Ketamine Providers in Colorado

Ketamine Therapy in Colorado

Colorado is home to 78 ketamine therapy providers offering IV infusions, Spravato nasal spray, and sublingual treatments for depression, anxiety, and PTSD. As one of the nation's most progressive states for psychedelic-assisted therapy — bolstered by Proposition 122's legalization of psilocybin healing centers — Colorado offers a uniquely supportive environment for innovative mental health treatments. From Denver and Boulder to Colorado Springs and mountain communities, providers across the state are expanding access to this rapid-acting therapy.

Colorado ranks 5th nationally with 69 ketamine therapy providers, averaging 3.1 providers per city. The largest provider category is psychiatry practice (37.7% of providers). Denver leads the state with 18 providers. 2 providers offer telehealth services.

State Regulations

Colorado classifies ketamine as a Schedule III controlled substance, legal for off-label therapeutic use when prescribed by licensed, DEA-registered providers. While Proposition 122 (Natural Medicine Health Act, 2022) legalized psilocybin therapy at licensed healing centers, it does not directly cover ketamine. However, Prop 122 reflects Colorado's progressive stance on psychedelic-assisted therapy, creating a cultural and regulatory environment where ketamine clinics thrive.

Insurance & Medicaid Coverage

Colorado Medicaid (Health First Colorado) generally covers Spravato (esketamine) nasal spray for eligible patients with treatment-resistant depression. Coverage requires prior authorization to document treatment history, including failed trials of adequate antidepressant therapies. Spravato must be administered at a REMS-certified healthcare facility. Standard IV ketamine infusions remain an out-of-pocket expense not covered by Medicaid.

Telehealth Options

Colorado permits ketamine prescribing via telehealth under DEA telemedicine flexibilities extended through December 31, 2026. Providers must hold active Colorado medical licenses and DEA registration. Colorado law broadly supports telehealth parity, prohibiting insurers from imposing telehealth-specific limitations. Multiple Colorado clinics offer sublingual ketamine with virtual monitoring.

Cost of Ketamine Therapy

IV ketamine infusions in Colorado typically cost $400–$800 per session. Denver and Boulder metro clinics typically charge $450-$600 per infusion, while providers in Colorado Springs and smaller cities may offer rates starting at $400. A standard initial series of 6 infusions runs $2400–$4800. Spravato (esketamine) may be partially or fully covered by insurance.

Mental Health Access

Colorado has 116 mental health HPSA designations covering nearly 950,000 underserved residents. Roughly 54 of the state's 64 counties fall within geographic mental health shortage areas, and 22 rural counties lack any psychologist or psychiatrist, making access to ketamine therapy especially limited outside the Front Range. Colorado has approximately 1.35 ketamine providers per 100,000 residents.
