The vehicle matters less than you think, but your billing setup will make or break you
I started my mobile PT practice out of a 2012 Ford Transit Connect with a $600 plinth table I found on Facebook Marketplace. The van smelled like old gym towels for three weeks. What actually determined whether I survived the first year wasn't the vehicle or the equipment rack in the back — it was whether I understood payer mix before I spent a single dollar on marketing. Most people skip that step. They get a clinic license, buy some resistance bands, and start driving around wondering why their bank account isn't moving. Start by figuring out which insurance panels you can actually get credentialed with in your state. This is the part nobody talks about until they've been waiting eight months for Anthem to respond to their application. Credentialing takes between 90 and 180 days on average. If you can't start seeing patients while that happens, you need savings that cover at least six months of expenses. I had $12,000 set aside. It lasted 4 months and 12 days. I took a locum tenens shift at a nursing facility during the gap. Don't romanticize the independence if you haven't run the cash flow numbers first. State licensing is straightforward compared to credentialing. You need an active PT license in the state you're practicing in, and most states now recognize telehealth cross-compliance if you see patients virtually between visits. Check your board's specific language on mobile practice — a few states have additional requirements for providers who deliver care outside a fixed facility. Colorado requires you to list your mobile practice address separately from your primary address on the license application. Mississippi doesn't have a separate category and you just operate under your standard license. Know which one you're in before you file anything.
Business formation is the boring part that eats people up because they do it wrong. You want an LLC in your home state, an EIN from the IRS, and a separate business checking account. Do not commingle funds. One client asked me why his practice was getting audited and his bookkeeper had been paying his personal car insurance from the business account for two years. That's a bad look for everyone involved. Get a bookkeeper who understands medical practice expenses within the first 90 days. The cost is roughly $150 to $300 per month and it prevents things from becoming catastrophic later. Vehicle setup runs anywhere from zero dollars if you already have a suitable van to $15,000 if you go full custom build. Here's what I actually need and what I ended up spending: a quality fold-down plinth table ($400 to $900), portable ultrasound or electrical stimulation unit ($800 to $2,400), a supply cart with therapeutic modalities ($300 to $600), a portable assessment tool kit including goniometer and dynamometer ($150 total), and climate control for equipment storage ($0 to $500 depending on van insulation). I bought a used Sprinter with the interior already paneled and spent about $3,200 on equipment. That was reasonable for starting out. The counter-intuitive thing about mobile PT is that your biggest expense isn't equipment — it's liability insurance, and most general malpractice policies don't cover mobile practice adequately. You need a policy that explicitly covers care delivered at patient residences and non-traditional settings. A standard professional liability policy from a carrier like HPSO or DocStyle will run you between $2,500 and $5,000 annually depending on your coverage limits. I almost got burned on this. My initial policy had a vague "healthcare delivery" clause and when I asked about mobile practice coverage, the agent said it was included. It wasn't. There was a separate rider. I switched carriers and the new one was clearer about what was and wasn't covered. Read the exclusions section before you sign anything. That's where the gaps live.
