A 2008 U.S. federal law requires that group health insurance plans provide comparable coverage for mental health services and medical/surgical services. This means that financial requirements (like co-pays) and treatment limitations (like the number of covered visits) for mental health care cannot be more restrictive than those for physical health care.

Analyze the following scenario: An individual's health insurance plan covers an unlimited number of physical therapy visits for post-surgery rehabilitation. However, the same plan limits coverage for outpatient psychotherapy sessions to only 20 visits per year. Based on the principle described, is this plan compliant? Explain your reasoning.
