Which HCPCS code is billed for a bathtub wall rail by a home health agency?

The correct choice for billing a bathtub wall rail by a home health agency is E0241. This code specifically designates a grab bar or wall rail intended for use in or around a bathtub, which enhances safety for patients who may have difficulty with balance or mobility. These devices are essential for preventing falls and providing support when entering or exiting the bathtub.

E0240 refers to a grab bar that is not explicitly for bathtubs or may have different specifications, making it less appropriate for this scenario. Meanwhile, E0242 typically describes a different type of grab bar or handrail used in other settings, and E0243 relates to yet another specification that does not apply here. Hence, E0241 is distinctly the suitable choice for billing a bathtub wall rail.
