Course curriculum overview

Understanding facility coding is vital when working in the hospital and ambulatory surgery center (ASC) settings, where reimbursement is based not on professional services provided, but on the resources used during the patient encounter.

The COC training will cover coding fundamentals including CPT®, ICD-10-CM, and HCPCS Level II coding, along with the Outpatient Prospective Payment System (OPPS) and an introduction to ICD-10-PCS.

Outpatient coding training objectives

  • Understand outpatient facilities and their departments including outpatient services at hospitals, teaching hospitals, critical access hospitals, ambulatory surgery centers (ASCs), and comprehensive outpatient rehabilitation facilities 

  • Navigate the business side of hospital outpatient services and ASCs 

  • Differentiate between inpatient and outpatient services and payment services (IPPS and OPPS) 

  • Understand the difference between MS-DRGs and APC assignments, and how those services are reported 

  • Develop an understanding of compliance in the outpatient hospital facility 

  • Discuss documentation and coding standards for outpatient facilities 

  • Code a wide variety of patient services using CPT®, HCPCS Level II, and ICD-10- CM coding guidelines and code sets 

  • Apply coding and conventions when assigning diagnoses and procedure codes 

  • Understand the UB-04 billing form and its proper use

FAQs: Get your questions answered

How do I become a certified outpatient coder? 

If you want to become a certified outpatient coder, you should complete the COC training course so you can gain all the knowledge and skills needed for the role — and be ready to pass the certification exam. Once you pass the COC exam, you’ll become a certified outpatient coder (COC) — which enhances your credibility and value to employers. 

How much does an outpatient coder make?  

The median income for a COC is $64,267. However, typically the more certifications a person holds, the higher their pay. On average, medical records specialists with three or more AAPC credentials earn $71,361 per year. 

What is the difference between a CPC and a COC? 

The main difference between a CPC and a COC lies in the scope of their job duties and the settings in which they typically work. While CPCs are trained to assign accurate medical codes for both outpatient and inpatient services across various healthcare settings, COCs specialize in outpatient coding for outpatient settings specifically. 

Is outpatient coding easier than inpatient coding? 

Outpatient coding is often perceived as comparatively easier due to the narrower scope of services and more straightforward documentation. Outpatient coding focuses on treatment offered in a single visit, usually lasting only a few hours. Since outpatient visits are short-term, outpatient coding is relatively less complex.
