How many Hematology & Oncology private practices are in Illinois?

There are 636 physician-owned hematology & oncology private practices in Illinois, verified against the NPPES NPI Registry. All are independently operated. Hospital-employed, government, corporate, and academic positions are excluded.

How does the buy-and-bill chemotherapy model work in private oncology practices in Illinois?

In the buy-and-bill model, the oncology practice purchases chemotherapy drugs from a distributor (often through a Group Purchasing Organization for better pricing) and then bills payers for drug administration at the payer's contracted rate. Under Medicare Part B, reimbursement is typically at ASP (average sales price) + 6%. The spread between acquisition cost and reimbursement rate is the drug margin. Practices with favorable GPO contracts and a high commercial payer mix generate substantial drug margin revenue that does not exist in hospital-employed oncology.

What entity type do Hematology & Oncology private practices in Illinois use?

Most Hematology & Oncology private practices in Illinois are structured as PC, PLLC entities. The choice depends on state law, tax strategy, and liability preferences. A healthcare attorney can advise on the right structure.

What is a physician-owned Hematology & Oncology practice?

A physician-owned Hematology & Oncology practice is one where licensed physicians hold controlling ownership. This distinguishes it from hospital-employed positions, corporate medical groups, or practices backed by private equity, where non-physician entities own or control the business.

What does NPPES Verified mean?

NPPES stands for the National Plan and Provider Enumeration System, a federal database maintained by CMS. Every practice in this directory has an active NPI (National Provider Identifier) record in NPPES, which confirms it is a registered medical practice in the United States.

What does the Corporate-Acquired or MSO-Affiliated flag mean?

The Corporate-Acquired flag indicates the practice was historically physician-owned but has since been acquired by a corporate entity such as Optum or UnitedHealth Group. The MSO-Affiliated flag indicates the practice participates in a Management Services Organization, which provides administrative infrastructure while physicians retain ownership at the practice level. These flags help physicians understand the ownership structure before reaching out.
