CMC Funding & Insurance for Mobility Equipment 3 — Questions and Answers
Question 1: Which HCPCS code grouping is used specifically for Complex Rehab Technology (CRT) power wheelchairs to distinguish them from standard power chairs?
- K0835–K0864 (Group 3 and Group 4 power wheelchairs) (Correct answer)
- E1161–E1200 (lightweight manual chairs)
- K0001–K0004 (standard manual wheelchairs)
- L5100–L5999 (lower limb prosthetics)
Correct answer: K0835–K0864 (Group 3 and Group 4 power wheelchairs)
HCPCS K0835–K0864 cover Group 3 and Group 4 power wheelchairs that qualify as CRT, distinguishing them from Group 1 and 2 standard chairs.
Question 2: A client is denied Medicare coverage for a power wheelchair because the clinical documentation does not demonstrate the inability to self-propel a manual chair. This reflects which Medicare coverage criterion?
- The patient must be unable to use a less costly alternative device (Correct answer)
- The patient must have a diagnosis on the CMS approved condition list
- The patient must have received the equipment from a Medicare-enrolled supplier
- The patient must have a documented fall history within 12 months
Correct answer: The patient must be unable to use a less costly alternative device
Medicare applies a least-costly alternative principle, requiring documentation that less complex equipment cannot meet the patient's mobility needs before approving a power chair.
Question 3: What is 'assignment' in Medicare DME billing, and why does it matter for patients?
- The supplier agrees to accept Medicare's approved amount as full payment, limiting patient out-of-pocket costs (Correct answer)
- The patient assigns their doctor the right to order any equipment needed
- The supplier assigns a claim number for tracking purposes
- Medicare assigns the patient to a specific DME contractor
Correct answer: The supplier agrees to accept Medicare's approved amount as full payment, limiting patient out-of-pocket costs
When a supplier accepts assignment, they cannot bill the patient more than the Medicare copay (20%) and deductible, protecting patients from balance billing.
Question 4: A Medicaid waiver program such as HCBS (Home and Community-Based Services) is used primarily to fund which type of mobility equipment scenario?
- Equipment that enables individuals to remain in the community rather than institutional settings (Correct answer)
- Inpatient rehabilitation equipment for acute hospital stays
- Equipment exclusively for pediatric beneficiaries under age 18
- Replacement parts for Medicare-approved power wheelchairs only
Correct answer: Equipment that enables individuals to remain in the community rather than institutional settings
HCBS waivers allow states to fund services and equipment that help individuals with disabilities live in community rather than nursing facility settings.
Question 5: Which federal act prohibits insurers from imposing lifetime or annual dollar limits on essential health benefits, directly impacting funding for mobility equipment?
- Affordable Care Act (ACA) (Correct answer)
- Americans with Disabilities Act (ADA)
- Rehabilitation Act of 1973
- Technology-Related Assistance for Individuals with Disabilities Act
Correct answer: Affordable Care Act (ACA)
The ACA prohibits lifetime and annual dollar limits on essential health benefits, ensuring ongoing coverage for medically necessary mobility equipment is not capped.
Question 6: A supplier provides a loaner manual wheelchair while a client's power chair insurance claim is pending. Which concept describes this practice?
- Temporary/loaner equipment provision during claim adjudication (Correct answer)
- Capped rental arrangement under Medicare's 13-month rule
- Advance beneficiary notice (ABN) waiver of liability
- Assignment of benefits transfer
Correct answer: Temporary/loaner equipment provision during claim adjudication
Providing a loaner ensures continued mobility access during the claim review period without committing to the final dispensing arrangement.
Question 7: Under Medicare's Competitive Bidding Program for DME, which geographic area determines the reimbursement rate a supplier receives for a standard manual wheelchair?
- The Competitive Bidding Area (CBA) where the item is delivered to the beneficiary (Correct answer)
- The supplier's primary business address regardless of delivery location
- The CMS national fee schedule rate uniformly applied across all states
- The state where the prescribing physician is licensed
Correct answer: The Competitive Bidding Area (CBA) where the item is delivered to the beneficiary
Medicare's competitive bidding rates are set by the CBA (metropolitan statistical area) where the equipment is actually delivered to the beneficiary.
