HCPCS Code E2622: Skin Protection Wheelchair Seat Cushion, Adjustable, Width Less Than 22 Inches, Any Depth

They're the same HCPCS code in a way, except that E2623 is for cushions with a width of 22 inches or greater.

It can take up to an hour to do the fitting and adjust it.

It has to be fitted perfectly because it might not do what it's supposed to, and the patient might still suffer skin irritations or get pressure sores. It'll be the same if it isn't maintained properly.
