A coalition of patients and healthcare providers is launching an effort to expand insurance coverage for ketamine, a non-opioid anesthetic increasingly used to treat chronic pain, depression and post-traumatic stress disorder (PTSD).

Ketamine is typically administered by infusion under strict medical supervision, a process that that can take up to an hour and cost thousands of dollars. The first goal of the Ketamine Taskforce is to get ketamine infusions fully covered by Medicare.

“Medicare doesn’t officially pay for ketamine infusions. What they will pay for is a generic infusion code similar to if someone was getting an antibiotic infused. The level of reimbursement is very low,” says Kimberley Juroviesky, a retired nurse practitioner and task force co-chair who receives ketamine infusions for Complex Regional Pain Syndrome (CRPS). 

“Since these reimbursement rates are so low, the majority of small ketamine clinics don’t accept insurance. This leaves the majority of pain patients without the pain relief they could otherwise be benefiting from.”

Ketamine is approved by the Food and Drug Administration as a surgical anesthetic, but a growing number of ketamine clinics provide off-label infusions for depression, PTSD and difficult chronic pain conditions such as CRPS. The infusions put patients into a hypnotic, dream-like state — leaving them with less physical and emotional pain once the ketamine wears off. Many insurers consider this off-label use experimental.

“If we could get Medicare to officially put ketamine on their schedule as a treatment for chronic pain, this would hopefully raise reimbursement rates to a level where all providers could afford it. Also, this would force private insurers to pay for ketamine infusions as well and no longer refuse to pay saying it’s experimental,” Juroviesky said in an email. 

PNN columnists Barby Ingle and Madora Pennington have both had ketamine infusions, Barby for CRPS and Madora while recovering from foot surgery.

“The swelling in my foot dramatically improved. Chronic, low-grade discomfort along my spine also disappeared. I felt emotional relief from past trauma, from pain and other life experiences,” Madora explained.

“I went into the hospital in a wheelchair, but walked out on my own a week later,” said Barby, after seven days of ketamine infusions. She now gets “booster” infusions four times a year and no longer takes daily pain medication.

Some ketamine users report lingering side effects, such as hallucinations and visual disturbances. Guidelines from the American Society of Anesthesiologists, American Society of Regional Anesthesia and Pain Medicine, and the American Academy of Pain Medicine only support ketamine infusions for CRPS and short-term acute pain.

“Excluding CRPS, there was no evidence supporting ketamine infusions for intermediate or long-term improvements in pain," the guidelines warn.

The Ketamine Taskforce is working with a consortium of ketamine clinics, collecting data on the safety and efficacy of infusions. That research will be shared with the Centers for Medicare and Medicaid Services (CMS) in an effort to expand Medicare coverage of ketamine for pain and mental health conditions.
