Which statement correctly pairs the codes with their service types?

• A. 99605 and 99606 are MTM CPT codes; 99406 and 99407 are Smoking Cessation CPT codes
• B. 99406 and 99407 are MTM CPT codes; 99605 and 99606 are Smoking Cessation CPT codes
• C. 99406 and 99407 are ICD codes
• D. 99605 and 99606 are ICD codes

Answer: (A)

These codes distinguish the type of professional service being billed. Medication Therapy Management (MTM) codes are the CPT codes 99605 and 99606, used to bill MTM services provided by clinicians such as pharmacists to optimize a patient’s medications. The tobacco use cessation codes are 99406 and 99407, used for counseling to help a patient quit smoking, with different time lengths for the sessions. So the pairing that assigns MTM codes to MTM services and smoking-cessation codes to smoking-cessation counseling is correct. The other options mix up the service types or mislabel these as ICD codes, which are diagnostic codes rather than CPT codes for professional services.
