Joint Academy is a digital musculoskeletal care company operating in the US, UK and Sweden. We did $40M in revenue last year and are profitable. In the US we run two things: an AI Care Platform that lets physical therapy clinics deliver and bill Remote Therapeutic Monitoring (RTM) to their own patients, and a virtual physical therapy service contracted directly with health plans.

Both are growing fast, and billing is becoming a service we offer, not just a back-office function.

We're looking for a hands-on biller who knows physical therapy billing inside out and wants to build and own a billing service for a company that's scaling across the US. Your first job is billing on behalf of our clients: PT clinics using our platform for RTM. Your second is billing for our own contracts with insurance companies as we add health plans.

You're not buried in the back office. You'll sit in on client meetings, be the person our clinic partners call with billing questions, and help us turn "we bill for you" into a real, paid offering.

• Bill RTM on behalf of our PT clinic clients: prepare, submit, track and reconcile claims (CPT 98975, 98977, 98980, 98981), review documentation against payer rules, and catch errors before they become denials
• Join client onboarding and check-in calls as our billing liaison, alongside our Customer Success lead
• Submit, track and reconcile claims for Joint Academy's own virtual PT services with commercial health plans
• Work denials, appeals, ERAs/EOBs and payment posting; keep AR clean and aging low
• Help with payer enrollment and credentialing admin (NPI/PECOS, CAQH, commercial payer setup) as we add health plans
• Build simple, repeatable billing processes and tell us what we should automate

• 3+ years of physical therapy billing experience (outpatient PT, CPT 97xxx codes, modifiers, 8-minute rule, plan-of-care rules)
• Commercial payer experience and comfort with clearinghouses, ERAs and payer portals
• Experience working denials and appeals end to end
• Comfort talking to clinic owners and office managers; you explain billing clearly and calmly
• Self-directed; you'll be our only biller, so you need to run the function, not wait for instructions

• RTM or RPM billing experience (98975–98981, 99453–99458)
• Credentialing/payer enrollment experience across multiple states
• Experience at a billing company or managing billing for several clinics at once
• Familiarity with telehealth billing rules and place-of-service codes

• $30–40/hour, 1099 or W-2, your choice
• Fully remote, flexible schedule, ~10 hrs/week to start with a clear path to more hours as our clinic and health plan business grows
• A chance to build a billing service from the ground up, with your work directly visible to clients and leadership
• Direct exposure to RTM and health plan billing at national scale
