Per Diem roles, on the other hand, typically offer daily shifts at local healthcare settings , providing direct income without long-term commitments.

Understanding the nuances of each option can help you determine which option aligns best with your professional goals and personal lifestyle.

This blog gives you complete insight into the key differences, benefits, and considerations of Locum Tenens and Per Diem work to help you make an informed decision.

Locum Tenens

Locum tenens, Latin for “placeholder,” refers to a doctor who serves as a substitute provider on a short-term basis. This arrangement helps healthcare facilities fill staffing voids with licensed physicians.

For the locum tenens doctor, life holds a series of adventures in diverse places. A doctor may spend a month in a rural health center, getting to know the patients and staff, then move on to a large urban hospital to cover a department during staff shortages.

While the constant relocation demands energy, for those doctors who want to escape permanence and crave new experiences, the transient existence of a locum tenens beats being fixed in one setting.

💡 Do you Know? The requirement of locum tenens physicians in the US is expected to increase, because AAMC predicted a shortage of 100,000 physicians by 2030.

CMS Guidelines for Locum Tenens Physicians

The CMS allows payment for services provided by locum tenens physicians, but you must follow the guidelines closely.

This passage explains the rules for locum tenens physicians, specifically within the Medicare program. It’s important because it clarifies who can be a locum tenens physician, what limitations there are on using them, and how billing is handled.

Here’s a breakdown of the key points for locum tenens:

Qualifications for Locum Tenens Doctors

• They need a valid National Provider Identifier (NPI) which is a unique identifier for healthcare providers.
• They must have a full, unrestricted medical license to practice in the state where they’ll be working.
• Interestingly, they don’t have to be enrolled in Medicare themselves and their specialty can be different from the regular physician they’re replacing.

Limitations on Using Locum Tenens

• They can’t be used to permanently expand a practice or fill gaps for more than 60 days, with an exception for military service.
• The rules outlined here specifically apply to Medicare. Other insurance providers (like Medicaid or private insurance) might have different policies regarding locum tenens. It’s important to check with them.

Billing for Locum Tenens Services

• The locum tenens physician themselves can’t directly bill Medicare for their services.
• The healthcare practice that hires them bills under the original physician’s name and billing number, but with a special code (modifier Q6) to indicate it was a locum tenens doctor providing the care.
• The practice needs to keep records of all services provided by the locum tenens physician.

Important Reminders

• Non-physician providers like nurse practitioners (NP) or physician assistants (PA) can’t be used as locum tenens under Medicare.
• The responsibility falls on the healthcare practice to make sure they follow these guidelines. There can be risks if they don’t.

Per Diem

A per diem physician is one who works on a day-to-day basis, taking shifts as needed by the healthcare facility. The term comes from Latin, meaning “per day.”

This arrangement provides flexibility for both the doctor and the facility, as the physician can choose when to work while the facility brings in extra help during busy times.

For example, Dr. Smith may work a few shifts per week at the local hospital to fill in when the regular doctors are unavailable. The per diem role allows Dr. Smith to balance his professional and personal life. He gets to help patients when it’s convenient for him, without the commitment of a full-time position. Meanwhile, the hospital benefits from having an experienced doctor to provide care when patient loads are high.

Overview of Per Diem Guidelines

Think of a per diem rate as a daily flat fee that covers a patient’s stay in a healthcare facility. This is particularly useful for settings where patient needs can vary significantly day-to-day, like skilled nursing facilities (SNFs).

CMS, the Centers for Medicare & Medicaid Services, primarily uses per diems for SNF stays under the Medicare Prospective Payment System (PPS). This system establishes a base national rate per day, adjusted for various factors to reflect the patient’s specific needs. These adjustments can include:

Resource Utilization Groups (RUGs)

Categorize patients based on their level of physical and cognitive impairment, impacting nursing staff needs.

Functional Impairment Classification (FIC)

Considers the patient’s ability with daily activities (bathing, dressing, etc.), affecting therapy needs.

Comorbidities

Presence of additional medical conditions can influence the complexity of care.

Wage index

Takes into account geographic variations in labor costs for SNF staff.

Other then SNFs

Per diems are less common for hospital stays under Medicare. Here, a system based on Diagnosis Related Groups (DRGs) is used, which considers the patient’s diagnosis and typical treatment course to determine payment.
