Supplementary Service 131M serves residential estates and schools around Bukit Purmei and Lower Delta Road with connections to Jalan Bukit Merah and Bukit Merah Town Centre. It duplicates its parent Service 131 along its entire route, and enhances connectivity for Bukit Purmei residents.

Introduced as a replacement for Feeder Service 275, this route duplicates the withdrawn Service 275 entirely. Ever since Service 131 was amended to ply Bukit Purmei Avenue in both directions in 2005, both Service 131 and 275 have been duplicating each other, and as such, Service 275 was made to operate at low frequencies (until its BSEP fleet addition in 2013). To better utilize resources, Service 275 was withdrawn entirely, and Service 131M introduced to take its place, operating only during the peak hours where additional resources are better utilized.

As a variant of Service 131, this service is wheelchair-accessible as of introduction.
