Fractional CFO for Healthcare Practices

Healthcare finance is unlike any other service business. Gross charges are fiction; what matters is net revenue after contractual adjustments, and that number is a function of three things the P&L does not show directly: patient volume, payer mix, and each payer's contracted rates and payment behavior. A practice that only watches volume can grow itself into lower profit.

The CFO engagement covers the layer above the books: a net-revenue forecast built payer by payer, independent oversight of the revenue cycle (AR, denials, collection rates), provider compensation modeling, capital decisions with real breakeven math, and a monthly reporting pack the physicians can govern from in one meeting. It also gives the practice a financial counterpart for banks, landlords, and buyers, conversations practice administrators are rarely staffed to carry alone.

The engagement runs on clean practice books and reconciled billing data. For how the general fractional model works, see the fractional CFO services page; for the tax and accounting side of physician practices specifically, our CPA services for physicians page covers the foundation this builds on.

The engagement usually earns its fee when several of these are true:

• The practice has 3 to 30 providers, or fewer providers across multiple locations.
• Revenue comes from a mixed payer base, and nobody currently tracks net revenue per encounter by payer.
• Provider compensation is contested, opaque, or paid on a formula nobody has re-modeled in years.
• A significant capital decision is live or recurring: imaging equipment, a surgical suite, a new location, an EHR migration.
• The billing function (in-house or RCM vendor) reports on itself with no independent review.
• The owners cannot say what a 5-point payer-mix shift would do to annual profit.

Solo and two-provider practices usually get more value from clean books and proactive tax planning first. That foundation, and when to add the CFO layer, is exactly the conversation a free initial consultation settles.

The healthcare forecast is built from the reimbursement engine up, not from last year's P&L down:

Volume, by service line. Encounters, procedures, or studies, forecast from provider schedules, historical seasonality, and referral patterns, per provider and per location.

Times payer mix. The share of that volume attached to each payer category (commercial, Medicare, Medicaid, self-pay), tracked monthly, because mix drifts continuously and every point of drift reprices the whole practice.

Times net rates, with lags. Each payer's effective collected rate per encounter, derived from actual remittance history rather than the fee schedule, with that payer's real payment lag and denial behavior built in. Commercial claims paying in 30 days and a slower payer paying in 75 produce very different Novembers from identical Octobers.

The output is a rolling 12-month net-revenue forecast and a 13-week cash view that already knows about payroll, rent, malpractice premiums, equipment debt service, and the quarterly items that ambush practices. Every assumption (volume, mix, rate, lag) is visible and testable, so when reality diverges, the model shows which assumption broke, which is the difference between a forecast and a guess.

1. AR lag and denials: the work-to-cash gap nobody owns.

Between claim submission, payer processing, denials, and rework, weeks or months separate the visit from the deposit, and every percentage point of denied or written-off claims is pure margin. When the billing function reports on itself, degradation shows up as a slowly rising days-in-AR figure nobody is accountable for. The CFO tracks net collection rate and AR aging by payer independently, reconciles billing-system totals to actual bank deposits, and puts denial trends on the monthly agenda with an owner attached.

2. Payer-mix drift: the silent repricing.

No contract was renegotiated, no fee changed, and yet margin fell, because the mix of who pays shifted a few points toward lower-paying coverage. This is the most common and least diagnosed margin problem in private practice. The fix is measurement first (net revenue per encounter by payer, monthly), then deliberate response: scheduling and capacity decisions, referral development, and payer contract renegotiation priorities based on which contracts actually matter.

3. Provider comp outrunning collections.

Comp plans keyed to production (charges or wRVUs) pay providers when the work happens; the practice gets paid when the payer pays, at the payer's rate. In a drifting mix, production-based comp can grow while the cash to fund it shrinks, and the gap lands on the owners. The CFO monitors the provider comp ratio (compensation as a share of net collections) and flags the divergence quarters before it becomes a partner dispute.

