Medical Occupations - As enacted, changes references to marital and family therapists to marriage and family therapists throughout the code, and makes other changes relative to marriage and family therapists. - Amends TCA Title 4, Chapter 29; Title 8, Chapter 50; Title 33; Title 36; Title 52; Title 56; Title 63 and Title 68.

HB 1909 updates Tennessee's legal terminology by changing all references from "marital and family therapists" to "marriage and family therapists" across multiple state code sections (including licensing, practice standards, and definitions in Titles 4, 8, 33, 36, 52, 56, 63, and 68). This primarily affects licensed therapists, state licensing boards, and healthcare facilities by standardizing professional titles and aligning with common industry terminology. Key provisions include revising licensing reciprocity rules (Section 16) and clarifying practice boundaries for therapists (Section 20), ensuring consistency in how the profession is referenced in law. The bill makes no substantive policy changes beyond terminology adjustments and does not alter therapist qualifications or patient protections.
