Q1: A patient with diabetes presents with peripheral neuropathy, a prior history of plantar ulceration
at the first metatarsal head, and a hammertoe deformity on the right foot. Which Medicare HCPCS
code category is used for the therapeutic shoe inserts prescribed for this patient?
A. L3000-L3649 for custom-molded foot orthoses
B. A5503-A5513 for diabetic therapeutic shoe inserts
C. L3216-L3222 for depth-inlay shoes only
D. A5503-A5513 for diabetic therapeutic shoe inserts [CORRECT]
Correct Answer: D
Rationale: Correct because Medicare's Therapeutic Shoes for Persons with Diabetes benefit uses
A-codes (A5503-A5513) for inserts and modifications related to diabetic shoes (A5500-A5501),
while L-codes (L3000-L3649) are used for non-diabetic orthotic footwear and general foot
orthoses.
,Q2: During a biomechanical examination, the orthotic fitter observes that the patient's calcaneus
remains in valgus when the subtalar joint is placed in neutral position. This finding indicates which
forefoot-to-hindfoot relationship?
A. Forefoot varus with compensated rearfoot valgus
B. Forefoot valgus with uncompensated rearfoot varus
C. Forefoot varus with uncompensated rearfoot valgus [CORRECT]
D. Forefoot valgus with compensated rearfoot valgus
Correct Answer: C
Rationale: Correct because when the calcaneus remains in valgus in subtalar neutral, this
represents an uncompensated rearfoot valgus; the forefoot varus is the structural deformity
requiring orthotic correction with medial posting.
Q3: Which tarsal bone articulates with the talus superiorly, the calcaneus inferiorly, and the
navicular anteriorly to form the talonavicular portion of the Chopart joint?
A. Cuboid
B. Cuneiform
C. Talus [CORRECT]
,D. Navicular
Correct Answer: C
Rationale: Correct because the talus is the keystone of the ankle mortise and subtalar complex; it
articulates with the tibia/fibula superiorly, calcaneus inferiorly at the subtalar joint, and navicular
anteriorly at the talonavicular joint.
Q4: A patient with plantar fasciitis reports morning first-step pain localized to the medial calcaneal
tubercle. Radiographs reveal a heel spur. What is the relationship between the heel spur and the
patient's symptoms?
A. The heel spur is the primary cause of plantar fasciitis pain
B. The heel spur is associated with but not causative of plantar fasciitis symptoms [CORRECT]
C. The heel spur indicates the need for surgical excision
D. The heel spur confirms calcaneal stress fracture
Correct Answer: B
Rationale: Correct because heel spurs are radiographic findings associated with chronic plantar
fascial traction but are not the causative factor; symptoms derive from microtears and inflammation
at the plantar fascia insertion on the medial calcaneal tubercle.
, Q5: In the windlass mechanism of the plantar fascia, dorsiflexion of the great toe during late stance
phase produces which biomechanical effect?
A. Eversion of the calcaneus and flattening of the medial longitudinal arch
B. Elevation of the medial longitudinal arch and external rotation of the leg [CORRECT]
C. Plantarflexion of the first ray and unlocking of the midtarsal joint
D. Adduction of the forefoot and inversion of the subtalar joint
Correct Answer: B
Rationale: Correct because dorsiflexion of the hallux tightens the plantar aponeurosis, raising the
medial longitudinal arch and creating a rigid lever for propulsion while externally rotating the tibia;
this is the active windlass mechanism.
Q6: Which HCPCS Level II code describes a foot insert that is removable, molded to patient model,
with longitudinal and metatarsal support?
A. L3000
B. L3020 [CORRECT]
C. L3040
D. L3060
Correct Answer: B
