The rules say that plans must pay for a medical service or item if regular Medicare would pay for it in this case.
You can find this rule at 42 Code of Federal Regulations (CFR) Section 422.101.

The rules say that all of the following basic criteria (A-C) must be met for a power mobility device or a pushrim
activated power assist device to be covered. Additional coverage criteria for specific devices are listed
below.

A. The beneficiary has a mobility limitation that significantly impairs his/her ability to 
participate in one or
more mobility-related activities of daily living (MRADLs) such as toileting, feeding, dressing, 
grooming, and bathing in customary locations in the home. A mobility limitation is one that:
o Prevents the beneficiary from accomplishing an MRADL entirely, or
o Places the beneficiary at reasonably determined heightened risk of morbidity or mortality 
secondary to the attempts to perform an MRADL; or
o Prevents the beneficiary from completing an MRADL within a reasonable time frame.
B. The beneficiary's mobility limitation cannot be sufficiently and safely resolved by the use of 
an appropriately fitted cane or walker.

C. The beneficiary does not have sufficient upper extremity function to self-propel an optimally- 
configured manual wheelchair in the home to perform MRADLs during a typical day.
o Limitations of strength, endurance, range of motion, or coordination, presence of pain, or 
deformity or absence of one or both upper extremities are relevant to the assessment of upper 
extremity function.
o An optimally-configured manual wheelchair is one with an appropriate wheelbase, device
weight, seating options, and other appropriate nonpowered accessories.

A POV is covered if all of the basic coverage criteria (A-C) have been met and if criteria D-I are also met.

D. The beneficiary is able to:
o Safely transfer to and from a POV, and
o Operate the tiller steering system, and
o Maintain postural stability and position while operating the POV in the home.

E. The beneficiary's mental capabilities (e.g., cognition, judgment) and physical capabilities (e.g., vision)
are sufficient for safe mobility using a POV in the home.

F. The beneficiary's home provides adequate access between rooms, maneuvering space, and surfaces for
the operation of the POV that is provided.

G. The beneficiary's weight is less than or equal to the weight capacity of the POV that is provided and
greater than or equal to 95% of the weight capacity of the next lower weight class POV - i.e., a Heavy
Duty POV is covered for a beneficiary weighing 285 - 450 pounds; a Very Heavy Duty POV is covered
for a beneficiary weighing 428 - 600 pounds.

H. Use of a POV will significantly improve the beneficiary's ability to participate in MRADLs and the
beneficiary will use it in the home.

I. The beneficiary has not expressed an unwillingness to use a POV in the home.

If a POV will be used inside the home and coverage criteria A-I are not met, it will be denied as not reasonable
and necessary.

Group 2 POVs (K0806, K0807, K0808) have added capabilities that are not needed for use in the home.
Therefore, if a Group 2 POV is provided it will be denied as not reasonable and necessary.

If a POV will only be used outside the home, see related Policy Article for information concerning
noncoverage.

A power wheelchair is covered if:

a. All of the basic coverage criteria (A-C) are met; and
b. The beneficiary does not meet coverage criterion D, E, or F for a POV; and
c. Either criterion J or K is met; and
d. Criteria L, M, N, and O are met; and
e. Any coverage criteria pertaining to the specific wheelchair type (see below) are met.

J. The beneficiary has the mental and physical capabilities to safely operate the power wheelchair that is
provided; or

K. If the beneficiary is unable to safely operate the power wheelchair, the beneficiary has a caregiver who
is unable to adequately propel an optimally configured manual wheelchair, but is available, willing, and
able to safely operate the power wheelchair that is provided; and

L. The beneficiary's weight is less than or equal to the weight capacity of the power wheelchair that is
provided and greater than or equal to 95% of the weight capacity of the next lower weight class PWC -
i.e., a Heavy Duty PWC is covered for a beneficiary weighing 285 - 450 pounds; a Very Heavy Duty
PWC is covered for a beneficiary weighing 428 - 600 pounds; an Extra Heavy Duty PWC is covered
for a beneficiary weighing 570 pounds or more.

M. The beneficiary's home provides adequate access between rooms, maneuvering space, and surfaces for
the operation of the power wheelchair that is provided.

N. Use of a power wheelchair will significantly improve the beneficiary's ability to participate in
MRADLs and the beneficiary will use it in the home. For beneficiaries with severe cognitive and/or
physical impairments, participation in MRADLs may require the assistance of a caregiver.

O. The beneficiary has not expressed an unwillingness to use a power wheelchair in the home.

If a PWC will be used inside the home and if coverage criteria (a)-(e) are not met, it will be denied as not
reasonable and necessary.
