✍️ Sample CFO Questions & Answers
1. How do CFO professionals build credibility with clients?
Professional credibility is built through demonstrated competence, transparent communication, ethical conduct, and reliable delivery over time.
2. A Certificate of Medical Necessity (CMN) for orthotics must be signed by which provider?
The ordering physician must sign the CMN to certify that the orthotic device is medically necessary for the patient.
3. Which entity audits Medicare DME suppliers and can demand repayment for improperly billed orthotic claims?
Recovery Audit Contractors (RACs) are authorized by CMS to identify and recover improper Medicare payments through post-payment audits of supplier claims.
4. During normal walking, ground reaction force peaks at approximately how many times body weight?
During normal level walking, ground reaction force peaks at approximately 1.1–1.2 times body weight, occurring during loading response and terminal stance.
5. How do orthotic devices improve mobility?
Orthotic devices improve mobility by providing external support and stability to weakened or injured body parts, rather than directly increasing joint flexibility. This support helps to reduce pain, correct biomechanical imbalances, and offload stress from affected structures. By doing so, orthotics enable individuals to move more freely, confidently, and with less discomfort than they could without the device.
6. When a patient reports their orthotic has 'broken in' and feels flat after 12 months, what is the recommended clinical action?
A 'flat' orthotic indicates material fatigue and loss of corrective geometry, necessitating clinical evaluation and likely refabrication to restore function.
