What is IDG? The hospice interdisciplinary group

IDG, in one sentence

The Interdisciplinary Group (IDG) is the required hospice care team that plans, reviews, and revises every patient’s care together. Under 42 CFR §418.56, the IDG must include, at minimum: a doctor of medicine or osteopathy, a registered nurse, a social worker, and a pastoral or other counselor [1].

IDG is the operating heartbeat of a hospice. Nothing about a patient’s plan of care — medication changes, level-of-care decisions, family goals, bereavement risk — is meant to sit inside a single discipline’s head. The plan lives in the IDG.

Who must be on the IDG

The four required members under CMS Conditions of Participation:

• Physician (MD or DO) — typically the hospice medical director; may be complemented by attending physicians.
• Registered nurse — usually the case-managing RN for that patient.
• Social worker — addresses psychosocial, family systems, and community-resource needs.
• Pastoral or other counselor — typically a hospice chaplain; may be a bereavement counselor for that patient’s specific plan.

Most hospices also include the hospice aide, volunteer coordinator, therapies (PT/OT/ST) where relevant, and bereavement coordinator. On complex patients, the pharmacist and dietician may attend.

How often IDG must happen

Per CoPs, the IDG must meet at least every 15 calendar days to review, update, and revise each patient’s plan of care [1]. Most hospices convene the full IDG weekly.

“Meeting” here means a real interdisciplinary conversation. Passing a form around doesn’t satisfy the CoP — a surveyor is looking for evidence of actual clinical decision-making, documented back to each patient’s plan.

What “meaningful participation” looks like

The IDG note should show that each required member contributed to the plan review. For a well-run IDG on a specific patient, expect:

• A clinical status update from the RN (symptoms, functional status, recent changes).
• A medical judgment from the physician (prognosis, medication adjustments, level-of-care recommendation).
• A psychosocial update from the SW (family dynamics, caregiver strain, community resources).
• A spiritual/existential update from the chaplain or counselor.
• Contributions from the aide when observations affect the plan (skin, appetite, family interaction).
• A revised plan of care reflecting the discussion — not just a checkbox.

Running an IDG your clinicians actually value

The single biggest predictor of retention on a hospice team is whether IDG feels like a real clinical conversation or a paperwork ritual. What consistently works:

1. Rotate the discussion order so the same patient isn’t always first (or last).
2. Time-box per patient based on acuity, not equally.
3. Follow the RN’s lead for straightforward patients; escalate to full-team discussion for complex ones.
4. Capture decisions, not narration. The IDG note should read like a plan revision, not a summary.
5. End on a wins round. Grief work is heavy; teams that acknowledge good deaths and family gratitude stay together longer.
