HCPCS code K0814 – Group 1 standard portable captain's chair power wheelchair

Key takeaways

HCPCS code K0814 describes a group 1 standard portable power wheelchair with a captain’s chair seat, billed under Medicare Part B for home use.

Prior authorization is mandatory before delivery, and a chair delivered without a provisional affirmation is not paid, whatever the medical need.

Append the KX modifier only when the standard written order, the face-to-face notes and the prior authorization affirmation are complete and on file.

Portability and the captain’s chair seat set K0814 apart, so K0813 and K0816 are the codes it is most often confused with.

Practice software such as Pabau keeps the face-to-face notes, signed orders and billing steps for each patient in one record.

What HCPCS code K0814 covers

HCPCS code K0814 is the Level II code for a group 1 standard power wheelchair that is portable and has a captain’s chair seat.

It covers patients up to and including 300 pounds. The Centers for Medicare & Medicaid Services (CMS) maintain the code, which sits in the K0813–K0899 power wheelchair range. The table below summarizes the official descriptor and code family.

“Group 1 standard” is the lowest-complexity power wheelchair tier CMS defines. A group 1 chair must reach a minimum speed of about 3 mph and a range of at least 5 miles per charge. K0814 adds a weight capacity of up to 300 pounds.

“Portable” means the chair can be broken down for transport without tools. “Captain’s chair” refers to an automotive-style seat with fixed armrests and a defined seat back. That seat is what separates K0814 from K0813, the portable chair with a sling or solid seat and back.

The code comes from the CMS HCPCS Level II code set, which CMS updates every year. Confirm the code’s active status against the current Alpha-Numeric HCPCS file before you submit claims. Neighboring wheelchair and DME codes are listed in our index of HCPCS codes.

How Medicare reimburses K0814 in 2026

Medicare Part B pays 80% of the allowed amount for K0814 once the annual deductible is met. The beneficiary pays the remaining 20% coinsurance. Check the exact 2026 allowed amount on the CMS DMEPOS fee schedule, because rates change each January and vary by state.

Since January 1, 2011, Medicare has paid for standard power wheelchairs, including K0814, on a capped rental basis only. Bill the RR modifier; outright purchase is no longer an option.

Medicare coverage criteria and medical necessity for K0814

Medicare covers K0814 for beneficiaries with a significant mobility limitation that a cane, walker or manual wheelchair cannot adequately address. The Power Mobility Devices Local Coverage Determination (LCD) sets the clinical criteria that suppliers and clinicians must document. The three core conditions are:

• The patient has a mobility limitation that significantly impairs one or more mobility-related activities of daily living (MRADLs) in the home.
• The patient’s condition will not improve with less supportive mobility equipment (cane, walker, manual wheelchair).
• The patient has the physical and cognitive ability to safely operate a power wheelchair in the home environment.

The LCD also excludes devices when the underlying condition is reversible and the length of need is under three months. Review the LCD published by your DME Medicare Administrative Contractor (MAC), CGS or Noridian, before you submit.

Supporting ICD-10 diagnosis codes for K0814 claims

Every K0814 claim must include at least one ICD-10 diagnosis code that supports medical necessity under the LCD. The table below lists commonly accepted codes. Verify each one against the active LCD for your jurisdiction before you submit.

Required documentation before submitting a K0814 claim

Incomplete documentation is the largest single driver of K0814 denials. Solid medical billing compliance starts before the device ships, so gather each item below before you submit the claim.

1. Face-to-face examination report. The treating physician or non-physician practitioner (NPP) completes it within 6 months before the written order date. It must document the patient’s mobility limitations in the home, not just in a clinical setting.
2. Standard written order (SWO). It lists the beneficiary’s name or Medicare Beneficiary Identifier (MBI), the order date and a general description of the item. It also gives the quantity, the treating practitioner’s name or NPI, and the practitioner’s signature.
3. Written order prior to delivery. The supplier must hold the SWO and the face-to-face documentation before the chair is delivered. Power mobility devices no longer use a Certificate of Medical Necessity (CMN).
4. Prior authorization affirmation. A copy of the provisional affirmation from the DME MAC must be on file before the device is delivered.
5. Proof of delivery. A delivery receipt signed by the beneficiary or an authorized representative at the time of delivery.

Face-to-face examination requirements

The face-to-face encounter can take place in person or through a Medicare-approved telehealth visit that meets the telehealth rules. The treating physician or NPP must document the following in the exam notes:

• The patient’s primary diagnosis causing the mobility limitation
• Functional limitations in MRADLs specifically observed or reported in the home setting
• Why less supportive equipment is insufficient
• The patient’s ability to safely operate a power wheelchair

The supplier must receive those exam notes before delivery and keep them on file for a MAC audit.

