The COVID-19 pandemic deepened fault lines in American hospitals, especially those that regularly serve low income communities, which were already troubled before the deluge came. Richer hospitals made millions during the crisis, according to a new report on “Frontline” (PBS, 10 p.m., check local listings). “The Healthcare Divide” was produced in conjunction with National Public Radio.  

It comes after the latest edition of “Philly D.A.” (PBS, 9 p.m., check local listings), where the issue is the opioid crisis and how to approach it. 

Say goodbye to “Prodigal Son” (Fox, 9 p.m.), which ends tonight after two seasons.

The first season ends and a winner is named on the season one finale of “Pooch Perfect” (ABC, 8 p.m.). 

“Big Sky” (ABC, 10 p.m.) reaches its first season finale, maybe even tying up all the loose ends of the story.  It has been renewed for a second season however. 

Kevin and Madison have their respective bachelor and bachelorette parties on “This is Us” (NBC, 9 p.m.). 

“FBI” (CBS, 9 p.m.) looks into a restaurant incident that may have been racially motivated. “FBI: Most Wanted” (CBS, 10 p.m.) goes to Washington to protect a former informant.
