HCPCS code K0044 – Wheelchair footrest upper hanger bracket

Key takeaways

HCPCS code K0044 covers one wheelchair footrest upper hanger bracket, supplied as a replacement part and billed per bracket.

The code never applies to a footrest that ships with a new wheelchair, because that footrest is included in the base code.

Coverage follows the Wheelchair Options/Accessories LCD (L33792) and its policy article (A52504).

Replacement claims carry the RB modifier, plus KX, GA, GZ or GY depending on whether coverage criteria are met.

Most K0044 denials come from billing the wrong footrest part, a missing modifier, or no record of why the old bracket failed.

HCPCS code K0044: Official description and code definition

HCPCS code K0044 describes a footrest, upper hanger bracket, replacement only, each. It is a Level II code in the K-series, which CMS maintains for durable medical equipment billed to the DME Medicare Administrative Contractors (MACs).

The upper hanger bracket is the top part of a footrest hanger, the piece that attaches the footrest to the wheelchair frame. K0044 pays for that bracket alone when it breaks or wears out on a wheelchair the patient already uses.

Getting it right sits inside the wider medical billing cycle, where the code on the claim has to match the part in the box.

The AAPC’s HCPCS Level II code lookup provides a searchable index of K-series codes with descriptor text. PGM Billing’s free HCPCS lookup tool mirrors current CMS data for quick reference. Neither replaces the official CMS file, but both are useful for a fast check.

Our HCPCS code billing guides cover other wheelchair part codes in the same format as this page, with modifiers and denials for each.

What K0044 covers and what it excludes

K0044 covers one part: The upper hanger bracket of a standard footrest. The code applies only when that bracket is supplied on its own to replace the same part on an existing wheelchair.

Covered under K0044: A replacement upper hanger bracket for a swing-away or detachable footrest, fitted because the original is broken, worn or lost.

Excluded from K0044: These items are billed under a different code, or not billed separately at all.

• A footrest supplied with a new wheelchair base, which CMS treats as included in the base code
• A complete replacement footrest assembly, which is K0045
• The lower extension tube on its own, which is K0043
• A replacement standard footplate on its own, which is K0042
• Elevating legrest parts, which have their own codes (K0046 and K0047 for the tube and bracket)
• Labor to fit the part, which is billed separately under the DME repair labor code K0739

If the technician replaced more than the bracket, bill each part that went on the chair. Billing K0044 for a full assembly, or K0045 for a single bracket, is wrong code assignment and invites recoupment on review.

K0044 vs. neighboring codes: Choosing the right code

The most common coding error with K0044 is confusing it with the other footrest and legrest replacement codes. Each code names one physical part, so the choice turns on what was removed from the chair and what replaced it.

K0044 and K0047 are the pair most often mixed up, because both describe an upper hanger bracket. K0044 belongs to a standard footrest, while K0047 belongs to an elevating legrest. NLM’s HCPCS Level II API returns the current descriptor text for each code and can be built into a supplier’s verification step.

The chart below runs the same choice as two questions. It starts with whether the chair is new, then matches the single part that came off.

Medicare coverage criteria for K0044

Medicare Part B covers K0044 under the DMEPOS benefit as a replacement part for a wheelchair. Coverage follows the Wheelchair Options/Accessories LCD (L33792) and its policy article (A52504), which the DME MACs publish jointly.

Medicare pays for replacement parts when they keep a covered wheelchair working. A typical K0044 claim meets these conditions:

• The wheelchair the bracket fits meets Medicare coverage criteria, including the need for it inside the home
• The existing bracket is broken, worn or lost, and the footrest can’t be used safely without a new one
• The new bracket replaces the same part, which the RB modifier reports on the claim
• The patient’s medical record supports continued use of the wheelchair
• The wheelchair is not in a capped rental period, when repairs are the supplier’s job and are included in the rental payment

If the patient needs the wheelchair only outside the home, the policy article tells suppliers to add the GY modifier to every accessory code. That claim then denies as outside the benefit, and the patient or a secondary payer takes responsibility.

K0044 documentation requirements

Documentation for K0044 has to be in the file before the claim goes out. Meeting the billing compliance requirements from the start avoids the rework cycle.

The table below reflects the standard DME MAC documentation rules for a wheelchair replacement part. Check the policy article for any contractor-specific additions.

The repair justification is the line reviewers look for first on replacement parts. A note that reads “bracket replaced” shows what was done. It doesn’t show why Medicare should pay for it.

Required modifiers when billing K0044

Modifier selection on K0044 decides whether Medicare pays the line, holds it, or denies it. Policy article A52504 sets the rules, and the RB modifier carries the most weight on a replacement part.

GY can’t sit on the same line as KX, GA or GZ. Adding KX without supporting documentation is a false attestation and creates audit risk. Check the current policy article before each claim cycle, as modifier rules change with policy revisions.

