HCPCS code E0246 – Transfer tub rail attachment

Key takeaways

HCPCS code E0246 describes a transfer tub rail that attaches to the bathtub itself, not a wall rail, a floor-base rail or a tub bench.

Original Medicare does not cover E0246, so it has no fee schedule allowance, no DME MAC LCD and no KX modifier.

Medicare lines for E0246 carry GY, or GA when the patient signed an ABN, and the supplier may bill the patient.

Medicare Advantage, Medicaid and commercial plans may cover E0246 under their own criteria, so verify benefits and prior authorization first.

Code the rail by its mounting point, which is E0246 on the tub, E0241 on the wall and E0242 on a floor base.

HCPCS code E0246 covers a rail that clamps to the tub

HCPCS code E0246 is the Level II code that the Centers for Medicare & Medicaid Services (CMS) assigns to a transfer tub rail attachment. The rail fixes to the side of a standard bathtub and gives the patient a firm handhold while stepping in or out. It needs no wall installation, which sets it apart from a wall rail, a floor-base rail or a tub bench.

E0246 sits in the E-section of the HCPCS Level II code set, E0100 to E9999, which covers durable medical equipment. Within it, E0246 belongs to the bath and toilet aids range, E0240 to E0249. Its neighbors include wall and floor rails, toilet rails, raised toilet seats and tub benches. CMS publishes HCPCS Level II updates every quarter.

Because Part B does not price E0246, there is no national or local Medicare rate to look up. The supplier sets its own charge, and the patient or another plan pays it.

E0246 means tub-mounted, not wall or floor rails

E0246 describes one device: a rail that attaches to the bathtub itself and serves as a transfer aid. Code the device by where it mounts, because each neighboring code describes a different mounting point or a different item.

• Covered by E0246: a rail that clamps onto the side of the tub so a patient can lower into it or rise out of it.
• Use E0241 instead: a rail fixed to the bathroom wall beside the tub. The descriptor is “Bath tub wall rail, each.”
• Use E0242 instead: a bathtub rail that stands on a floor base.
• Use E0243 instead: a rail beside the toilet. The descriptor is “Toilet rail, each.”
• Use E0244 instead: a raised toilet seat.
• Use E0245 instead: a tub stool or bench placed in the tub.
• Use E0247 instead: a transfer bench for the tub or toilet.
• Wall grab bars: no specific HCPCS code exists. Bill E1399 where a plan covers them, or treat them as noncovered.

Two mix-ups come up often in bath safety coding. E0156 is a seat attachment for a walker, so it never describes a grab bar. E0241 is a wall rail, so it never describes a rail mounted on the tub.

Is E0246 covered by Medicare?

No, Original Medicare does not cover E0246. The HCPCS file gives it pricing indicator 00, which means Part B does not price it separately. There is no DMEPOS fee schedule allowance for it either.

None of the four DME MAC jurisdictions has an LCD for E0246. Noridian runs Jurisdictions A and D, and CGS runs B and C. With no LCD, there is no covered-diagnosis list and no KX requirement.

The HCPCS file gives E0246 coverage code C (carrier judgment) and no DME MAC LCD sets criteria for it. That puts E0246 in the same position as E0244 and E0172, which policy article A52461 lists as noncovered. E0241, which carries HCPCS coverage code M, sits there too.

One detail differs. Code C means carrier judgment, while code M means noncovered by Medicare. So describe E0246 as not covered by Original Medicare, rather than statutorily excluded.

In practice, Medicare denies the line and the supplier may bill the patient. Payment comes only from a Medicare Advantage, Medicaid or commercial plan that chooses to cover the rail.

The records that back up an E0246 claim

With no Medicare coverage criteria to meet, E0246 documentation does two jobs. It supports a claim to a plan that covers the rail, and it protects the supplier when the patient pays.

1. Written order. A signed, dated order from the treating practitioner that names the patient, the device and the prescriber’s NPI. Plans that cover the rail usually ask for one.
2. Clinical notes. Notes that describe the transfer difficulty, such as unsteadiness, weakness or a recent hip replacement. Medicaid and commercial plans weigh these against their own criteria.
3. Benefit check record. The date, the plan, the portal or call reference and the prior authorization outcome.
4. ABN, where you use one. A signed Advance Beneficiary Notice of Noncoverage (ABN) for a Medicare patient, showing the item, the expected cost and the patient’s choice.
5. Patient cost agreement. The patient’s written agreement to pay for the rail when no plan covers it.
6. Proof of delivery. A signed delivery receipt showing the date, the item and the recipient’s signature.

Keep these records in line with your medical billing compliance policy. Medicare-enrolled DMEPOS suppliers also keep their accreditation current and retain records for seven years.

Diagnoses that show why the patient needs a rail

No LCD lists diagnoses for E0246, so no code below guarantees payment. These are examples a practitioner may document to show why a patient needs help with tub transfers.

