The Sickle Cell Disease Comprehensive Care Act — and Why Arizona Can't Wait.

In the 25 years I have practiced medicine and worked at the intersection of public health and community advocacy, I have never seen the sickle cell field move this fast on this many fronts at once. Two parallel bills sit in the U.S. Congress right now — S.721 in the Senate and H.R.5178 in the House — both called the Sickle Cell Disease Comprehensive Care Act. If either becomes law, every state Medicaid program in the country would have a green light to build a coordinated SCD Health Home: care coordination, behavioral health, dental, vision, the works. It would, for the first time, treat sickle cell disease the way we have learned to treat any other complex chronic condition.

It is not law yet. But three states are not waiting. And one state — the one I now spend most of my time on — needs to stop watching.

What the federal Act actually does

The Act is, on paper, almost boring. It does not invent a new program. It does not appropriate a vast new pot of money. What it does is let states use a tool they already have — the Medicaid Health Home, a Section 2703 designation under the Affordable Care Act — and apply it specifically to people living with SCD. Today, Health Homes are scoped around conditions like serious mental illness, asthma, diabetes, and substance use disorder. The federal Act would add SCD as a single-qualifying condition, meaning a person with sickle cell disease alone would qualify for an enrolled care team without needing to also have one of the existing conditions.

That tiny change unlocks something big. A Health Home gets reimbursed for the care coordination work that determines whether someone with SCD shows up for hydroxyurea adherence visits, gets to a comprehensive SCD center, knows their pain plan, and stays out of the emergency department for the wrong reasons. It pays community health workers. It pays for the warm handoffs. It pays for the work nobody is paying for today.

Sen. Cory Booker and Sen. Tim Scott — a Democrat from New Jersey and a Republican from South Carolina — are the Senate co-leads. Reps. Neal Dunn (R-FL) and Danny Davis (D-IL) are the House co-leads. That is not an accident. SCD policy is one of the rare places in U.S. health policy where the politics actually clear. Nobody opposes care for people with SCD. The fight has always been will, not consensus.

What the states are doing now

While the federal bill works through committee, four states are already moving:

Texas's HB107 is the cleanest, most copyable model in the country right now. It is a single-purpose bill: it directs the Texas Department of State Health Services to build and maintain a sickle cell disease registry that hospitals, providers, and labs must report into. It is HIPAA-aligned. It contains the data infrastructure every other policy win is going to need — because you cannot fund what you cannot count.

New York went broader. Its 2025 legislative package layered three things: a registry, a public-facing education and mapping program, and explicit guidance that people with SCD on Medicaid can enroll in a Health Home. Effectively, New York is acting as if the federal Act has already passed, by building the state-side infrastructure now. When the federal Act does pass, New York will have a head start of years.

California took a different angle — instead of state legislation, it applied to a federal initiative on gene therapy access. California already runs the Networking California for Sickle Cell Care (NCSCC) consortium, and the CA Sickle Cell Disease Foundation just won a Pfizer SCALE grant for the SC Crew Policy Training Initiative, which trains 16-to-24-year-olds with SCD to be policy changemakers. That is a different but complementary play: build the next generation of advocates while you wait for the law.

Why Arizona has to enter the conversation now

Here is the uncomfortable truth I keep coming back to. Arizona has approximately 900 people living with sickle cell disease — modeled, because Arizona is not in CDC's SCDC surveillance program, so we don't actually know the real number. Most of them are concentrated in Phoenix and Tucson. We have one comprehensive SCD center in the entire state. There is no state SCD registry. There is no state SCD task force. There is no Medicaid Health Home option for SCD under AHCCCS. There is no statewide quality standard for emergency department care for vaso-occlusive crisis.

What does "policy follows population" sound like when the state has no idea where the population is? It sounds like silence. And silence is what we have right now in Arizona.

The Sickle Cell Foundation of Arizona — the team I am proud to work alongside — has been quietly building the infrastructure for a different answer. The 360° SCD Hub gives us a digital backbone. Our Banner Health nurse training partnership gives us a clinical wedge. What we need next is policy.

Three things SCFA is calling for in Arizona

1. The Arizona Sickle Cell Disease Registry Act

Modeled on Texas HB107, this would direct Arizona Department of Health Services to build and maintain a SCD registry. Hospitals, providers, and labs would report. The registry would feed both the state PHIT Scorecard and the federal SCDC program when AZ eventually joins. A single source of truth for the ~900 — and growing — Arizonans living with SCD.

2. AHCCCS Sickle Cell Health Home Option

Either as a stand-alone state plan amendment or in anticipation of the federal Act, AHCCCS would add SCD as a single-qualifying condition under the Medicaid Health Home program. Care coordination, community health workers, behavioral health, and pharmacy benefits all delivered as a coordinated team. New York's S.1578 is the template here.

3. The One-Hour Initiative for ED SCD Care

A quality standard requiring that Arizona emergency departments treat SCD patients triaged at Emergency Severity Index level 2 within 60 minutes of arrival. The standard already exists in national guidelines. What is missing is state-level enforcement and measurement. The 2025 Pfizer SCALE awardee Sickle Cell Medical Advocacy Inc. is doing exactly this work elsewhere. We can lead it in Arizona, starting with a Banner pilot.

What you can do this week

• If you live with SCD or care for someone who does in Arizona — join the SCFA mailing list, watch for the AZ SCD Lived Experience Survey launching this summer, and tell three people about the 360° SCD Hub.
• If you are a provider, system, or health plan in Arizona — join the Arizona Sickle Cell Comprehensive Care Coalition. We are convening it now. Banner Health, Phoenix Children's, University of Arizona Health, AHCCCS, and SCFA are the starting table.
• If you are anywhere in the country — endorse the federal Sickle Cell Disease Comprehensive Care Act with your member of Congress. Both S.721 and H.R.5178 need more co-sponsors before they move.

We will be tracking every state's progress on the new SCD Legislation Heatmap. Watch for the next post in this series — I'll walk through the One-Hour Initiative ED protocol in detail, with the actual triage criteria and a model order set you can hand your medical director.

The science is settled. The drugs work. The coordination model works. What is left is the will. Arizona, this is our moment.
