During the first round of the playoffs, National League regulations state that the top seeded team my play any team of its choice from the bottom 4 seeds. The next seeded team may then choose their opponent from the remaining 3 of the bottom 4 seeds and so on. The same rule applies for the Semi-Finals. During the playoffs, teams alternate venues game to game, with the highest seed playing home first.

The champions of the National League B has the opportunity to play the losing team of a Play-Out tournament from the National League A to take their spot in the league. SC Langenthal took on HC Ambrì-Piotta in a 7-game series, losing 4-1 and remaining in the National League B.
