Which payers commonly require documentation of visit duration?

• A. Private insurers
• B. Self-pay patients
• C. Medicare and Medicaid
• D. Worker's compensation

Answer: (C)

Time spent with the patient is often the basis for selecting the level of service in many billing systems, and Medicare and Medicaid place a particular emphasis on documenting that visit duration. In these programs, the medical record should reflect the total time spent on the encounter—including counseling, coordination of care, and related activities on the date of service—so the coder can justify the chosen code and ensure appropriate reimbursement. While other payers may also consider time in some cases, they do not universally require explicit duration documentation in the same way Medicare and Medicaid do. Self-pay has no payer-specific duration requirements, and workers’ compensation follows its own rules, which may focus more on treatment parameters or impairment considerations rather than time alone.
