Date of Service vs. Post Date Reports

In medical billing, reports are a key part of understanding both patient care and financial activity. Two commonly confused types—Date of Service (DOS) reports and Post Date reports—serve very different purposes. DOS reports track when care was provided, while Post Date reports track when charges, payments, or adjustments were entered. Knowing the difference ensures accurate analysis, cleaner reconciliations, and better decision-making for both providers and billing staff.
