✍️ Sample CMC Questions & Answers
1. Which HCPCS Level II code category covers enteral and parenteral nutrition therapy and supplies?
B codes (B4034–B9999) cover enteral and parenteral nutrition therapy products, equipment, and related supplies in HCPCS Level II.
2. How should a CMC professional handle a situation where evidence-based practice & research methods protocols conflict with practical constraints?
When protocols conflict with practical constraints, the professional approach is to document the conflict and seek guidance, ensuring transparency and compliance while working toward a resolution.
3. What type of tissue connects muscles to bones?
Tendons are strong, fibrous connective tissues that specifically attach muscles to bones. They are crucial for transmitting the force generated by muscle contractions to the bones, enabling movement. In contrast, ligaments connect bones to other bones, and cartilage provides cushioning and flexibility.
4. What is the correct sequence if both acute and chronic conditions are coded?
When both acute and chronic conditions are present and coded, the acute condition should be sequenced before the chronic condition. This sequencing rule applies when there is no specific combination code available for both. For example, acute exacerbation of chronic bronchitis would be coded with the acute condition first.
5. When implementing communication & interprofessional collaboration practices, what should a CMC professional prioritize first?
Compliance with established standards and protocols must be the first priority, as it ensures safety, quality, and legal adherence in professional practice.
6. What does the OIG do in relation to medical coding?
The Office of Inspector General (OIG) within the Department of Health and Human Services (HHS) is responsible for protecting the integrity of HHS programs, including Medicare and Medicaid. A key part of their role is to monitor and investigate healthcare fraud and abuse. They work to identify and prosecute individuals and organizations that engage in illegal activities like false claims or kickbacks.
