Practice profitability — where the margin actually comes from.

What to track.

• Provider-level P&L — collections by provider net of variable costs and a fair allocation of overhead.
• Location margin — especially for multi-location practices.
• Service-line margin — some procedures and visit types subsidize others.
• Payer mix and contract performance — not all payers pay the same for the same work.
• Staffing ratio — FTEs per provider, per visit, per dollar of collections.
• EBITDA margin — the number that drives valuation.

Common problems.

• Overhead is allocated equally, hiding which providers actually carry their cost.
• Service-line economics aren’t known — low-margin services persist out of habit.
• Staffing is added in response to growth without checking whether collections support it.
• Margin compression is blamed on payers when the real driver is internal cost creep.

Profitability is not one number.

A practice can be profitable in aggregate while losing money on individual service lines, providers, or locations. The owner who only watches the bottom line is flying blind to the choices that matter most. Real profitability work looks at:

• Gross margin by service line — primary care, procedures, ancillaries, retail, telehealth.
• Provider productivity — revenue per provider, collections per RVU, panel size, schedule utilization.
• Location P&L — if multi-site, each location stands on its own.
• Payer profitability — some contracts cover their cost; some don’t.

The hidden costs.

The cost categories that erode practice margin without anyone noticing:

• Staffing overhead per FTE has crept up faster than reimbursement for most practices since 2020.
• Software stack sprawl — EHR, billing, scheduling, patient communication, telehealth, payroll, HR, marketing. Most practices pay for tools they don’t fully use.
• Supplies and pharmaceuticals with poor par-level discipline.
• Compliance and credentialing — necessary but often duplicated across vendors.

A short example.

A 3-location dermatology group looked profitable consolidated. Pulling location-level P&Ls, one location had been operating at a 4% loss for two years. Lease structure, staffing model, and patient mix at that site were fundamentally different. The owner had been subsidizing it without seeing it. The fix wasn’t closing the location — it was restructuring the staffing model and renegotiating the payer mix for that geography. Within 12 months, that location contributed to consolidated profit.

Questions practice owners ask.

What’s a healthy operating margin for a medical practice? Wide range. Primary care often runs 8–12%, specialty practices 15–25%, surgical groups higher. The number matters less than whether margin is stable, growing, or eroding over time.

Should we drop low-paying payers? Only with full understanding of patient volume, referral patterns, and substitution. Dropping a payer always looks better on paper than in the schedule. Model it before deciding.

How often should we look at this? Quarterly for service line and location P&Ls. Monthly for provider productivity and the top expense categories.
