The 84-times capped Wales skipper suffered a knee injury in September and was out until February, making two substitute appearances for Cardiff before picking up a calf complaint.
But Rob Page (49) has named the midfielder in a 28-man squad as Wales seek to qualify for a third successive European Championship and fourth major tournament in five.
Wales host Finland in a Euro 2024 play-off semi-final in Cardiff on March 21st, with the winners at home against Estonia or Poland five days later to determine a place in Germany.
Ramsey, speaking to Sky Sports on Saturday about his playing return, said: "I'm optimistic and hopefully I'll get back on that pitch as soon as possible.
"These play-off games at home are vital. We've had so much success of late over the last four tournaments.
"The expectation is on us now to keep qualifying for these tournaments."
There are also recalls for Adam Davies, Charlie Savage, Dylan Levitt, Josh Low, Rabbi Matondo, Rubin Colwill and Wes Burns.
Low replaces Tom Lockyer, who played in Wales' last Euro 2024 qualifier against Turkey in November.
Luton defender Lockyer suffered a cardiac arrest in a Premier League game at Bournemouth in December.
