(D) Payment for the code includes an allowance for fixed mounting hardware for the control box and for the display box (if present);
(E) When a switch is medically appropriate and a client has adequate hand motor skills, a switch shall be considered the least costly alternative;
(F) E2310 or E2311 may be considered for coverage when a client does not have hand motor skills or presents with cognitive deficits, contractures, or limitation of movement patterns that prevents operation of a switch;
(G) In addition, an alternate switching system must be medically appropriate and not hand controlled (not running through a joystick).
(m) Power Wheelchair Drive Control Systems:
(A) The term interface in the code narrative and definitions describes the mechanism for controlling the movement of a power wheelchair. Examples of interfaces include but are not limited to joystick, sip and puff, chin control, head control, etc.;
(B) A proportional interface is one in which the direction and amount of movement by the client controls the direction and speed of the wheelchair. One example of a proportional interface is a standard joystick;
(C) A non-proportional interface is one that involves a number of switches. Selecting a particular switch determines the direction of the wheelchair, but the speed is pre-programmed. One example of a non-proportional interface is a sip-and-puff mechanism;
(D) The term controller describes the microprocessor and other related electronics that receive and interpret input from the joystick (or other drive control interface) and convert that input into power output to the motor and gears in the power wheelchair base;
(E) A switch is an electronic device that turns power to a particular function either “on” or “off.” The external component of a switch may be either mechanical or non-mechanical. Mechanical switches involve physical contact in order to be activated. Examples of the external components of mechanical switches include but are not limited to toggle, button, ribbon, etc. Examples of the external components of non-mechanical switches include but are not limited to proximity, infrared, etc. Some of the codes include multiple switches. In those situations, each functional switch may have its own external component, or multiple functional switches may be integrated into a single external switch component, or multiple functional switches may be integrated into the wheelchair control interface without having a distinct external switch component;
(F) A stop switch allows for an emergency stop when a wheelchair with a non-proportional interface is operating in the latched mode. (Latched mode is when the wheelchair continues to move without the patient having to continually activate the interface.) This switch is sometimes referred to as a kill switch;
(G) A direction change switch allows the client to change the direction that is controlled by another separate switch or by a mechanical proportional head control interface. For example, it allows a switch to initiate forward movement one time and backward movement another time;
(H) A function selection switch allows the client to determine what operation is being controlled by the interface at any particular time. Operations may include but are not limited to drive forward, drive backward, tilt forward, recline backward, etc.;
(I) An integrated proportional joystick and controller is an electronics package in which a joystick and controller electronics are in a single box that is mounted on the arm of the wheelchair;
(J) The interfaces described by codes E2321-E2322, E2325, and E2327-E2330 must have programmable control parameters for speed adjustment, tremor dampening, acceleration control, and braking;
(K) A remote joystick (E2321) is one in which the joystick is in one box that is mounted on the arm of the wheelchair and the controller electronics are located in a different box that is typically located under the seat of the wheelchair;
(L) When code E2321 is used for a chin control interface, the chin cup is billed separately with code E2324;
(M) Code E2322 describes a system of 3-5 mechanical switches that are activated by the client touching the switch. The switch that is selected determines the direction of the wheelchair. A mechanical stop switch and a mechanical direction change switch, if provided, are included in the allowance for the code;
(N) Code E2323 includes prefabricated joystick handles that have shapes other than a straight stick, e.g., U shape or T shape or that have some other nonstandard feature, e.g., flexible shaft;
(O) A sip and puff interface (E2325) is a non-proportional interface in which the client holds a tube in their mouth and controls the wheelchair by either sucking in (sip) or blowing out (puff). A mechanical stop switch is included in the allowance for the code. E2325 does not include the breath tube kit that is described by code E2326;
(P) A proportional, mechanical head control interface (E2327) is one in which a headrest is attached to a joystick-like device. The direction and amount of movement of the client’s head pressing on the headrest control the direction and speed of the wheelchair. A mechanical direction control switch is included in the code;