Most practice comp disputes are not really about fairness philosophy, they are about numbers nobody has actually run. The CFO's contribution is to price the alternatives against the practice's real prior-year data and show every provider what each formula would have paid them:

• Productivity models (per wRVU or per collections): strong incentives, but they import the payer mix into each provider's paycheck and can starve citizenship work like call coverage and supervision.
• Base plus incentive: predictable income with an upside kicker; the design work is in setting thresholds that are ambitious without being fictional.
• Equal share with expense allocation: simple and collegial until utilization diverges; the model shows exactly when that point arrives.

The model also handles the allocation questions that sink plans in practice: how shared overhead is split, how mid-level provider production is credited, and how new-provider ramp-ups are funded. For owner-physicians, comp design also interacts with entity structure and owner payroll decisions, which we coordinate with the tax side rather than leaving comp and tax planning to contradict each other.

The same framework prices every capital question a practice faces: the additional exam room, the second location, the surgery center share, the EHR migration. The inputs change; the discipline (all-in monthly cost, honest contribution margin at your payer mix, breakeven volume with a safety margin) does not.

• Net-revenue P&L by location and service line, against budget, with variances explained in plain English.
• Payer-mix report: volume share and net revenue per encounter by payer, trended monthly.
• Revenue cycle scorecard: net collection rate, days in AR, AR aging by payer, and denial rate, reconciled to bank deposits.
• Provider dashboard: production, collections attributed, and comp ratio per provider.
• Staffing and overhead ratios: clinical and admin payroll as a share of net revenue.
• Capital tracker: equipment debt schedule and performance of prior purchases against their original breakeven models.
• 13-week cash forecast, with days cash on hand and any week approaching the floor flagged.

Physicians are scientists; they govern well when the instrument panel is honest. The package exists so the monthly owners' meeting starts from agreed facts and spends its time on decisions.

Everything is tracked by provider and by location. Practice-wide averages let one strong service line carry a failing one invisibly, which is comfortable right up until the strong one has a bad year.

Monthly. The reporting pack is delivered and reviewed with the owners or the executive committee: revenue cycle scorecard, payer-mix trend, provider dashboard, cash. Denial and AR issues get owners and deadlines while they are one month old.

Quarterly. Payer contract review (which contracts drive profit, which renewals to fight for), provider comp true-ups against the model, capital pipeline review, and coordination with the tax team on estimated payments and any purchase timing, so tax planning runs from the same forecast as everything else.

Annually. Budget by location and service line, fee schedule and contract renegotiation strategy, comp plan refresh with the year's actual data, capital plan for the coming year, and the year-end tax handoff: closed books, fixed asset schedule, and a decision calendar the tax side already saw coming.

• Margins fell while volume grew, and nobody inside the practice can say precisely why.
• A comp dispute is brewing. Providers suspect the formula is unfair, and there is no neutral model to test the suspicion against.
• A six-figure capital decision is live: equipment, a buildout, a second location, and the only analysis so far is the vendor's brochure.
• The billing vendor's reports stopped being believed, or days in AR crossed a threshold the owners only discovered by accident.
• A transaction is on the horizon: a new partner buying in, a retiring partner cashing out, or an approach from a group or private equity buyer, and the practice needs its numbers defensible before anyone else looks at them.

For what the engagement should cost, see the fractional CFO cost guide; for the build-vs-hire question, the fractional vs full-time CFO comparison lays out the decision. Most practices under 30 providers land firmly on fractional.

• Practice management and billing data reconciled to the general ledger monthly: charges, adjustments, and payments in the PM system tied to actual deposits.
• A monthly close on a schedule, every bank, merchant, and loan account reconciled.
• Location and service line tracking in the ledger, so the P&L can answer questions at the level decisions get made.
• Payroll mapped by provider and department, because comp modeling and staffing ratios die without it.
• A maintained fixed asset schedule for equipment, tied to the debt schedule and to the tax side's depreciation records.

Where this layer is missing, we scope the cleanup first and then start the CFO cadence. A payer-mix model built on unreconciled billing data produces precise nonsense, and precise nonsense is more dangerous than no model at all.
