Common denial-code categories
Common categories include eligibility or coverage, authorization, coding or claim-data mismatch, duplicate claims, missing information, timely filing, network status. Noncovered services. Use the category as a starting point, then open the specific denial guide that matches the facts.
Denial-code action table
For each code or category, identify the plain-English meaning, common reason, facts the consumer should check, action owner. Likely path.
Inaccurate claim data usually returns to provider billing. Payer processing may need reprocessing or review a supported disputed decision may fit appeal.
Do not treat a top-code list as a diagnosis
Lists of common or top denial codes are useful only when they lead to a concrete check. Start with Medical billing denials, Denial code CO-197, Coding mismatch denial. Frequency-limit denial, then verify the payer's explanation.
Do not assume a code has one universal meaning or ask a provider to make an inaccurate change.
