Summer

I wasn't charged at time of service (I was in too much pain to question it) and later was billed a $40 copay instead of $25, which is the rate for urgent care with my insurance.

The doctor I saw said it would take two weeks for me to have a CT scan (which is what I needed to find out what was wrong) and that I should see my GP if I wanted it faster. Thus, the visit was entirely pointless.

I spent months speaking with their billing department, trying to get this resolved (including a phone call with my insurance where they told me Sterling billed incorrectly), but they refused to change the bill. As I continued to try to get this figured out, they threatened to send me to collections over $15 (I paid them the $25 previously). (Edit, a week later: They actually did send me to collections, despite me immediately paying by phone when I received their threat. Wow, the pettiness gets even better.)

Classy, Sterling. Classy.

Edit after response from Sterling: I went to Sterling in January and was charged a $25 copay. This was asked of me upfront. In May, I was not charged upfront, clearly due to company greed of changing everyone at their urgent care to specialists. If that's how they want to do business, then so be it. But I'll go anywhere else but Sterling for urgent care in the future.
