Opening or expanding a TMS clinic looks straightforward on paper: steady demand, proven clinical outcomes, and a procedure that genuinely helps people who’ve run out of options. But the moment reimbursements start lagging, reality hits. Cash flow gets tight, staff hours balloon with rework, and suddenly the clinic’s growth feels less like a clean upward line and more like a stubborn climb. Much of this strain traces back to billing that wasn’t built for the nuances of neuromodulation. That’s where a specialized TMS Billing Company makes all the difference.

At Finnastra, we regularly hear from new clinics surprised by how temperamental TMS coverage can be. A claim might look perfect until an insurer notices a missing severity score or questions the sequencing of sessions. One clinic told us they spent almost a month reprocessing claims because a single modifier was off. It’s not carelessness; TMS billing is simply its own ecosystem.
A seasoned TMS Billing Company steps in early, setting up coding pathways tailored to each payer. CPT codes like 90867 or 90868 aren’t complex by themselves; it’s the rules wrapped around them that trip clinics up. We map out those rules, anticipate payer requests, and make sure every claim lands cleanly the first time. Clinics see the impact almost immediately: fewer back-and-forth emails, fewer resubmissions, and a steadier rhythm of reimbursements.
Growth brings its own chaos. As patient volume rises, even the most organized team can miss a PHQ-9 update or forget to note a previous medication trial. Insurer’s notice. And TMS claims, unlike routine psychiatry visits, doesn’t tolerate gaps.
Finnastra builds guardrails around this. We review charts with an eye for clinical detail, the same way an auditor would. If something feels incomplete, we flag it before the claim goes out. It’s a quiet kind of work, not glamorous, but it prevents the kind of denials that can drain a clinic’s monthly revenue. This is where a TMS Billing Company earns its keep: by catching the small things before they snowball.
Anyone running a TMS program knows how disruptive prior authorization delays can be. A patient is ready to start treatment, the schedule is blocked off, and then, nothing. The insurer needs “one more document,” or the clinical reviewer has a question that takes a week to resolve.
We take that entire process off the clinic’s plate. Our team handles submissions, writes clinical summaries, follows up with reviewers, and pushes for timely approvals. Because a TMS Billing Company that understands the therapy understands how time-sensitive these authorizations are. When PAs move smoothly, treatment plans stay on track, and cash flow follows that rhythm.
Revenue doesn’t stop with clean claims. What occurs following submission frequently decides if a clinic does well or is always behind. We keep a tight eye on aging buckets, appeal underpayments, and fight denials with detailed, evidence-based reasons. The purpose isn’t only to collect money; it’s also to make sure that clinics get the money they have rightfully earned.
Finnastra also shares detailed performance data with partners. Not fluffy dashboards, actual patterns, payer behavior, bottlenecks. With that clarity, clinics can make decisions based on real trends, not guesswork. It’s one of the practical ways a TMS Billing Company keeps financial momentum steady, especially for practices in the middle of rapid expansion.
Clinics often come to us after trying to juggle billing internally and realizing the downstream impact on cash flow and staff workload. Neuromodulation deserves its own billing strategy, and we’ve refined ours over years of working alongside providers who want both accuracy and long-term stability. And for clinics branching into related services, weight management, metabolic programs, or multidisciplinary care, we also handle Bariatric Billing Services, giving practices the option to centralize everything under one team.
If your clinic is growing, or you want it to, your revenue systems need to keep pace. Let Finnastra take over the billing complexities while you focus on clinical work that actually moves patients forward.
