IDG Composition Requirements

Required members and meeting rules for the interdisciplinary group

Quick answer

Federal rules specifying the minimum disciplines that must participate in the interdisciplinary group — at minimum an RN, physician, social worker, and pastoral or counseling services — and the meeting frequency required under 42 CFR 418.56.

What it is

The interdisciplinary group (IDG) is the team a Medicare hospice must designate to meet the physical, medical, psychosocial, emotional, and spiritual needs of patients and families. Under 42 CFR 418.56, the group must include a defined set of professional disciplines and be responsible for the patient's plan of care [1].

How it works

The IDG must include, but is not limited to, individuals qualified and competent in the following roles: a doctor of medicine or osteopathy; a registered nurse; a social worker, marriage and family therapist (MFT), or mental health counselor (MHC); and a pastoral or other counselor (42 CFR 418.56(a)(1), https://www.ecfr.gov/current/title-42/chapter-IV/subchapter-C/section-418.56). The addition of MFTs and MHCs as recognized disciplines took effect January 1, 2024 under the CY 2024 Home Health PPS final rule (CMS-1780-F)[2], which also added their qualifications to the hospice personnel standards. The hospice must designate a registered nurse who is a member of the IDG to provide coordination of care and to ensure continuous assessment of each patient's and family's needs. The group as a whole establishes, reviews, and revises the plan of care and supervises the care and services provided, with more than one IDG permitted for larger organizations as long as one designated group maintains overall responsibility for each patient.

Why it matters

IDG composition is a condition of participation, and a missing required discipline is exactly the kind of finding that can escalate to a condition-level deficiency during survey rather than a simple standard-level citation. The 2024 expansion to include MFTs and MHCs is an opportunity, not just a rule change: it widens the labor pool that can be credentialed to satisfy the counseling role amid persistent social-work and chaplaincy shortages. The higher-frequency risk, though, is participation and documentation — surveyors look for evidence that each required discipline actually contributes to care planning at the required cadence, not merely that the roles exist on an org chart. Gaps in the designated coordinating RN role ripple into assessment timelines and plan-of-care compliance.

Key takeaways

  • The IDG must include a physician, an RN, a social worker/MFT/MHC, and a pastoral or other counselor (42 CFR 418.56(a)(1), https://www.ecfr.gov/current/title-42/chapter-IV/subchapter-B/part-418/subpart-C/section-418.56).
  • MFTs and MHCs became recognized disciplines effective January 1, 2024 (CMS-1780-F)[2].
  • A designated RN member must coordinate care and continuously assess patient and family needs.
  • The IDG, as a group, is responsible for establishing and revising each patient's plan of care.
