Can someone help me in verifing if which hcpcs code K0001 or E1130 is the correct billing for purchase of a standard wheelchair.?

Neither K0001 nor E1130 is the correct code for purchase of a standard wheelchair. The correct code is E0983.

K0001 is the code for a manual wheelchair, which is a wheelchair that is propelled by the user's hands.

E1130 is the code for a power wheelchair, which is a wheelchair that is powered by a battery.

A standard wheelchair is a wheelchair that is not motorized and does not have any special features.
