CPT code 90882 is a code that’s used to bill for certain services you might provide as a mental health practitioner. The purpose of code 90882 is officially defined as billing for “environmental intervention services for medical management purposes on a psychiatric patient's behalf with agencies, employers, or institutions.”

In simpler terms, you might use this code when you collaborate with external agencies, employers, or other healthcare professionals to assess for and recommend changes to your psychiatric patient’s environment. These changes are designed to improve the patient’s well-being and treatment outcomes. The code allows you to address environmental factors that may impact a patient's mental health treatment and recovery.

This specialized psychiatric service code is less commonly used than others, and falls under the "Other Psychiatric Services or Procedures" category. 


Understanding Environmental Intervention Services

CPT 90882 encompasses a broad range of “environmental intervention services,” where healthcare providers work with third parties to create therapeutic changes in a patient's surroundings. These changes focus on making relevant changes to their surroundings to promote better health outcomes.

But what exact services does this code cover?

Key Components of CPT 90882 Services

Examples of the “environmental intervention services” that may be billed under CPT 90882 include:

  • Coordination with employers regarding workplace accommodations

  • Collaboration with housing agencies for therapeutic living arrangements

  • Working with educational institutions for academic support

  • Consulting with family members or caregivers about home environment modifications

  • Coordinating with other healthcare providers for comprehensive care planning

  • Addressing physical environmental barriers to treatment compliance

To illustrate, suppose you have a client who lives with depression and is also unhoused. Their housing status contributes to their depression symptoms. If you coordinate with community organizations to change their housing status (in order to improve depression symptoms), this could be billed with 90882.

When to Use CPT Code 90882

Healthcare providers should consider using CPT 90882 when:

  • A patient's environment significantly impacts their psychiatric condition

  • Coordination with external parties is necessary for treatment success

  • Environmental modifications are required for medication management

  • Workplace or housing situations affect the patient's mental health

  • Multiple agencies need coordination for comprehensive patient care

However, keep in mind that it’s not always appropriate to use 90882 when coordinating with other people or organizations about your client’s care. Team conferences, for the purposes of care management, are billed under another set of codes.

  • When working with an interdisciplinary treatment team (minimum of 3 qualified healthcare professionals from different specialties) with your patient present, use 90366

  • When working with an interdisciplinary treatment team with your patient not present, use 99368
