Emergency department
99285 — Emergency department visit, high complexity
The highest-level ER visit code. Frequently upcoded — and ER bills frequently include both a facility fee and a separately billed physician fee at this level.
- Typical setting: Hospital emergency department
- National avg charge (illustrative): Facility component $1,500–$5,000+; physician $500–$1,500.
- Most-disputed reason: Level-5 ER charge for what was a level-3 visit.
What it means
What 99285 actually means
CPT 99285 is the highest of five ER visit levels and is meant for emergencies of high severity that pose an immediate, significant threat to life or function. Real 99285 examples: stroke workup, acute MI, severe trauma, status asthmaticus.
Many ER visits that look 'serious' to a patient — chest pain that turned out to be reflux, severe migraine, abdominal pain with normal imaging — are appropriately billed at 99283 or 99284, not 99285. The dollar gap between 99284 and 99285 can be $1,500+.
Common errors with this code
What goes wrong on real bills.
Most bills that look correct still contain at least one of these issues. Up to 49% of medical bills contain errors (CFPB).
- Level 5 (99285) billed for a visit that diagnostically resolved as a lower-acuity issue.
- Both a facility level-5 charge and a physician level-5 charge billed as separate $4,000+ line items.
- Out-of-network ER physician balance-billing the patient (a No Surprises Act violation in most cases).
- Imaging or labs from the ER visit billed twice — once as part of the ER bundle, once as separate professional charges.

99285 FAQ
Plain-English answers.
Are ER bills protected by the No Surprises Act?
Yes — emergency care is a primary protection. If the ER or its physicians are out of network, you generally cannot be balance-billed beyond your in-network cost share. If a balance bill arrived, that's a federal complaint route.
What if the ER bill is just too high to pay?
Three things in order: (1) request the itemized bill, (2) check the hospital's charity care / 501(r) financial assistance policy — most nonprofit hospitals must offer it, (3) dispute upcoding before paying. Our Resolution Pack handles all three.
