Write notes that support the right code
A code is only as good as the note behind it. If you're documenting periodontal procedures, start with our periodontal charting documentation guide. For general visit notes, see how to write a dental SOAP note. For how documentation gaps translate into denied claims, read how poor documentation leads to insurance claim denials.