(Q) A proportional, electronic head control interface (E2328) is one in which a client’s head movements are sensed by a box placed behind the client’s head. The direction and amount of movement of the client’s head (which does not come in contact with the box) control the direction and speed of the wheelchair. A proportional, electronic extremity control interface (E2328) is one in which the direction and amount of movement of the client’s arm or leg control the direction and speed of the wheelchair;
(R) A non-proportional, contact switch head control interface (E2329) is one in which a client activates one of three mechanical switches placed around the back and sides of their head. These switches are activated by pressure of the head against the switch. The switch that is selected determines the direction of the wheelchair. A mechanical stop switch and a mechanical direction change switch are included in the allowance for the code;
(S) A non-proportional, proximity switch head control interface (E2330) is one in which a client activates one of three switches placed around the back and sides of their head. These switches are activated by movement of the head toward the switch, though the head does not touch the switch. The switch that is selected determines the direction of the wheelchair. A mechanical stop switch and a mechanical direction change switch are included in the allowance for the code;
(T) The KC modifier (replacement of special power wheelchair interface):
(i) Is used in the following situations:
(I) Due to a change in the client’s condition an integrated joystick and controller is being replaced by another drive control interface, e.g., remote joystick, head control, sip and puff, etc.; or
(II) The client has a drive control interface described by codes E2320-E2322, E2325, or E2327-E2330 and both the interface (e.g., joystick, head control, sip and puff), and the controller electronics are being replaced due to irreparable damage.
(ii) The KC modifier is never used at the time of initial issue of a wheelchair;
(iii) The KC modifier specifically states replacement; therefore, the RP modifier is not required.
(n) Other power wheelchair accessories. An electronic interface (E2351) to allow a speech generating device to be operated by the power wheelchair control interface may be covered if the client has a covered speech generating device (See chapter 410, division 129, Speech-Language Pathology, Audiology and Hearing Aid Services.);
(o) Miscellaneous accessories:
(A) Anti-rollback device (E0974) is covered if the client propels himself and needs the device because of ramps;
(B) A safety belt/pelvic strap (E0978) is covered if the client has weak upper body muscles, upper body instability, or muscle spasticity that requires use of this item for proper positioning;
(C) A shoulder harness/straps or chest strap (E0960) and a safety belt/pelvic strap (E0978) are covered only to treat a client’s medical symptoms:
(i) A medical symptom is defined as an indication or characteristic of a physical or psychological condition;
(ii) E0960 and E0978 are not covered when intended for use as a physical restraint or for purposes intended for discipline or convenience of others.
(D) One example (not all-inclusive) of a covered indication for swingaway, retractable, or removable hardware (E1028) would be to move the component out of the way so that a client could perform a slide transfer to a chair or bed;
(E) A fully reclining back option (E1226) is covered if the client spends at least two hours per day in the wheelchair and has one or more of the following conditions/needs:
(i) Quadriplegia;
(ii) Fixed hip angle;
(iii) Trunk or lower extremity casts/braces that require the reclining back feature for positioning;
(iv) Excess extensor tone of the trunk muscles; or
(v) The need to rest in a recumbent position two or more times during the day, and transfer between wheelchair and bed is very difficult.
(2) Documentation Requirements. Submit documentation that supports coverage criteria in this rule are met and the specified information as follows with the prior authorization (PA) request:
(a) When code K0108 is billed, a narrative description of the item, the manufacturer, the model name or number (if applicable), and information justifying the medical appropriateness for the item;
(b) Options/accessories for individual consideration might include documentation on the client’s diagnosis, the client’s abilities and limitations as they relate to the equipment (e.g., degree of independence/dependence, frequency and nature of the activities the client performs, etc.), the duration of the condition, the expected prognosis, past experience using similar equipment;
(c) For a custom-fabricated seat cushion:
(A) A comprehensive written evaluation by a licensed clinician (who is not an employee of or otherwise paid by a DMEPOS provider) that clearly explains why a prefabricated seating system is not sufficient to meet the client’s seating and positioning needs;
(B) Diagnostic reports that support the medical condition;
(C) Dated and clear photographs;
(D) Body contour measurements.
(d) Documentation that the coverage criteria in this rule have been met must be present in the client’s medical record. This documentation and any additional medical information from the DMEPOS provider must be made available to the Division upon request.