Documentation and EHR selection is another place people waste money. Don't buy the biggest platform. You need something that handles mobile-specific workflows: GPS visit tracking, encounter notes that work on a tablet with spotty cellular service, and automated insurance claim submission. TherapyNotes and SimplePractice both work fine for solo mobile practices. I used NetHealth for about a year and then switched because their mobile app crashed during house calls in basements with no signal. Now I use a simpler platform that prioritizes offline mode. The one I'm on now costs about $89 per month and handles 95 percent of what I need. The other 5 percent I do on paper and upload later. Here's the specific edge case that nearly killed my practice in year two: a patient's insurance denied a claim because the modifier I used on the claim form was wrong for mobile delivery in their particular plan. I had been using the same modifier for everyone and it worked fine with three different payers. Then my fourth payer came back with a denial citing incorrect place of service coding. The correct modifier for mobile PT at a patient's residence varies by payer. United Healthcare wants one thing, Medicare wants another, and a regional PPO in my area wanted a completely different code. I lost about $4,200 in denied claims over six weeks before I figured it out. Now I maintain a payer-specific modifier matrix in a spreadsheet and check it before every claim. It takes me about 20 minutes per payer panel update and has eliminated denials of this type entirely. Pricing structure determines whether you can sustain this. If you're going cash-only, charge $120 to $180 per 60-minute session depending on your market. Insurance-based reimbursement runs significantly lower — Medicare pays roughly $85 to $110 per visit depending on the CPT codes used and your local fee schedule. Self-pay patients are where the margin actually exists. I found that offering a package of eight sessions at a slight discount ($850 for eight sessions instead of $1,280 at full price) kept patients committed and improved my cash flow predictability. Most mobile PT providers who fail do it because they chase insurance volume instead of building a self-pay base. The administrative burden of insurance billing on top of traveling to each patient's home is exhausting and the reimbursement rarely justifies the time spent.

Marketing for a mobile PT business is different from marketing a brick-and-mortar clinic. You're not competing on foot traffic. You're competing on convenience and trust. The channels that actually work: direct referrals from home health agencies, partnerships with discharge planners at hospitals, and word-of-mouth from existing patients. I stopped running Google Ads after month four. They brought in leads but the conversion rate was terrible and the cost per acquisition was around $200. Instead I spent time building relationships with three home health agencies in my area and one occupational medicine clinic. Those three referral sources now generate about 70 percent of my new patients. It took me eight months to get there. The work was phone calls and meeting attendance, not ads. Scheduling is the operational bottleneck nobody warns you about. If you're doing four to six visits per day with travel time between them, you're looking at a 10 to 12 hour driving day. I learned this the hard way when I booked eight visits in one day across a 40-mile radius. I spent three hours driving and had 45 minutes left for actual patient contact time. That's not sustainable. Now I cap myself at five visits per day and zone my schedule geographically. Monday through Wednesday I work the northern part of my service area, Thursday and Friday the southern part. This cuts my daily drive time from about three hours to roughly 90 minutes and leaves me with energy to actually do good work with patients instead of arriving stressed and running on fumes. Equipment maintenance is another quiet money drain. Ultrasound heads degrade. Cable connections on electrical stimulation units fail. Portable plinth tables develop wobbly hinges from constant folding and unfolding. I budget $200 to $400 per month for equipment replacement and repair. If I don't spend it, it rolls into a fund for upgrades. Some months I spend $800. Usually it's just replacing cables and small parts. Once a year I do a full inspection of everything and replace worn components before they fail during a patient session. I once showed up to a house call with a TENS unit that had a cracked lead wire. Didn't notice it during my pre-visit check. The patient's skin got a mild burn from uneven current distribution. It was minor and treated on site, but it was a reminder that mobile equipment takes more abuse than clinic equipment and you can't assume it's fine just because it worked yesterday.
The reality of mobile physical therapy is that it works well for a certain type of patient population and it doesn't work for others. Elderly patients with mobility issues, post-surgical patients who can't easily travel, athletes who want convenience — these are your core markets. Acute trauma patients, people who need intensive manual therapy requiring a full treatment table, and patients who need equipment you can't carry in a van — these are the ones you should refer out. Knowing the boundary between what you can handle and what requires a different setting saves you from bad outcomes and bad reputation. One final thing that people overlook: continuing education requirements for mobile practice. Some states require specific training in emergency procedures for providers who work outside clinical settings. You should carry a trauma kit beyond what's in your standard PT bag. I add an AED, tourniquet, and emergency oxygen to my vehicle and I maintain a separate certification in Wilderness First Response that I renew every two years. The annual cost is about $400 and the training takes about 16 hours. It's insurance against the scenario where something goes wrong far from a hospital and you're the only trained person for a mile in any direction. That's not fear-mongering. That's arithmetic.
