Amy MacMahon on Tuesday said her recovery was far from over despite medical leave stint since the two-car collision at a busy Brisbane intersection on February 12.

But she was grateful to be back at work after suffering head and suspected spinal injuries in the Kangaroo Point crash.

Dr MacMahon was taken to hospital in a serious but stable condition after her Toyota Prius and a Hyundai i30 collided.

"I returned to parliament today after two months of medical leave following a car crash and I have some recovery ahead of me but I'm feeling immensely grateful to be back at work," she told parliament on Tuesday.

The MP had left a function and was on her way to another community event when the collision occurred.

Dr MacMahon said Greens Brisbane city councillor Trina Massey had called an ambulance and stayed with her until help arrived.

She thanked Ms Massey and members of parliament who reached out during her recovery along with the community, parliamentary and Greens staff as well as emergency services.

"Most importantly thank you to the doctors, nurses, paramedics and allied health workers at the Princess Alexandra Hospital for their ongoing care," she said.

"I am a product of the public health system and I stand here today thanks to them."

Rani Paige Lowry was charged over the crash and appeared in Brisbane Magistrates Court on March 14.

Police allege Lowry was driving the Hyundai i30 at more than 80km/h in a 60km zone and a passenger asked her to slow down before the incident.

Lowry is on bail, with her matter adjourned until April 22.
