Importing Medical Coding Systems

Several systems for medical and procedural coding can be imported into Open Dental and then attached to patient information.Coding systems allow a consistent way to organize, index, store, and retrieve clinical data between providers and care sites. EHR must be turned on in Show Features to access this areas.

EHR: Some data must be associated with a specific code to be recognized in EHR Measure Reports, or to show in clinical documents. We recommend importing all code systems. At a minimum, import RxNorms, SNOMED CT Codes, and LOINC Codes, since these code systems are used often in EHR data. CPT Codes are not required for EHR and must be purchased separately.
