La Vila and Gernika finished eleventh and twelfth in 2021-22, but Alcobendas were automatically relegated for fielding an ineligible player.
Initially, Gernika were set to be relegated, but they argued that Alcobendas' point reduction meant the Madrid side technically finished bottom, and that they were therefore denied their rightful opportunity to play off against the runner-up from the Division B playoffs, Belenos RC.
The Spanish Rugby Federation ruled that denying either team - Gernika or Belenos - a place in the top flight would be unfair.
Gernika were given a reprieve despite finishing bottom of the table last year, meaning the division grew to 13 members.
Pozuelo won 170–46 on aggregate and retained their place in the División de Honor for the 2023–24 season.
