What are Hospice ICD-10-CM Codes?
Hospice care is a form of palliative care that enhances the quality of life for individuals facing a terminal illness. It prioritizes comfort care, symptom relief, and emotional support for hospice patients rather than curative treatment. Accurate use of ICD-10-CM codes is essential for proper documentation, billing, and Medicare or Medicaid reimbursement in a hospice setting.
This comprehensive guide outlines the most current hospice ICD-10 codes used in medical care as of 2025, based on guidance from CMS, the American Hospital Association, and current coding standards.
- Z51.5 – Encounter for palliative care: This is the primary ICD-10-CM code used to report palliative service encounters in hospice or home health programs. It applies when treatment focuses on relieving suffering, improving quality of life, and addressing emotional and spiritual needs in the final stages of life. This code should be used only when palliative care begins during the encounter and is exempt from Present on Admission (POA) reporting.
In addition to Z51.5, several other ICD-10-CM codes may be assigned when addressing comorbidities, status changes, or complications relevant to hospice patients:
- Z85.23 – Personal history of malignant neoplasm of digestive organs: Used to document prior cancer diagnoses in the digestive tract (e.g., liver, pancreas, colon). This diagnosis code is relevant if the patient’s terminal condition stems from or is influenced by this history.
- R55—Syncope and collapse: This condition indicates a temporary loss of consciousness, often related to disease progression, circulatory decline, or medication effects. It may impact treatment decisions and DNR status (Do Not Resuscitate).
- R57.0 – Cardiogenic shock: Describes a life-threatening condition often seen in hospice patients with heart failure, where the heart cannot pump enough blood. It may trigger urgent care protocols in the hospice plan.
