A computer-implemented method for real-time coding of medical group codes such as diagnosis and procedure related groups is described. In one embodiment, one or more initial medical group codes may be assigned to a patient record based on a first set of inputs. Upon assigning the one or more initial medical group codes, a coding summary of the one or more assigned medical group codes may be displayed. While displaying the coding summary, at least one input from a subsequent set of inputs may be received and updating one or more medical group codes in the patient record.
