HCPCS E0118: Crutch substitute, lower leg platform, each

E0118 is generally noncovered by Medicare. Coverage is typically denied for E0118 as not reasonable and necessary; approvals are exceptional and policy-dependent.

The modifier NU (New equipment) is typically used for the purchase of DME items. The RR modifier (Rental) is used for rental claims.

The primary reason is a mobility limitation that significantly impairs the patient's ability to move within their home and is necessary because the patient cannot safely use or has documented difficulty using a standard crutch.
