For employers with self-funded health plans and the third-party administrators (TPAs) supporting them, a specialist referral can influence spending well beyond the initial visit. Referrals help determine where an employee receives care, which treatments they receive, and how their care is managed.

 

The financial stakes are high. An analysis by McKinsey found that spending in six major specialty areas grew 35% faster than all other medical spending between 2020 and 2023. Patients receiving care in those specialties accounted for 68% of combined commercial and Medicare medical spending in 2023. Though these figures capture overall spend for patients receiving specialty care, rather than costs directly attributable to a referral, they underscore the importance of specialist selection. (McKinsey, 2025)

 

Employer-specific research reinforces the conclusions from the McKinsey analysis. A previous study in Health Affairs found that an employer direct-payment program combining selected providers with bundled payments was associated with a 10.7% reduction in episode prices across three surgical procedures. Employer payments fell by an average of $3,582 per episode. The findings reflect the results of the full program, rather than provider selection alone. (Whaley et al., 2021)

 

Network access is only part of the picture

 

Employers and TPAs invest in network coverage and negotiated rates. Those measures help establish access and price, but they do not reveal how well a specialist treats a particular condition or manages the full cost of care. An ‘in-network’ referral can still lead to care that varies considerably in quality, treatment approach, and downstream expense.

 

Yet referral decisions are not always based on reliable performance data. A 2023 qualitative study of 21 primary care physicians found that surgical referral decisions relied on professional experience, subjective assessments of quality, and perceived convenience. Physicians described available quality data as difficult to access, insufficiently specific, or difficult to trust. (Naik et al., 2023)

 

Relationships and local knowledge are valuable when making referrals. Without objective performance data, however, it is difficult to assess whether a familiar specialist consistently delivers appropriate care, achieves strong outcomes, and manages total cost of care effectively.

 

The downstream knock-on impacts

 

Specialty referrals are a familiar constant in any primary care office. Consider a patient referred for persistent knee pain. The specialist’s approach can influence whether treatment begins with conservative care, when surgery is recommended, where it takes place, and how rehabilitation is coordinated. Each decision can affect recovery and total spending.

 

When tests are duplicated, treatment is unnecessary, poorly coordinated, or complicated by preventable problems, the consequences can include additional procedures, hospital visits, and prolonged recovery. Employees may face more out-of-pocket expenses and time away from work, while employers absorb higher claims costs. A negotiated rate for the initial visit tells employers little about the costs that may follow based on the specialist’s treatment decisions. (McKinsey, 2025)

 

A stronger referral process pairs clinical judgment with condition-specific evidence on outcomes, complications, utilization, and costs across the episode of care. Comparisons should account for patient complexity and focus on care that the specialist realistically influences. (Broulette et al., Milliman MedInsight, 2025)

 

Your referral strategy

 

For employers and TPAs, referral strategy is an important component of broader network design and contracting. Evaluating specialists beyond their network status and office visit fees can help protect employee health and manage total cost of care.
