Evidence and guideline-informed coverage considerations
From Hawke et al. Cochrane review; VHA guideline progression referenced
Before age three, children normally have flat feet and the medial arch does not typically begin to develop until about age three. Therefore, flexible flat feet in children younger than three years that are asymptomatic are implied non‑indications for foot orthotics and are not considered medically necessary when there is no foot pain or functional impairment.
Over‑the‑counter (OTC) orthotic inserts are excluded from coverage under any circumstance and are ineligible for reimbursement. In addition, foot orthotics are not covered for common non‑specific or cosmetic conditions including corns, calluses, hammertoes, flat feet (when not symptomatic), pronation, fallen arches, weak feet, chronic foot strain, or other symptomatic complaints of the feet that do not meet the medical necessity criteria.
Evidence for benefit of custom‑made foot orthoses varies by condition. A Cochrane review (Hawke et al., 2008) found clear benefit for some diagnoses (e.g., painful pes cavus) but noted that it is unclear whether custom‑made orthoses are effective for plantar fasciitis or for metatarsophalangeal joint pain in rheumatoid arthritis. The review concluded that overall evidence is limited and condition‑specific when informing orthotic prescription.
Orthotics should not be used as first‑line therapy. Before prescribing foot orthoses, documentation must show the member has failed an appropriate course of conservative treatments (for example, physical therapy, injections, strapping, or anti‑inflammatory medications). Only after conservative measures have been attempted and documented should orthotics be considered.
Only one orthotic per foot is considered medically necessary; duplicate orthotics or separate orthotics for each pair of shoes are not medically necessary and are considered a matter of convenience. Foot orthotics are also not medically necessary when the underlying foot condition does not cause symptoms.
Coverage and prior authorization requirements are product and contract dependent. If a Medicare HMO‑DSNP product covers the service and there is no applicable national or local Medicare coverage decision, the medical policy criteria apply; if a Medicare HMO‑DSNP product does not cover a service, follow the Medicaid product coverage line per the product rules. Verify the member's product benefit and prior authorization requirements before delivering or billing orthotics.

Provider Actions, Documentation, and Prior Authorization
One orthotic per foot limit
Only one (1) orthotic per foot is considered medically necessary; prior authorization may be required per plan rules.
Verify contract and obtain prior authorization
Coverage for foot orthotics is contract dependent; verify member benefits and obtain prior authorization when the orthotic is claimed under medical benefits for exceptions (e.g., insert integral to a leg brace or rehabilitative orthotics dispensed at time of surgery/casting).
Prior authorization tied to product coverage
Prior authorization requirements follow the member's product benefit: if the product covers the service, medical policy criteria apply; if the product does not cover the service, policy criteria do not apply.
Conservative therapy required before orthotics
Orthotics should not be considered first-line therapy; document failure to respond to an appropriate course of conservative treatment (e.g., physical therapy, injections, strapping, anti-inflammatory medications) before requesting orthotics.
Limit on number and OTC exclusion
Only one orthotic per foot is allowed and over-the-counter (OTC) orthotics are ineligible for coverage under any circumstance.
Therapeutic progression (OTC → custom)
VHA footwear guidance describes a therapeutic progression of footwear and orthotic insert options based on pathology severity (for example, OTC accommodation orthoses progressing to semi-rigid or rigid functional orthoses or custom molded devices).
Required documentation to support medical necessity
Documentation must demonstrate the patient has symptoms related to the foot condition, has failed an appropriate course of conservative treatment, and that no more than one orthotic per foot is being requested.
Confirm non‑OTC status and note contract exceptions
Document that the device is not an over-the-counter insert and, when applicable, document contract-specific exceptions such as when a shoe insert is integral to a leg brace or rehabilitative orthotics are dispensed at the time of surgery/casting.
Use listed HCPCS and diagnosis codes on claims
Use the HCPCS L3000–L3090 series and S0395 as listed in the policy for orthoses and impression casting; include appropriate ICD‑10 diagnosis coding on claims.
- HCPCS orthosis codes: L3000–L3090
- Impression casting: S0395
- Include relevant ICD‑10 diagnosis codes
Denial risk: missing symptoms or conservative therapy
Lack of documented symptoms related to the foot condition or failure to document prior appropriate conservative treatment (e.g., physical therapy, injections, strapping, anti‑inflammatory medications) may trigger denial.
Denial risk: duplicates and non‑covered indications
Duplicate orthotics (more than one device per body part for the same function) and orthotics prescribed for noncovered indications such as corns, calluses, hammertoes, asymptomatic flat feet, pronation or other listed non‑indications are not medically necessary and may be denied.
Contract-dependent coverage may result in denial
Services are contract dependent; if a member's product does not cover a specific service, medical policy criteria do not apply and a coverage denial may be appropriate per product rules.
Background and Evidence Summary
Foot orthotics are mechanical devices placed in a shoe to restore or maintain foot alignment and to relieve stress on foot structures. They may be soft, semi‑rigid, or rigid and can be custom‑made or prefabricated. This policy distinguishes orthotics from other devices (for example, orthopedic footwear) and sets condition‑specific criteria for when orthoses are medically appropriate to treat symptomatic foot conditions.
A systematic review (Hawke et al., 2008) included 11 trials with 1,332 participants and found that custom‑made foot orthoses were effective for certain conditions (e.g., painful pes cavus, rearfoot pain in rheumatoid arthritis, foot pain in juvenile idiopathic arthritis, and painful hallux valgus) but that evidence was limited overall. The review specifically noted it is unclear whether custom orthoses are effective for plantar fasciitis and for metatarsophalangeal joint pain in rheumatoid arthritis, and concluded that limited evidence exists to guide orthoses prescription for many foot pain conditions.
