Why the end of the year is the perfect time

If you have an FSA, many plans reset at the end of the plan year. That makes November and December a great time to put those health dollars to work. HSA funds roll over, but there's no better time than now to take ownership of your health and head into the new year feeling your best.

How it works

  1. Book your visit online or at any Onus location.
  2. Pay with your HSA or FSA card at checkout, just like any other card.
  3. Need a receipt? Ask at checkout, or contact us, and we'll send an itemized receipt.

HSA and FSA cards can't be used for NAD+ or Niagen.

Finish the year strong

Seven Colorado locations, nurses with emergency-room experience, and a team that's been helping Colorado live better, longer since 2014. Grab your card and book your visit.
