We’re seeing a growing number of practices run into this issue as they expand services and staffing models:

Q: I have Licensed Social Workers (LSWs) in my practice who see commercial clients under my supervision, and I bill for their services under my license with several commercial payers.

My practice—and I personally—are enrolled with Traditional Medicare.

Can my LSWs see Medicare clients, with supervision, and have those services billed under my Medicare enrollment?

A: No—and this is a critical distinction between Medicare and many commercial insurance plans.

Under Traditional Medicare, “incident to” billing is not permitted for services performed by Clinical Social Workers (LISWs) or other behavioral health clinicians such as:

  • LPCCs
  • LIMFTs
  • LICDCs

This means:

👉 You cannot bill Medicare for services performed by supervised clinicians under your license

👉 Even if you are properly enrolled

👉 And even if you are providing clinical supervision

What Medicare does allow “Incident to” billing under Medicare is limited to specific provider types, including:

  • Physicians (MD/DO)
  • Nurse Practitioners (NPs)
  • Physician Assistants (PAs)
  • Clinical Psychologists (CPs)
  • Clinical Nurse Specialists (CNSs)

Behavioral health mid-level licensure types are not included in this provision.

Why this matters

If your practice applies commercial “incident to” logic to Medicare:

  • Claims will be denied
  • Services may be non-billable
  • And in some cases, this can create compliance risk if billed incorrectly

Bottom line:

Medicare requires the rendering provider to be independently eligible and enrolled—supervision alone is not enough.

Important note on commercial payers

Many commercial insurance plans have created their own rules around supervision and “incident to” billing.

  • Some follow Medicare guidelines
  • Others allow more flexibility

Do not assume consistency across payers. Each contract should be reviewed individually.

At G&M Consulting, we help behavioral health organizations align their staffing models with payer rules—so growth doesn’t come at the expense of compliance or revenue.

If you’re expanding your clinical team or unsure how your services should be billed across payers, we’re happy to help.
