The X-ray is appropriate, but the price is well above benchmark. Medicare pricing was not supplied by the rules engine, so dollar figures are estimates.

I am a self-pay patient. After reviewing the itemized bill, I believe several charges are incorrectly coded or should not be billed separately.\n\nDisputed lines:\n\n1. CPT 99285 (ED visit level 5), charged $3,250. This visit was for a twisted ankle and lasted about 40 minutes, with one X-ray, no fracture, an elastic bandage, and ibuprofen. A level 5 code requires high-complexity medical decision making under the AMA E/M guidelines, which I do not believe the visit supports. I request that it be reviewed and re-coded to the level supported by the documentation, which appears to be 99282 or 99283. I request an adjusted amount of $300.\n\n2. CPT 73610 (ankle X-ray, 3 views), charged $640. I do not dispute that the study was performed, but the charge is far above the Medicare rate and typical cash prices. I request an adjusted amount of $130.\n\n3. HCPCS A4570 (splint / elastic bandage), charged $185. This code is not valid for Medicare, and a routine elastic bandage is a packaged supply included in the ED visit charge. I request an adjustment to $0.\n\n4. CPT 99070 (supplies and materials), charged $95. This is a non-specific code that is bundled into the visit and appears to duplicate line 3. I request an adjustment to $0.\n\nI request that you send a fully itemized bill with CPT/HCPCS codes, revenue codes, and units, and a copy of the medical record for this visit, including the ED provider note and triage record, so that the level of service can be verified. Please also send your financial assistance policy and application, and your self-pay or cash price information for these services.\n\nPlease place this account on hold and do not refer it to collections or report it to credit bureaus while this dispute is under review. If, after review, you believe the charges are correct, please provide a written explanation of the coding for each line.\n\nThank you for your prompt attention.\n\nSincerely,\n[PATIENT NAME]"},"next_steps":["Send the dispute letter by certified mail or through the billing portal and keep a copy and proof of delivery.","Request the itemized bill with codes and the full ED medical record, including the provider note and triage documentation, and compare them to the 99285 level.","Ask whether the facility is a nonprofit hospital and request its financial assistance policy, applying if you may qualify.","Look up the hospital's published cash prices under the price transparency rule and compare them to the amounts billed.","Ask whether a separate professional (physician and radiologist) bill is coming, and check it for the same coding issues.","Ask for a written hold on collections, and consider negotiating a prompt-pay self-pay discount if the facility will not re-code.","Going forward, request a Good Faith Estimate before any scheduled care as an uninsured patient.
