Healthcare payroll compliance: Overtime, shifts, and the rules that trip up practices

Your medical assistant worked 44 hours last week. You paid her at her regular rate of $22 per hour for all 44. That violates the Fair Labor Standards Act. Four hours of overtime at time-and-a-half were owed but unpaid. The penalty is not just the $44 in missed wages. It is back pay, liquidated damages of equal amount, and DOL civil money penalties up to $2,374 per willful violation under the current annual adjustment.

Healthcare payroll compliance is more complex than most industries. Medical practices operate with shift differentials, rotating schedules, mixed exempt and non-exempt staff, and on-call time. Payroll is typically the largest single component of medical practice overhead, which means errors compound quickly.

The overtime rules that catch medical practices

The FLSA requires non-exempt employees to receive overtime at 1.5 times their regular rate for all hours worked beyond 40 in a workweek. In a medical practice, four complications make this harder than it sounds.

The regular rate is not the same as the hourly rate. Shift differentials must be included. A medical assistant earning $22 per hour with a $3 evening differential for 10 hours has a regular rate of $22.75 for that week. Overtime is calculated at $22.75 x 1.5, not $22 x 1.5.

Non-discretionary bonuses must also be included. A monthly productivity bonus must be factored into the regular rate for any overtime week. Calculating overtime on base rate alone underpays the employee and violates the FLSA.

The 8/80 exception applies to hospitals and residential care facilities only. A physician-owned outpatient practice using this alternative overtime calculation creates liability with every payroll cycle it applies it.

On-call time may be compensable. A nurse required to stay on premises during on-call hours is working and must be paid. A nurse who carries a phone but can use the time freely is generally not working during on-call hours, though she must be paid for time spent responding to calls.

Exempt versus non-exempt: Where medical practices misclassify

Exempt employees are excluded from overtime if they meet both a salary threshold and a duties test. Misclassifying a non-exempt employee as exempt means they are owed back overtime for every hour over 40 they have worked.

Practice managers and office managers may qualify for the administrative exemption if they earn at least $684 per week on salary and exercise independent judgment on significant business matters. An office manager who primarily performs clerical tasks may not qualify, regardless of title.

Medical assistants are almost always non-exempt. The learned professional exemption requires advanced knowledge customarily acquired through prolonged specialized instruction. Medical assistants, even those with certification, do not meet this threshold. Paying a salary does not change this: if they exceed 40 hours, overtime is owed.

Nurse practitioners and physician assistants generally qualify under the learned professional exemption, but only if paid on a salary basis of at least $684 per week. An NP paid hourly is non-exempt and entitled to overtime regardless of their professional qualifications.

Shift differential and scheduling compliance

Shift differentials must be consistently applied and included in overtime calculations. If your handbook specifies a $3 evening differential, it must be paid for every qualifying hour and folded into the regular rate for overtime weeks. Inconsistent application creates both compliance exposure and employee relations problems.

Meal and rest break compliance is state-specific. Federal law does not require breaks, but many states do. California requires a 30-minute meal break after the fifth hour and a 10-minute rest break every four hours. Routinely having staff work through lunch in such states carries a penalty of one hour of pay per missed break per employee.

Multi-location and multi-state complications

State overtime rules may exceed federal requirements. California requires daily overtime after 8 hours in a day, not just 40 in a week. An employee working four 10-hour days earns 8 hours of daily overtime even though the weekly total is 40 hours. A practice applying only the federal standard in California is underpaying with every cycle. Payroll tax obligations follow the work location, so practices with employees in multiple states must confirm withholding obligations for each state where work is performed.

Five steps to lock down healthcare payroll compliance

1. Audit every position's exempt/non-exempt classification. Review each job description against the FLSA duties test. Do not rely on job titles. Document the analysis and keep it on file.

2. Verify overtime calculations include all compensation components. Shift differentials and non-discretionary bonuses must be in the regular rate. When underpayment is discovered, the guide to adjusting journal entries covers how to correct prior-period payroll errors through proper accounting entries.

3. Implement time tracking for all non-exempt employees. Every hour worked, including on-call response time, must be captured. Electronic tracking reduces the gaps that manual timesheets leave.

4. Review state-specific requirements for every state where employees work. Meal breaks, rest breaks, daily overtime, and split shift premiums vary by state. Compliance follows the employee's work location, not the practice's headquarters.

5. Document everything. Maintain classification analysis, time records, overtime calculations, and policy acknowledgments. The monthly bookkeeping checklist includes payroll documentation as part of the standard month-end close. When the DOL audits, documentation is the defense. An on-demand CFO can run quarterly classification audits before a DOL examiner does it for you.

Frequently asked questions

What is the FLSA statute of limitations for unpaid overtime claims?

Two years for unintentional violations, three years for willful violations. A DOL investigation can reach back up to three years of payroll history, with liquidated damages on top of each year of back pay. The clock runs from each pay period in which the underpayment occurred, not from when the audit opens.

Can a medical practice give compensatory time off instead of overtime pay?

No. Compensatory time in lieu of cash overtime is permitted only for state and local government employers under the FLSA. Private medical practices must pay overtime in cash. An agreement where employees voluntarily accept comp time instead of overtime wages does not constitute compliance. The liability for unpaid overtime remains regardless of what both parties agreed to.

How are locum tenens physicians treated for payroll purposes?

Locum physicians placed through a staffing agency are generally employees of the agency, which shifts most payroll and compliance obligations to the agency. A practice that hires locum physicians directly or exercises significant control over their schedule may have employer obligations of its own. The classification depends on specific engagement terms and should be reviewed before the engagement begins.

Does paying a salary make any employee exempt from overtime?

No. Salary is only one of two required conditions for exemption. The employee must also satisfy the FLSA duties test for the administrative, executive, or professional exemption. A salaried clinical coordinator or senior medical assistant who does not meet the duties test is entitled to overtime. The salary provides no overtime protection on its own.