Does K0814 require prior authorization?

Yes. K0814 is on the CMS required prior authorization list for power mobility devices. The supplier must receive a provisional affirmation from the DME MAC before delivering the chair. Delivery before affirmation results in non-payment, and this program offers no retroactive authorization.

A prior authorization request has two possible outcomes:

• Provisional affirmation: The DME MAC confirms the request meets coverage requirements. The claim can be billed after delivery.
• Non-affirmation: The DME MAC finds the coverage requirements unmet. The supplier may resubmit with more documentation but cannot deliver the device until it is affirmed.

Medicare Advantage plans set their own prior authorization rules, which may differ from traditional Medicare. Check the plan’s prior authorization process before you start a request.

How to bill K0814, step by step

Billing K0814 through clean medical billing workflows means completing each step in order. Skipped or out-of-order steps cause most avoidable denials. Here is the standard sequence for DMEPOS suppliers:

1. Verify the patient’s Medicare Part B eligibility, and confirm the beneficiary is not in a Medicare Advantage plan that routes DME differently.
2. Check whether a competitive bidding contract covers power wheelchairs where the beneficiary lives. If one does, confirm your organization holds a contract for that area.
3. Obtain the treating practitioner’s face-to-face examination notes and the standard written order.
4. Submit the prior authorization request to the DME MAC and wait for a provisional affirmation.
5. Deliver the device, obtain a signed proof of delivery, and retain all documentation.
6. Submit the claim on the CMS-1500 or 837P with place of service 12 (home) and the payment modifier. Add KX when documentation meets LCD criteria.

Run a clean claim check before step 6. It catches a missing modifier or a wrong place of service before the claim reaches the DME MAC.

HCPCS modifiers used with K0814

The modifier on a K0814 claim signals rental status and documentation compliance. A wrong modifier or a missing KX is a frequent denial trigger for this code.

The KX modifier deserves special attention. Appending it without the documentation on file is a false assertion to Medicare, and it can trigger a program integrity review. Use KX only when the face-to-face notes, the standard written order and the prior authorization affirmation are complete and on file.

K0814 vs related power wheelchair codes

The standard power wheelchair codes differ by one or two features, which makes them easy to confuse. Two features separate K0814 from its neighbors: portability and seat type. The table below shows when each code applies.

The most common miscoding error is billing K0814 for a chair that differs in one feature. The non-portable captain’s chair is K0816, and the portable sling/solid-seat chair is K0813. Billing K0820 or K0821 for a chair that only meets group 1 specifications is the same mistake.

The code billed must match the chair delivered. Billing for a chair the patient did not receive is a False Claims Act issue, not merely a coding error. The grid below maps the four group 1 standard codes to the two questions that decide between them.

Common reasons K0814 claims are denied and how to avoid them

K0814 denials cluster around the same preventable errors. Effective denial management strategies start with the root cause behind each denial reason.

Does competitive bidding apply to K0814?

Not under current contracts. The current round of the DMEPOS Competitive Bidding Program does not cover standard power wheelchairs, and the earlier contracts have lapsed. Any Medicare-enrolled supplier can therefore bill K0814 at the fee schedule rate.

If a future round brings power wheelchairs into a competitive bidding area (CBA), two rules would apply there:

• Contract suppliers only. Only suppliers holding a power wheelchair contract for that CBA could bill Medicare for K0814 there.
• Beneficiary location governs. CBA rules follow the beneficiary’s home address, not the supplier’s location.

To check a beneficiary’s address against active CBAs, use the Competitive Bidding Implementation Contractor (CBIC) look-up tool. Tracking electronic remittance advice codes on K0814 claims also surfaces location-related denials early.

How Pabau keeps K0814 documentation together

Much of the K0814 paperwork starts in the treating practitioner’s office. The face-to-face notes and the signed standard written order both have to reach the supplier before the chair ships.

Pabau, the practice management and EHR platform we build, keeps those documents in one patient record. Clinicians can record the exam on a custom form built around the LCD criteria. Signed orders and forms sit beside the notes, ready to share.

With Pabau’s claims management software, the documentation and billing steps for each patient stay in one place. A missing order is easier to spot before anything is submitted.

Conclusion

K0814 claims are won or lost before the chair ships. When the written order, face-to-face notes and prior authorization are in place at delivery, KX is honest and payment holds up on audit.

The trade-off is time up front. Waiting for a provisional affirmation delays delivery, but billing without one leaves no route to payment. Check the code against the chair at delivery too, because portability and seat type decide between K0813, K0814 and K0816.
