Yes, the accent still moves forward one position in the gerundive and past conjugations of auxiliary verbs such as the causative and the past.
I will give an example as follows.
書く{HL} ; 書かれる{LHHL} ; 書かせる{LHHL} ; 書かせられる{LHHHHL}
書かない{LHLL} ; 書かれない{LHHLL} ; 書かせない{LHHLL} ; 書かせられない{LHHHHLL}
書いて{HLL} ; 書かれて{LHLL} ; 書かせて{LHLL} ; 書かせられて{LHHHLL}
書いた{HLL} ; 書かれた{LHLL} ; 書かせた{LHLL} ; 書かせられた{LHHHLL}
書{か}く has the accent fall originally, so if ''-られる'' or ''-させる'' is put on the verb, the accent fall still exists.
While, ''腫{は}れる'', which is given as example in the question, doesn't have accent fall. Even if ''られる'', ''させる'', or ''させられる'' is put on a verb without any accent fall such as ''腫れる'', accent fall still does not exist.
腫れる{LHH} ; 腫れさせる{LHHHH} ; 腫れさせられる {LHHHHHH}
腫れない{LHHH} ; 腫れさせない{LHHHHH} ; 腫れさせられない{LHHHHHHH}
腫れて{LHH} ; 腫れさせて{LHHHH} ; 腫れさせられて{LHHHHHH}
腫れた{LHH} ; 腫れさせた{LHHHH} ; 腫れさせられた{LHHHHHH}
You can consider verbs with ''られる'' and ''させる'' as just verbs Group2 such as ''[食]{た}べる'', ''[開]{あ}ける'' in behavior of accent rule.
That is,
When the verb has the accent fall, [...(ら)れる]{LHHHHHHL}, [...(ら)れない]{LHHHHHHLL}, [...(ら)れた]{LHHHHHLL}, [...(ら)れて]{LHHHHHLL}
It's the same pattern as 食べる{LHL} , 食べない{LHLL}, 食べた{HLL}, 食べて{HLL}
or
When the verb doesn't have accent fall, [...(ら)れる]{LHHHHHHH}, [...(ら)れない]{LHHHHHHHH}, [...(ら)れた]{LHHHHHHH}, [...(ら)れて]{LHHHHHHH}
It's the same pattern as 開ける{LHH} , 開けない{LHHH}, 開けた{LHH}, 開けて{LHH}
(added)
Group2 means verbs whose verb basees end with vowel, such as 食{た}べる, 寝{ね}る, 着{き}る , 恥{は}じる.
While, these words as follows are categorized in another group, that is called Group1 in Japanese education.
しゃべる, 練{ね}る, 切{き}る, 走{はし}る, 書{か}く, 待{ま}つ, 飛{と}ぶ...etc.
する and 来{く}る are called Group3, each of which has irregular pattern of the inflection.
