Authorized item and frequency: One pair of custom-molded shoes and inserts OR one pair of extra-depth shoes per calendar year; additional pairs of inserts per calendar year allowed consistent with Medicare (two additional pairs for custom-molded; three additional pairs for extra-depth)

Billing codes and modifiers: Service billed with applicable HCPCS codes in the range L3000–L3649 and any required modifiers (for example, KX when statutorily required)

Claims for shoes and related modifications, inserts, heel/sole replacements or shoe transfers billed without a KX modifier will be denied as noncovered when statutorily excluded

Payment and plan applicability: Item is payable under the Medicare Plus Blue enhanced benefit with coverage up to 100% of the approved amount when other criteria are met

Enhanced benefit may expand Original Medicare restrictions; orthotic shoe need not be attached to a leg brace for coverage under this enhanced benefit

Provider, location, diagnosis, and age conditions: Eligible provider, payable location, frequency limits, diagnosis restrictions, and age restrictions: no restrictions under Conditions for Payment table

Providers must follow Medicare Advantage PPO billing requirements and plan documentation rules

Claims for shoes, shoe modifications, inserts, heel/sole replacements, or shoe transfers that are billed without the required KX modifier will be denied as noncovered. Providers must include the KX modifier when it is statutorily required to avoid automatic denial.

This Enhanced Benefit Policy does not serve as an authorization, certification, explanation of benefits, or a contract for the services, devices, or drugs referenced. Providers must verify member coverage and follow plan-specific authorization and benefit verification processes; this policy alone is not a guarantee of payment.

Items or services that Original Medicare excludes or restricts but are listed in this document have been specifically noted where Original Medicare rules were modified or removed for the enhanced benefit. Providers should consult this policy and the member's Evidence of Coverage to determine whether an item not covered by Original Medicare is payable under the Medicare Plus Blue enhanced benefit.

Billing, Authorization, and Documentation Requirements

Billing Rule

Billing and payment basis for covered codes

Coverage for orthopedic shoes, shoe modifications, inserts, heel/sole replacements or shoe transfers follows Original Medicare rules with the Medicare Plus Blue enhanced benefit payment methodology. Medicare Plus Blue will reimburse consistent with Original Medicare allowed amounts; providers will be paid the lesser of the allowed amount or the provider's charge, minus the member's cost share. Providers must bill using Medicare Advantage PPO billing requirements and follow Medicare Advantage-specific claim submission rules. Use CMS 1500, UB-04, or the 837 equivalent; report CPT/HCPCS and diagnosis codes to the highest level of specificity and include your NPI on all claims. Electronic billing is preferred; Michigan providers may use the Blue Cross EDI resources on bcbsm.com/providers/help/edi/.

Payment basis: Reimbursement consistent with Original Medicare; paid the lesser of allowed amount or charge, minus member cost share.
Claim forms: CMS 1500 (02/12), UB-04 or 837 equivalent; follow Medicare Advantage PPO unique billing requirements.
Coding: Report CPT/HCPCS (L3000-L3649 when applicable) and diagnosis codes to highest specificity; include NPI.

Clinical and Policy Background

Orthopedic shoes and orthotic shoe inserts are devices intended to correct abnormal or irregular walking patterns by altering foot strike angles. Original Medicare Part B covers therapeutic shoes and inserts for beneficiaries with diabetes and severe diabetic foot disease and allows additional pairs of inserts under specified conditions (for example, two additional pairs for custom-molded shoes and three additional pairs for extra-depth shoes). Medicare also covers footwear and modifications when the shoe is an integral part of a covered leg brace; however, this enhanced Medicare Advantage benefit may expand coverage beyond those Original Medicare constraints and provide up to 100% of the approved amount for eligible members under the Medicare Plus Blue plan.
