Massachusetts statute and program

The Massachusetts Medical Use of Marijuana Program is the operating authority for Massachusetts patient certification. The authoritative legal text is: M.G.L. Chapter 94G: Regulation of the Use and Distribution of Marijuana Not Medically Prescribed. The program portal is at Massachusetts Medical Use of Marijuana Program.

What the evidence says about cannabis and Complex Regional Pain Syndrome

CRPS Type I follows soft-tissue injury, fracture, or surgery without identifiable nerve injury. CRPS Type II follows confirmed peripheral nerve injury. Diagnosis is clinical, based on the Budapest Criteria (International Association for the Study of Pain), which require disproportionate pain plus signs and symptoms across multiple of four categories (sensory, vasomotor, sudomotor/edema, motor/trophic).

For the full evidence base, including the NASEM tier, randomized trial summaries, and symptom-domain breakdown, read the mmjnow Complex Regional Pain Syndrome page.

How to qualify in Massachusetts

The Massachusetts Medical Use of Marijuana Program requires the following registration steps for a Complex Regional Pain Syndrome patient (or any qualifying diagnosis):

  1. Get certified by a Massachusetts-licensed certifying healthcare provider. A Massachusetts-licensed physician, certified nurse practitioner, or physician assistant registered with the Cannabis Control Commission (CCC) Medical Use of Marijuana Program must establish a bona-fide provider-patient relationship and certify a debilitating condition. CCC regulations allow providers to certify enumerated conditions (cancer, glaucoma, HIV/AIDS, hepatitis C, ALS, Crohn’s, Parkinson’s, MS) plus "other conditions determined by a qualifying provider" — broad practitioner discretion.
  2. Complete the online patient registration via Virtual Gateway. After certification, the provider creates a Virtual Gateway PIN that the patient uses to complete the online registration through the Massachusetts Cannabis Control Commission MMJ Online System. Patients upload a Massachusetts driver license or state ID and a passport-style photo.
  3. Pay the $50 state fee (or qualify for fee waiver). The annual program registration fee is $50, waived for veterans, low-income patients (verified through MassHealth, SNAP, SSI, SSDI, or Veterans Affairs benefits documentation), and hospice patients. Temporary patient registration cards are emailed within several business days of approval; physical cards arrive within roughly two to three weeks.
  4. Purchase from a Massachusetts medical marijuana treatment center. With the temporary or physical card, patients may purchase up to a 60-day supply (default 10 ounces) from any of the licensed Massachusetts Medical Marijuana Treatment Centers. Adult-use retail exists statewide for adults 21+, but the medical registration provides access to medical-only products, no excise tax, higher possession limits, and family-court and workplace protections under M.G.L. c. 94I.

ICD-10 code

A certifying physician documenting Complex Regional Pain Syndrome for the Massachusetts medical cannabis program will typically record ICD-10 G90.50 or SNOMED-CT 128200000 in the patient's record. The state registry does not itself collect ICD-10 codes in most programs, but the physician's chart is the audit trail if the certification is later reviewed.

Frequently asked questions

Does Massachusetts list Complex Regional Pain Syndrome as a qualifying condition for medical cannabis?

Not by name, but Massachusetts permits physician discretion. Under Massachusetts Medical Use of Marijuana Program, a certifying physician can add a condition like Complex Regional Pain Syndrome on a case-by-case basis when the physician judges that the patient would benefit from medical cannabis. This is different from a state where the qualifying-condition list is fixed in statute. Whether a particular physician will certify Complex Regional Pain Syndrome depends on the physician's training, the strength of the patient's documentation, and the practitioner's reading of the available evidence — evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). Patients should expect to bring full diagnostic records to the certification visit.

How do I get a Massachusetts medical marijuana card for Complex Regional Pain Syndrome?

Step one is finding a physician licensed in Massachusetts who is registered with Massachusetts Medical Use of Marijuana Program and willing to evaluate Complex Regional Pain Syndrome cases. Step two is collecting your records (diagnosis documentation, treatment history, and the ICD-10 code your physician will use) and bringing them to the certification visit. Step three is the physician's certification through the state registry, followed by the patient registration application, state fee, and waiting period before the card is issued. Massachusetts does not honor out-of-state cards, so the certification process has to originate inside the state. Verify the patient minimum age with the state program before applying. The authoritative source for the current process is the Massachusetts Medical Use of Marijuana Program site at https://masscannabiscontrol.com/medical-use/; the state updates fees, forms, and physician registration rules periodically.

What does the evidence say about cannabis for Complex Regional Pain Syndrome?

For Complex Regional Pain Syndrome, evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). The mmjnow condition page for Complex Regional Pain Syndrome lays out the current evidence base, including the citations underlying that evidence tier — typically the National Academies of Sciences, Engineering, and Medicine consensus reports, federal agency guidance, and peer-reviewed reviews. Evidence quality is independent of state law: a state can list a condition for which evidence is limited, and a state can decline to list a condition for which evidence is strong. Patients deciding whether to pursue medical cannabis for Complex Regional Pain Syndrome should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Complex Regional Pain Syndrome and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Complex Regional Pain Syndrome; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
