Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with advanced, life-limiting illness (for example, metastatic lung cancer, end-stage heart failure, or advanced neurodegenerative disease) who receives a documented palliative care consultation or ongoing palliative care service at any point during the measurement period. The clinical workflow begins when the primary treating team or outpatient clinician refers the patient to the palliative care team for symptom management, goals-of-care discussion, advance care planning, or coordination of complex care needs. A palliative care clinician (physician, nurse practitioner, or physician assistant) performs an initial assessment that includes symptom review (pain, dyspnea, nausea, anxiety), psychosocial and spiritual screening, medication reconciliation, and identification of goals and preferences. The team documents a plan that may include medication adjustments, referrals to hospice or subspecialty services, advance directive completion, family meetings, and follow-up visits. Services may occur in inpatient hospital settings, outpatient clinics, home visits, long-term care facilities, or via telehealth. The encounter is documented in the medical record with clear start and stop times, clinician identity and credentials, clinical findings, interventions, and goals-of-care discussions to support billing for palliative care services reported with G9988 during the measurement period.
