Benign Prostatic Hyperplasia (Investigational Adjunct)
Tier CInvestigational adjunct for symptomatic benign prostatic hyperplasia; alpha-blockers, 5-alpha-reductase inhibitors, and minimally invasive surgical therapy remain evidence-based.

Tier CPalliative investigational adjunct for endometrioma-related chronic pelvic pain in patients declining or unable to undergo surgical/hormonal management.
Adenomyosis (Investigational Palliative Adjunct)
Tier CInvestigational palliative adjunct for adenomyosis-related dysmenorrhea and pelvic pain; hormonal therapy (LNG-IUD, dienogest, GnRH antagonists) and (definitively) hysterectomy remain evidence-based.
Chronic Refractory Tinnitus (Investigational Adjunct)
Tier CInvestigational adjunct for chronic refractory subjective tinnitus; cognitive behavioral therapy, sound therapy, and hearing aids for concurrent hearing loss remain evidence-based.
Chronic Non-Allergic Rhinitis (Investigational Adjunct)
Tier CInvestigational adjunct for chronic non-allergic rhinitis; intranasal corticosteroids, intranasal antihistamines, and trigger avoidance remain evidence-based.
Ankylosing Spondylitis Axial Pain (Investigational Adjunct)
Tier CInvestigational adjunct for axial pain in ankylosing spondylitis; NSAIDs, biologic DMARDs (TNF and IL-17 inhibitors), and structured exercise remain evidence-based first-line therapy.
Burning Mouth Syndrome (Investigational Adjunct)
Tier CInvestigational adjunct for primary burning mouth syndrome; clonazepam (topical or systemic), alpha-lipoic acid, low-dose tricyclics, and cognitive behavioral therapy remain evidence-based.
