Question 1

Which insole material is most appropriate for a diabetic patient with plantar calluses?

Accepted Answer

Viscoelastic/PPT foam

Answer

Viscoelastic materials like PPT absorb shock and reduce shear forces, protecting insensate diabetic feet from callus formation and skin breakdown.

Question 2

What condition must a physician certify to qualify a patient for Medicare therapeutic shoes?

Accepted Answer

Diabetes mellitus with at least one qualifying lower limb condition

Answer

Medicare requires physician certification that the patient has diabetes mellitus with at least one qualifying foot condition such as neuropathy, ulceration, or Charcot foot.

Question 3

A rocker-bottom shoe modification is used primarily to:

Accepted Answer

Reduce pressure on the metatarsal heads and forefoot during propulsion

Answer

Rocker-bottom soles roll the foot through gait, reducing peak pressure at the metatarsal heads and decreasing the need for toe extension at push-off.

Question 4

Which situation is a contraindication for placing a standard metatarsal pad?

Accepted Answer

Active plantar ulcer directly beneath a metatarsal head

Answer

Placing a metatarsal pad over an active ulcer increases pressure at that site and worsens the wound; total contact offloading is required instead.

Question 5

What does 'DMEPOS' stand for in relation to therapeutic footwear reimbursement?

Accepted Answer

Durable Medical Equipment, Prosthetics, Orthotics, and Supplies

Answer

DMEPOS is the Medicare billing category that includes therapeutic footwear, prosthetics, orthotics, and other durable supplies.
