Every growing practice eventually hits the same wall: the front desk person who used to “handle billing on the side” can no longer keep up, claims are getting submitted late, denials are piling up unread, and nobody has a clear answer for how much money is sitting in accounts receivable. If that sounds familiar, it’s a sign you’ve outgrown informal billing and need an actual team structure. The good news is that building a billing function from scratch doesn’t require hiring ten people on day one — it requires understanding which roles cover which parts of the revenue cycle, and sequencing your hires so nothing critical falls through the cracks.
Think in Terms of the Revenue Cycle, Not Job Titles
Before deciding who to hire, it helps to map the actual work that has to happen, start to finish: verifying insurance before the visit, capturing charges accurately, coding the encounter, submitting clean claims, following up on unpaid or denied claims, posting payments, and collecting patient balances. In a small practice, one or two people may wear several of these hats. In a larger practice, each becomes a distinct role. The mistake many practice owners make is hiring generic “billers” without being clear on which of these functions that person is actually responsible for — which leads to gaps where everyone assumes someone else is handling denials or patient collections.
The Core Roles You Actually Need
1. Front-Desk / Registration Staff (Insurance Verification)
This is the foundation, and it’s often underestimated. Insurance eligibility and benefits verification done incorrectly at check-in is one of the largest sources of downstream denials. This role doesn’t need to be a dedicated “biller,” but they need training on what to check (active coverage, correct plan, referral or authorization requirements) and clear escalation paths when something looks off.
2. Medical Coder
Someone needs to translate the clinical documentation into accurate CPT and ICD-10 codes. In smaller practices, especially primary care, this is sometimes done by the provider themselves or a biller with coding training. In specialties with complex coding (surgery, cardiology, oncology), a certified coder is worth the investment early, because coding errors are expensive both in denied claims and in compliance risk.
3. Claims/Billing Specialist
This person prepares and submits claims, checks for clean-claim errors before submission (mismatched patient data, missing modifiers, invalid codes), and manages the clearinghouse relationship. This is usually the first dedicated billing hire a practice makes.
4. Accounts Receivable (A/R) and Denials Follow-Up
This is the role most practices skip too long, and it’s the one that costs them the most money quietly. Someone has to actively work the aging report, follow up on unpaid claims past a set number of days, and appeal denials rather than writing them off. Without a dedicated person (or dedicated time) for this, denied and unpaid claims simply age past the point where they’re worth pursuing.
5. Payment Posting
Someone needs to accurately post insurance payments (from ERAs/EOBs) and patient payments, and reconcile them against expected reimbursement. This role catches underpayments — insurance paying less than the contracted rate — which is otherwise invisible.
6. Patient Billing / Collections
A person (or clear process) dedicated to communicating with patients about balances, setting up payment plans, and handling billing questions or disputes. This role has an outsized effect on patient satisfaction — nobody remembers a smooth claim, but everyone remembers a confusing or aggressive bill.
7. Billing Manager / Revenue Cycle Lead
Once you have three or more people in billing-related roles, someone needs to own the metrics: days in A/R, denial rate, clean claim rate, and net collection rate. This person also manages payer relationships and keeps the team’s processes updated as payer rules change.
A Practical Sequencing Approach
Practices rarely build this all at once, and shouldn’t try to. A reasonable order for most growing practices is: get registration/eligibility verification solid first, add a dedicated claims/billing specialist as volume grows, then add dedicated A/R follow-up as soon as you notice claims aging without action (this is usually the single highest-return hire, because it directly recovers money already earned), and only bring on a billing manager once you have enough staff and complexity to need someone coordinating the whole cycle rather than doing hands-on work themselves.
A Note From Practice Experience
One pattern that comes up repeatedly with practice managers who’ve built teams from the ground up: the temptation is always to hire more front-end billing staff (people submitting claims) before hiring anyone to work denials and aging A/R, because submitting claims feels like “doing the work” while chasing old claims feels like cleanup. In practice, the aging report is usually where the real money is hiding. A practice that adds one experienced A/R specialist often recovers more revenue than one that adds two more claim-submission staff, simply because nobody was going back for the money already left on the table.
Skills to Prioritize When Hiring
- Familiarity with your specific specialty’s coding nuances, not just general billing experience.
- Comfort reading and interpreting EOBs/ERAs and denial codes — this is a teachable skill, but ask about it in interviews.
- Experience with your practice management or EHR system, or at least a similar one, to shorten ramp-up time.
- For patient-facing collections roles, communication skills matter as much as billing knowledge.
Takeaway
Don’t build a billing team around generic “biller” job titles — build it around the specific revenue cycle functions your practice needs covered: verification, coding, claims submission, denial follow-up, payment posting, and patient collections. Start with whichever function is currently causing the most leakage (often denial follow-up), and add roles in the order your claim volume and complexity actually demand them.
