Outpatients Coding

Outpatient Coding:

Outpatient coding, it involves assigning codes to medical procedures, diagnoses, and services provided to patients who receive care on an outpatient basis. Outpatient care refers to healthcare services that do not require an overnight stay in a healthcare facility.

The most significant difference between inpatient coding and outpatient coding is the setting in which the services are provided.

We have below commonly identified POS:

11: Office visit

19: Off campus outpatient

22: On campus outpatient

The E/M section is organized into broad categories:

Office visits

  • New patient

  • Established patient.

Consultations

  • Outpatient consultation: - 99242 to 99245
