20 Miss. Code R. § 2-X
Codes 99304-99318 are used to report evaluation and management services to patients in nursing facilities (skilled nursing facilities (SNFs)) intermediate care facilities (ICFs), or long-term care facilities (LTCFs).
These codes should also be used to report evaluation and management services provided to a patient in a psychiatric residential treatment center (a facility or a distinct part of a facility for psychiatric care, which provides a 24-hour therapeutically planned and professionally staffed group living and learning environment). If procedures such as a medical psychotherapy are provided in addition to evaluation and management services, these should be reported in addition to the evaluation and management services provided.
