The Anfield clash with the Hammers is the final home game before the 24th anniversary of the tragedy, which will be the first since the Hillsborough Independent Review published its findings.
In September the panel concluded that no Liverpool fans were responsible in any way for the disaster, and a lack of police control was the main cause.
The annual memorial service will be held on Monday, April 15 at Anfield at 2.45pm.
Margaret Aspinall, chair of the Hillsborough Family Support Group, told the club website: "Every day we remember those who lost their lives. During the service we will light a candle for each and every life that was extinguished prematurely and the eternal flame of the Hillsborough memorial will continue to light our way through the darkest days.
"For many, April 15 may be a working day and there will be those who are unable to attend. We invite you to join us in thought and spirit and keep us in your prayers at this difficult time."
