What to say on the phone

"I'd like the self-pay price for CPT 66821, in writing, and whether it covers facility, physician and anesthesia."

About laser treatment after cataract surgery (yag)

After cataract surgery, the membrane that holds the new lens can cloud over months or years later. CPT 66821 is the fix: a YAG laser opens a small hole in that membrane in a few minutes, in an office or outpatient setting, with no incision and no sedation. Vision usually clears within a day.

What the price covers

The hospital's price is the facility fee for the laser suite and staff. The ophthalmologist bills separately. There is no anesthesia provider; numbing drops are included.

Why prices vary

For a five-minute laser treatment, hospital facility fees vary widely. Many ophthalmologists perform it in their own office, where the total is often far below the hospital's facility fee. If a hospital's price looks high, it is worth asking the surgeon whether the office is an option.

Questions to ask

  • What is the self-pay price for 66821, facility and physician together?
  • Can this be done in the surgeon's office instead of the hospital?
  • Is a follow-up visit included?
