Toe Fillers and Diabetic Shoe Inserts - Coding Clarification

Questions have arisen about the correct coding for shoe inserts used to accommodate missing digits (toes) on feet for beneficiaries with and without diabetes. These items fall under two separate benefit categories and use two distinct Healthcare Common Procedure Coding System (HCPCS) codes, L5000 and A5513.

Beneficiaries without Diabetes

Shoe inserts for beneficiaries with missing toes or partial foot amputations who are not diabetic are considered for coverage under the prosthetic benefit. Code L5000 is described by:

L5000 - PARTIAL FOOT, SHOE INSERT WITH LONGITUDINAL ARCH, TOE FILLER

As noted in the descriptor, code L5000 describes a shoe insert with a rigid longitudinal arch support that also incorporates material accommodating the void left by the missing digit(s) or forefoot. Additional soft material is added where contact is made with the residual limb/toes. For beneficiaries missing digits, particularly the hallux (great toe), or the forefoot, L5000 inserts are designed to provide standing balance and toe off support for improved gait. The biomechanical control required of L5000 differs from the foot-protective function provided by inserts used as part of diabetes management.

For beneficiaries who are non-diabetic and require accommodation of missing foot digit(s) or forefoot, suppliers must only bill code L5000. Codes A5512 and A5513 describe inserts used with therapeutic shoes provided to persons with diabetes (see below) and must not be billed for non-diabetic beneficiaries.

Beneficiaries with Diabetes

A separate benefit category allows Medicare coverage of therapeutic shoes and inserts for persons with diabetes. Shoe inserts for persons with diabetes are described by the codes below:

A5512 - FOR DIABETICS ONLY, MULTIPLE DENSITY INSERT, DIRECT FORMED, MOLDED TO FOOT AFTER EXTERNAL HEAT SOURCE OF 230 DEGREES FAHRENHEIT OR HIGHER, TOTAL CONTACT WITH PATIENT'S FOOT, INCLUDING ARCH, BASE LAYER MINIMUM OF 1/4 INCH MATERIAL OF SHORE A 35 DUROMETER OR 3/16 INCH MATERIAL OF SHORE A 40 DUROMETER (OR HIGHER), PREFABRICATED, EACH

A5513 - FOR DIABETICS ONLY, MULTIPLE DENSITY INSERT, CUSTOM MOLDED FROM MODEL OF PATIENT'S FOOT, TOTAL CONTACT WITH PATIENT'S FOOT, INCLUDING ARCH, BASE LAYER MINIMUM OF 3/16 INCH MATERIAL OF SHORE A 35 DUROMETER OR HIGHER), INCLUDES ARCH FILLER AND OTHER SHAPING MATERIAL, CUSTOM
FABRICATED, EACH

For a beneficiary with diabetes missing digit(s) or a forefoot, suppliers have two options for billing inserts:

Option 1: For diabetic beneficiaries who do not require the rigidity and support afforded by code L5000 (e.g., beneficiaries missing digits excluding the hallux), suppliers must bill code A5513 for an insert appropriately custom-fabricated to accommodate the missing digit(s). Codes L5000 or A5512 may not be billed in addition to code A5513.

Option 2: For beneficiaries missing the hallux or a forefoot that require rigidity and support for effective gait, suppliers must bill L5000 for an insert appropriately custom-fabricated to accommodate the missing digit(s) or forefoot as well as providing the foot-protective functions required for a person with diabetes. Codes A5512 or A5513 may not be billed in addition to code L5000.

Suppliers are encouraged to review both the Therapeutic Shoes for Persons with Diabetes Local Coverage Determination and related Policy Article and the Lower Limb Prostheses Local Coverage Determination and related Policy Article at http://www.cms.gov/medicare-coverage-database/overview-and-quick-search.aspxExternal Websitefor additional information on the coverage, coding and documentation of these items.
