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 a power seat elevation feature (E2300) and power standing feature (E2301) are non-covered 
because they are not primarily medical in nature. If a wheelchair has an electrical connection device described 
by code E2310 or E2311 and if the sole function of the connection is for a power seat elevation or power 
standing feature, it will be denied as non-covered. 
 
A power seat elevation system (E2300) includes: a motor and related electronics with or without variable speed 
programmability; a switch control which is independent of the power wheelchair drive control interface; any 
hardware that is needed to attach the seating system to the wheelchair base. It must provide a seat elevation of 
at least 6 inches. 
 
For power wheelchairs which are capable of being upgraded to an expandable controller (K0835, K0836, 
K0837, K0838, K0839, K0840, K0841, K0842, K0843, K0848, K0849, K0850, K0851, K0852, K0853, 
K0854, K0855, K0856 K0857, K0858, K0859, K0860, K0861 K0862, K0863, K0864, K0868, K0869, K0870, 
K0871, K0877, K0878, K0879, K0880, K0884, K0885, K0886, K0890, K0891), E2377 is used if an 
expandable controller is provided at the time of initial issue. Code E2376 is used with complete replacement of 
an expandable controller. 
 
A harness (E2313) describes all of the wires, fuse boxes, fuses, circuits, switches, etc. that are required for the 
operation of an expandable controller. It also includes all the necessary fasteners, connectors, and mounting 
hardware. Code E2313 is separately billable in addition to an expandable controller both at initial issue and 
with complete replacement of the expandable controller. Code K0108 must not be used for any component or 
feature of an expandable controller at the time of initial issue. The reimbursement for any type of complete 
expandable controller is included in the allowance for codes E2377/E2376 plus E2313. However, if individual 
components of the harness are replaced, code K0108 should be used. 
 
The interfaces described by codes E2312, E2321, E2322, E2325, E2327, E2328, E2329, E2330, E2373, E2374, 
E2375, E2376, E2377 must have programmable control parameters for speed adjustment, tremor dampening, 
acceleration control, and braking. 
 
Codes E2310 and E2311 describe the electronic components that allow the beneficiary to control two or more 
of the following motors from a single interface (e.g., proportional joystick, touchpad, or non-proportional 
interface): power wheelchair drive, power tilt, power recline, power shear reduction, power leg elevation, 
power seat elevation, power standing. It includes a function selection switch which allows the beneficiary to 
select the motor that is being controlled and an indicator feature to visually show which function has been 
selected. When the wheelchair drive function has been selected, the indicator feature may also show the 
direction that has been selected (forward, reverse, left, right). This indicator feature may be in a separate 
display box or may be integrated into the wheelchair interface. Payment for the code includes an allowance for 
fixed mounting hardware for the control box and for the display box (if present). 
 
An expandable controller is capable of accommodating one or more of the following additional functions: 
 
    Other types of proportional input devices (e.g., mini-proportional or compact joysticks, touchpads, chin 
control, head control, etc.) 
 
    Non-proportional input devices (e.g., sip and puff, head array, etc.) 
 
    Operate 3 or more powered seating actuators through the drive control. (Note: Control of the power seating 
actuators though the Control Input Device would require the use of an additional component, E2310 or E2311.) 
 
A power leg elevation feature (E1010, E1012) involves dedicated motor(s) and related electronics with or 
without variable speed programmability which allows the legrest to be raised and lowered independently of the 
recline and/or tilt of the seating system. It includes a switch control which may or may not be integrated with 
the power tilt and/or recline control(s). It includes either articulating or non-articulating legrests. The unit of 
service of code E1010 is a pair. The unit of service for code E1012 is each. 
 
HCPCS code E1012 includes all components of the leg rest, including fixed angle footplates and foot 
platforms. Adjustable angle footplates coded K0040 (ADJUSTABLE ANGLE FOOTPLATE, EACH) are 
separately payable when provided with leg rests coded as E1012. You can find these rules in the Local 
Coverage Article Wheelchair Options/Accessories - Policy Article A52504. 
 
If the prefabricated seat cushion, prefabricated back cushion, or a brand name custom fabricated seat or back 
cushion has not received a written CVR from the PDAC or if the PDAC has reviewed and determined that the 
product does not meet the criteria for the code, then it must be billed with code K0669. You can find this rule 
in the Local Coverage Article Wheelchair Seating - Policy Article A52505.

The Plan contract says that the Plan covers items and services in accordance with Medicare rules.
