HCPCS code K0822 – Group 2 standard power wheelchair

Key takeaways

HCPCS code K0822 covers a group 2 standard power wheelchair with a sling or solid seat and back, for patients up to 300 pounds.

The face-to-face exam must fall within 6 months before the written order, with notes and order reaching the supplier within 45 days of the exam.

A standard written order must be in place before delivery, and K0822 needs an affirmed prior authorization request in every state.

Add KX only when every LCD L33789 criterion is met and documented, and pair RR with KH, KI or KJ by rental month.

Pabau, the practice management platform we build, pre-fills the claim from the patient record and checks required fields before you send it.

HCPCS code K0822 is the group 2 standard power wheelchair code

HCPCS code K0822 is the Level II code for a group 2 standard power wheelchair with a sling or solid seat and back. It covers patients up to 300 pounds. The official CMS descriptor reads: Power wheelchair, group 2 standard, sling/solid seat/back, patient weight capacity up to and including 300 pounds.

Group 2 chairs sit in the middle of CMS’s performance groups. They suit patients who can’t manage a cane, walker or manual wheelchair at home, but who don’t need complex rehab seating. Group 3 and higher codes cover complex rehabilitative chairs with extra clinical requirements.

Medicare covers K0822 under LCD L33789 and its policy article A52498. Those two documents define coverage, so keep both open while you build the file.

Seat type and weight decide between K0822 and its neighbors

Two details on the order pick the code: the seat and back type, and the patient’s weight. The table puts K0822 next to the group 2 codes it’s most often confused with, including the portable K0820. It also adds the neighboring group 1 code, K0813.

Two mix-ups cause most coding errors here. A chair with a captain’s chair seat and back belongs under K0823, however similar the base looks. A patient documented above 300 pounds needs the heavy-duty code, K0824.

Either error leaves the billed code out of step with the device on file. The claim is then denied, and you rebill under the correct code.

Medicare covers K0822 when mobility at home is the problem

Under LCD L33789, coverage rests on function, not on the diagnosis alone. The medical record has to show each of these before the claim goes out:

• A mobility limitation at home: the patient can’t complete mobility-related activities of daily living (MRADLs) in a reasonable time. Think toileting, feeding, dressing or bathing.
• Simpler devices won’t solve it: a cane or walker isn’t enough, and the patient can’t self-propel a manual wheelchair well enough to do those tasks.
• Safe operation: the patient can safely operate the power wheelchair, or has a caregiver who can.
• A home that fits the chair: doorways, turning space and floor surfaces allow the chair to be used inside.
• A listed device: the model appears on the PDAC Product Classification List under K0822.

The home test trips up new billers more than any other criterion. A patient who wants the chair mainly for shopping trips or appointments doesn’t meet it, even with a serious diagnosis. The note has to tie the chair to tasks inside the home.

The face-to-face exam and written order have to come first

Medicare requires a face-to-face examination by the treating practitioner within 6 months before the written order. The supplier must then receive the exam notes and the order within 45 days of the exam. This rule comes from Social Security Act Section 1834(a)(1)(E) and policy article A52498.

The exam notes should cover these points, in the practitioner’s own words:

1. The diagnosis and how it limits the patient’s mobility
2. Which MRADLs the patient can’t complete at home, and why a cane, walker or manual chair won’t help
3. Upper-body strength, sitting balance and judgment, so the reader sees the patient can drive the chair safely
4. A clear statement that a power wheelchair is needed for use in the home

After the exam, the same practitioner completes a Standard Written Order (SWO). K0822 is on the CMS list of items that need a Written Order Prior to Delivery (WOPD). The order must exist before the chair arrives.

The old Detailed Written Order no longer applies, since CMS retired it in 2020. If the order is dated after delivery, the claim fails, and no later signature fixes it.

Prior authorization for K0822 applies in every state

Prior authorization trips up more K0822 claims than any modifier does. Here are the answers billers ask for most often.

Is prior authorization required everywhere? Yes. K0822 is on CMS’s Required Prior Authorization List, effective September 1, 2018, nationwide. It applies with every DME MAC.

What happens without it? A claim without an affirmed prior authorization request is denied. There’s no retrospective request to fall back on afterwards.

What if the request comes back non-affirmed? The supplier can fix the missing documentation and resubmit before delivery. Delivering without an affirmation means the claim will be denied.

How a K0822 claim moves from exam to payment

Put the steps in order and the pattern is plain: four of the six happen before the chair leaves the warehouse. The timeline below shows where each document lands.