Prior authorization and advance beneficiary notice rules

CMS keeps a Required Prior Authorization List for certain DMEPOS items, and it updates that list over time. The list has focused on higher-cost items such as power mobility devices rather than replacement parts. Check the current list before you assume a K0044 claim needs no authorization.

Completing insurance eligibility verification before ordering the part also shows whether the patient has active Part B coverage on the date of delivery.

When an ABN is required: If you expect Medicare to deny the K0044 claim, issue a valid Advance Beneficiary Notice of Noncoverage (ABN) before delivery. That covers a chair that may not meet coverage criteria, or a replacement the record doesn’t support.

• Issue the ABN before the part is provided, not after a denial is received
• Use the current CMS-approved ABN form (CMS-R-131)
• Document the cost estimate and the reason for expected non-coverage on the ABN
• Obtain the patient’s signature and give them a copy
• Add the GA modifier to the claim when an ABN is on file
• Retain the signed ABN in the patient’s file for the payer’s required retention period

An ABN obtained after delivery is invalid and doesn’t protect the supplier from liability for the cost of the part.

How to submit a K0044 billing claim: Step-by-step guide

K0044 claims are submitted by enrolled DMEPOS suppliers on the CMS-1500 paper form or its electronic equivalent, the 837P transaction. The supplier needs an active enrollment with the National Supplier Clearinghouse and the DME MAC for the patient’s state.

Using structured DME claims management software reduces the field-level errors that trigger automated edits at the DME MAC.

1. Confirm the written order is on file and dated before the date of delivery.
2. Verify eligibility and active Part B coverage for the date of service.
3. Confirm what was replaced: Bill K0044 only if the upper hanger bracket alone was fitted on a standard footrest.
4. Add the modifiers: RB for the replacement part, then KX, GA, GZ or GY according to coverage status.
5. Enter units: One unit per bracket replaced, so two brackets on the same chair are two units.
6. Enter the date of delivery as the date of service.
7. Link the diagnosis codes that explain why the patient needs the wheelchair, with the primary diagnosis in position 1.
8. Complete supplier details: NPI in box 33a and the place of service, usually 12 for the patient’s home.
9. Retain all documentation, including the order, repair justification, proof of delivery and any ABN, for at least seven years.

The CMS DMEPOS fee schedule files list the current allowable amounts for K-series codes by state. Check them before you submit. The Physician Fee Schedule doesn’t price DMEPOS items, so a search there won’t return a K0044 rate.

Medicare reimbursement rate and fee schedule for K0044

Medicare reimburses K0044 under the DMEPOS fee schedule, which CMS publishes each year. The allowable amount varies by state, and rural and non-rural rates can differ.

Where a competitive bidding program applies to the product category, the program rate replaces the fee schedule amount. Only contract suppliers can then bill Medicare for that category in the area.

Allowable amounts for K0044 change each year and vary by state. Download the current DMEPOS fee schedule file rather than relying on prior-year figures.

Common K0044 claim denial reasons and how to fix them

K0044 denials cluster around three root causes: The wrong footrest code, a missing or wrong modifier, and no record of why the old bracket failed. Most are preventable when the order comes in. Structured denial management workflows that track root causes by code help suppliers spot repeat patterns.

For a CO-50 denial on a supported claim, send the redetermination with the full repair record and proof of delivery. Show what failed, why it couldn’t be repaired, and why the patient still needs the chair.

Submitting a clean claim from the start, with modifiers, units and diagnosis codes checked before transmission, removes the most common denial triggers.

How Pabau keeps K0044 replacement claims documented and on track

Replacement-part claims are small, so they often get the least attention. The order sits in one folder, the repair note in a technician’s email, and the modifier rule in someone’s head. Months later, a records request means piecing it back together.

Pabau, the practice management platform we build, raises each claim from the patient’s invoice. The claim sits on the same record as their notes and files. Claim validation checks for missing or invalid details before the claim leaves for the clearinghouse. A rejected claim is flagged Needs action, with a link to the field that needs fixing.

US practices submit CMS-1500 claims through Claim.MD and follow every claim from Pending to Paid on one dashboard. Your team spends less time chasing small K0044 lines, and the paperwork is ready when a reviewer asks.

Keep every replacement-part claim audit-ready

Pabau raises claims from the patient’s invoice, checks them before submission and flags rejections for a quick fix. So K0044 lines get paid without the rework.

Conclusion

K0044 is a narrow code, and that is where the risk sits. It pays for one bracket on one standard footrest, so the claim succeeds only if the part, the modifier and the repair record agree.

Treat the technician’s note as part of the claim itself. A bracket logged with what failed and why it couldn’t be fixed rarely draws a denial.