G20 on its own has not been billable since FY2024. Code Parkinson’s disease to G20.A1, G20.B1 or the G20 subcode that matches the documentation.

E0246 modifiers: GY or GA, never KX

The modifiers on an E0246 line depend on which payer you bill. On an Original Medicare claim, the line goes out as a noncovered item and never carries KX. The flow below shows where each payer route ends.

A line billed with KX attests to coverage criteria that do not exist for E0246. If past claims carry KX on E0246, review them with your compliance lead and bill future lines with GY or GA.

The mounting point separates E0246 from similar codes

The bath and toilet aids range is small, but its codes are easy to mismatch. Use this table to pick the right code before you bill.

E0246 and E0241 are easy to confuse because both are bathtub rails. An E0246 rail attaches to the tub itself, while an E0241 rail is fixed to the bathroom wall.

Prior authorization for E0246 comes from the paying plan

Original Medicare has no prior authorization for E0246, because it does not cover the item at all. A Medicare Advantage, Medicaid or commercial plan that covers the rail may require prior authorization before delivery.

• Medicare Advantage: some plans offer bath safety items as a supplemental benefit. Check the plan’s evidence of coverage and its authorization rules.
• Medicaid: coverage depends on the state and often on the managed care plan or waiver program. Check the state’s DME provider manual.
• Commercial plans: for Aetna members, check Aetna’s current DME clinical policy bulletin. For other insurers, check the equivalent DME policy.

Record each check with the date and reference number, and get approval before the rail ships.

Seven mistakes that get E0246 claims denied

Studying the patterns behind claim denials helps suppliers fix the process as well as the claim. These are the errors to check for on E0246.

How an E0246 claim moves, step by step

Billing E0246 starts with the payer, not the code. These seven steps cover Original Medicare and the plans that may pay. For the basics behind each step, see what medical billing involves.

1. Confirm the device and the code. Check that the rail attaches to the tub itself. A wall rail is E0241, and a floor-base rail is E0242.
2. Get a written order. Obtain a signed, dated order from the treating practitioner before delivery.
3. Identify the payer. Original Medicare does not cover E0246. Medicare Advantage, Medicaid and commercial plans each set their own rules.
4. Verify benefits and prior authorization. For a plan that may cover the rail, confirm the benefit and request approval. Record the date and the reference number.
5. Agree the cost with the patient. Tell an Original Medicare patient that Medicare will not pay, and give the cost in writing. Have the patient sign an ABN where you use one.
6. Deliver and document. Collect a signed delivery receipt with the date and the item delivered.
7. Submit the claim. Bill Original Medicare on the CMS-1500 or 837P with GY, or GA when a signed ABN is on file. Bill a covering plan with its own modifiers and authorization number, then invoice the patient for any balance.

A clean claim for E0246 matches the code to the device and the modifier to the payer. Get those two right, and the Medicare denial arrives exactly as the patient was told it would.

A worked example: A Medicare patient after hip surgery

Take a Medicare patient going home after a hip replacement. The surgeon orders a rail that clamps to the tub, so E0246 applies. Before delivery, the supplier explains that Medicare won’t pay and gives the price in writing.

The patient signs an ABN and the rail ships with a signed delivery receipt. The claim goes out with GA, Medicare denies the line, and the patient pays the agreed price. Nobody is surprised by the bill.

Before you submit: A quick checklist

• The rail clamps to the tub, not the wall or a floor base.
• A signed, dated order from the treating practitioner is on file.
• The modifier matches the payer, so GY or GA for Original Medicare and never KX.
• A Medicare patient has a signed ABN or written cost agreement.
• A covering plan’s authorization number is on the claim.
• The delivery receipt names a transfer tub rail, not a grab bar or floor rail.

How Pabau keeps E0246 claims and patient balances connected

A practice that supplies bath safety items juggles payer checks, signed notices and patient balances. When those sit in separate tools, a missing ABN or an unpaid balance surfaces weeks later.

Pabau, the practice management platform we build, includes claims management for practices, so the team can submit and track insurance claims from the patient record. Signed forms, clinical notes and invoices sit in the same record, so the team can see what was agreed and what is still owed.

That keeps the order, the claim and the patient’s payment connected, so fewer balances slip through.

Submit and track insurance claims in one place

Pabau helps practices submit and track insurance claims, keep signed forms with the patient record and invoice patients for items their plan does not cover.

Conclusion

E0246 rarely goes wrong on the code itself. It goes wrong when the line carries KX, misses GY or GA, or reaches the patient as a surprise bill. Get the mounting point and the modifier right, and the Medicare denial becomes a routine step.

For patients with Medicare Advantage, Medicaid or commercial cover, the benefit check decides who pays. Run that check before the rail ships, so the patient knows the cost up front.
