Why Medical Practices Run Short on Cash
A practice pays staff, rent and supplies on a fixed schedule, but much of its revenue can arrive through insurance claims that are processed, sometimes denied and resubmitted, and paid weeks after the visit. A practice that adds a provider, changes billing systems or takes on a payer with slow processing can see its receivables grow while its bank balance shrinks.
Medical clinic financing therefore splits into three needs: covering the reimbursement lag, buying equipment, and paying for space or ownership changes.
Matching Clinic Needs to Loan Structures
| Need | Structure |
|---|---|
| Payroll and rent while claims are processed | Working capital |
| Ultrasound, EKG, exam tables, lab analyzers, EHR hardware | Equipment financing |
| New suite build-out or a second clinic | Term loan |
| A physician buying into the practice | Term loan (sometimes to the individual physician) |
| Recurring gaps from uneven claim payments | Line of credit |
Equipment Loans for Doctors
Diagnostic and treatment equipment ranges from a single exam table to full imaging systems at the high end. Equipment loans and leases for doctors are secured by the equipment, and some partners finance medical equipment specifically. Technology that dates quickly, such as imaging or lab analyzers, can be leased so the practice can upgrade at the end of the term; durable furniture and exam equipment can be bought.
A Physician Practice Buy-In Loan
When a physician buys a share of an existing practice, the financing can be a term loan, sometimes made to the physician personally rather than to the practice. The partner reviews the practice's financial statements, the buy-in agreement and the physician's own finances and income from the practice. Partners treat a buy-in much like a small acquisition; the term loan page explains what that review involves.
A Reimbursement Gap, Worked Through
Illustration only: a three-provider practice adds a fourth provider. The new provider's salary and the added staff cost $28,000 a month, and claims for the new patient load begin paying about 45 days after the first visits. Six to eight weeks of added costs, roughly $42,000 to $56,000, goes out before the matching revenue arrives. Working capital sized to that ramp, not to a full year, matches the need.
The Clinic File Partners Ask For
- Bank statements and accounts-receivable aging by payer
- Practice tax returns and current financial statements
- Model-specific equipment quotes
- The lease for any build-out or new location
- Ownership structure and any buy-in or partnership agreements
