The former military dictator was admitted to the AFIC on January 2 when he complained of heart problems on his way to a special court set up for his high treason trial for abrogating the constitution and detaining judges in 2007.
Musharraf is facing five counts of high treason that potentially carry death penalty or life imprisonment.
Since his return to Pakistan from self-exile in March last year, Musharraf has faced prosecution in four major cases, including for his alleged involvement in the murder of former prime minister Benazir Bhutto in 2007 and the killing of Baloch nationalist leader Akbar Bugti in 2006.
Musharraf was indicted on Monday by a special court hearing the high treason case against him, becoming the first-ever military ruler to face criminal prosecution.
