Why This Landed on My Radar
I just read about North Carolina’s hub-and-spoke model for integrating addiction treatment into primary care, and immediately thought about how many of our Texas colleagues are leaving both revenue and desperately underserved patients on the table. We’re trained to manage chronic diseases - hypertension, diabetes, COPD - but most of us got maybe a lecture or two on substance use disorder in med school, if that. Meanwhile, opioid use disorder is crushing rural Texas communities, and the reimbursement for medications for opioid use disorder (MOUD) is actually solid when you know how to bill it.
Here’s What’s Going On
North Carolina has built a statewide network called NC STAR that uses a hub-and-spoke model to help primary care practices integrate MOUD into routine care. The “hubs” are larger academic centers or specialist addiction programs that provide training, consultation support, and backup for complex cases. The “spokes” are primary care clinics - FQHCs, private practices, health departments - that actually deliver the treatment where patients live.
Dr. Holly Warren, who now serves as medical director of Lenoir County Health Department, admitted she got virtually no addiction medicine training two decades ago at East Carolina and Duke. Like most of us, “we just really didn’t talk about addiction medicine very much.” But she started offering MOUD at a rural FQHC in Greene County and discovered what many primary care docs are learning: this is bread-and-butter chronic disease management, just with a different medication. The North Carolina model explicitly positions primary care as the right setting because, as their philosophy states, “Any door should be the right door when somebody wants treatment.”
The hub-and-spoke approach works because it removes the two biggest barriers for primary care: knowledge gaps and fear of complexity. When you have a hub you can call for curbside consults, you’re not alone managing these patients. And the “spokes” deliver care in primary care settings where patients are already coming for diabetes checks and blood pressure management - dramatically reducing the stigma and access barriers of specialty addiction clinics.
What This Means for Your Practice
Here’s the Texas reality: we have massive opioid use disorder prevalence, particularly in rural areas and smaller cities where specialty addiction services are scarce or nonexistent. Without Medicaid expansion, many of these patients cycle through our EDs and urgent cares with complications, run up uncompensated care costs, or simply don’t get treatment at all. But the ones who do have coverage - Medicare, managed Medicaid (STAR, STAR+PLUS), many commercial plans, and increasingly Medicare Advantage - have decent MOUD reimbursement, especially when you layer in the chronic care management codes, behavioral health integration billing, and care coordination that these complex patients qualify for.
The revenue model is real. Buprenorphine induction and management visits bill at E/M levels appropriate to complexity (often 99214-99215). Monthly maintenance visits, urine drug screens, behavioral health assessments, and care coordination all generate legitimate revenue. For practices with sufficient volume, you can add CCM (99490), behavioral health integration (99484), and even psychiatric collaborative care (99492-99494) if you build the right team structure. In V28 risk adjustment, substance use disorder HCCs carry meaningful weight - accurate diagnosis coding improves your MA contract performance.
But most Texas practices aren’t doing this. Why? Same reason Dr. Warren cited: we didn’t learn it in training, we’re nervous about DEA scrutiny, we worry about “those patients” disrupting our practice, and we don’t know where to start. Meanwhile, patients who would be incredibly loyal - people whose lives you’re literally saving - go untreated or drive two hours to the nearest methadone clinic.
What Texas lacks is the infrastructure North Carolina built. We don’t have a statewide hub-and-spoke network offering training, consultation, and peer support. But the model is replicable. University of Texas health systems, the TMA, regional AHEC programs, and even some forward-thinking IPAs could create hub resources. The X-waiver requirement for buprenorphine was eliminated in 2023, so any DEA-licensed physician can prescribe it now. The barrier isn’t regulatory anymore - it’s knowledge and confidence.
Key Takeaways
- MOUD is chronic disease management - if you can manage diabetes and hypertension, you have the clinical skills to manage buprenorphine maintenance
- Reimbursement is solid when you code correctly: E/M visits, UDS, care coordination, CCM, BHI, and proper HCC capture for risk-adjusted MA contracts
- The X-waiver is gone - as of 2023, any DEA-licensed provider can prescribe buprenorphine without additional certification
- Hub-and-spoke models work by pairing primary care “spokes” with specialist “hub” support for training and complex case consultation
- Patient loyalty and retention are extraordinary - you’re treating a life-threatening chronic disease, and patients remember who was there for them
What Smart Practices Are Doing
The savviest independent docs I know are starting small: getting Project ECHO training or PCSS-MOUD certification (free online), inducting one or two stable patients, and building confidence before scaling. Some are partnering informally with addiction medicine specialists for curbside consults, essentially creating their own mini hub-and-spoke. A few are exploring tech platforms that offer virtual specialist backup and decision support, turning the “hub” into a telemedicine resource rather than a physical site.
