Effective billing is crucial in medical practices. The effort to rework and refile claims is expensive and time consuming, eating into practice revenue. According to MGMA, 90% of claims denials are avoidable. Good news: Two out of three denied claims can be recovered. However, the efforts to make corrections cost an average of $25 per claim. Annually, the cost to work 100 claims/month is $30,000—on top of the estimated $6.50 for each initial submission.
