Cash or insurance?
At 5 of 5 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 2 it is below every plan's rate. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
What it is
This is the fourth of five emergency department visit levels, used for a problem of moderate complexity, often one that needs several tests, imaging or medicines. The level is assigned after the visit: doctors pick it by the complexity of their medical decision making, and hospitals pick the facility level by the care and resources used, so a patient cannot choose it in advance.
What the price covers
The hospital price for this code is the facility fee for the ER visit. The emergency physician bills separately, and lab tests, imaging, medicines and procedures are added on top.