In practice, the sequence breaks at the handoffs. The exam notes reach the supplier late, or the order arrives before the exam is signed. Date-stamp each document when it lands, and the timeline checks itself.

K0822 modifiers: KX plus the capped rental set

Every K0822 claim carries KX when all LCD coverage criteria are met and documented. The rental modifiers then tell the MAC which month you’re billing.

KX and GA never sit on the same line. Use KX when the criteria are met, and GA or GZ when they aren’t. Without KX, automated edits deny the claim before a reviewer ever sees the file.

Medicare pays K0822 as a 13-month capped rental

Medicare pays K0822 as a capped rental under Social Security Act Section 1834(a). Standard power wheelchairs lost their lump-sum purchase option in January 2011, so the chair is rented month by month.

Medicare pays a monthly rental for up to 13 months. After month 13, the patient owns the chair. From then on, Medicare pays for reasonable repairs and servicing of the patient-owned equipment.

The allowed amount comes from the DMEPOS fee schedule for the supplier’s location, and it varies by state. Check the current figure in the CMS DMEPOS fee schedule. The patient pays 20% coinsurance once the Part B deductible is met.

K0822 documentation auditors check first

Sound medical billing compliance for K0822 means each document is in the file before the claim goes out. The table lists what auditors check and the items auditors commonly find missing.

Before you submit a K0822 claim

Run this quick check on every file. It takes two minutes and catches the denials listed further down.

• Exam date falls within 6 months before the order date
• Order signed by the practitioner who did the exam, and dated before delivery
• Notes and order received within 45 days of the exam
• Affirmed prior authorization on file, with a matching code
• Model checked against the PDAC list under K0822
• Weight documented at 300 pounds or under
• KX added, plus RR and the right month modifier

Diagnosis codes support K0822, but function decides coverage

No diagnosis qualifies a patient for K0822 on its own. LCD L33789 and policy article A52498 define coverage through the MRADL criteria above, not through a list of approved conditions.

That said, certain diagnoses often appear on K0822 claims because they cause lasting mobility limits. Code the condition to full specificity, then let the exam notes show the functional impact.

Why K0822 claims get denied, and the fix for each

Most K0822 denials can be prevented, and the same few causes come up again and again. Good denial management starts with matching each one to its fix.

Your remittance advice names the reason behind each rejection. Matching it against claim denial codes tells you whether to rebill or appeal.

How to appeal a denied K0822 claim, level by level

Medicare’s five-level appeals process applies to denied K0822 claims. Each level has its own deadline, so diary the dates the day the denial arrives.

1. Redetermination: file with the MAC within 120 days of the initial determination. Include every document the denial says is missing.
2. Reconsideration: if the MAC upholds the denial, file with the Qualified Independent Contractor (QIC) within 180 days. The QIC is independent of the MAC.
3. Administrative Law Judge (ALJ) hearing: request it within 60 days of the QIC decision, if the amount in controversy meets the yearly threshold.
4. Medicare Appeals Council: file within 60 days of an unfavorable ALJ decision.
5. Federal district court: available once the lower levels are exhausted and the amount meets the statutory minimum.

At each level, send a cover letter that quotes the LCD L33789 criteria and maps each one to a page in the file. Attach the exam notes, the dated SWO and any new clinical evidence. A medical appeal form keeps that letter consistent from one claim to the next.

Check the PDAC list before you bill K0822

The Pricing, Data Analysis and Coding (PDAC) contractor publishes the Product Classification List. It confirms which wheelchair models meet the technical specifications for each code.

A model that isn’t listed under K0822 can’t be billed as K0822, whatever the brochure says. Check the model on pdac.cms.gov before the order goes to the manufacturer, and keep a screenshot of the listing in the file.

How Pabau helps practices send cleaner K0822 claims

Many practices still copy patient details, codes and dates into a claim form by hand. Each retyped field is a chance for a wrong code or a missing date.

Pabau’s cleaner claims management tools pre-fill the claim form from the patient record, so details flow straight from the chart. Built-in ICD-10, CPT and HCPCS lookup libraries help you find K0822 and the supporting diagnosis codes quickly.

Before you press Send, Pabau checks that the required claim fields are complete. In the US, claims go out through Claim.MD, with eligibility checks up front and ERA payments posted back to the patient record. Your team spends less time rekeying and more time chasing the documents only the practitioner can supply.

Conclusion

K0822 claims are won or lost before the chair ships. If the exam, the written order and the prior authorization line up in that order, the claim itself is the easy part.

So treat delivery as the deadline, not the claim date. Hold any chair whose file is missing a dated order or an affirmed request. A one-week delay costs far less than an appeal that runs through several levels.
