record. Its simpler claims management tools pre-fill the claim from that record and check required fields before you send it. In the US, claims go through Claim.MD, so you can track claim status and remittances in one place.

The coding call stays with your team. Pabau holds the documentation and claim status side by side, so a MAC request is quicker to answer.

Conclusion

A4314 rewards suppliers who code from the packing slip, not from habit. Check the catheter, confirm a bag shipped, and bill the kit as one line.

The bigger risk sits in the file. Get permanence documented and the SWO in hand before you submit, and most denials never happen. Your team then spends less time on appeals and more time on patients.
