KeepMD EOB Decoder
Decodes medical bill and Explanation of Benefits codes, terms and math so you know what you actually owe.
Reads codes from an Explanation of Benefits or medical bill (ICD-10-CM, HCPCS Level II, modifiers) and checks them against current official releases. Explains insurance terms like deductible, coinsurance and allowed amount, recomputes line and claim totals from the printed amounts, and gives step-by-step guidance for disputing a bill or appealing a denial. Read-only, no sign-in required.
Try asking Muse: "Look up the codes on my Explanation of Benefits, explain what coinsurance means, and check whether the amount I owe is right."
