CCS Certification (Certified Coding Specialist)
The CCS (Certified Coding Specialist) is AHIMA's advanced credential for hospital inpatient and outpatient coding, covering ICD-10-CM/PCS and CPT. Candidates qualify through coding experience, coursework, or another coding credential, then pass a computer-based exam at a Pearson VUE center. It is widely valued for facility and inpatient coding roles.

What is the CCS certification?
The CCS, Certified Coding Specialist, is AHIMA's advanced credential for facility coding. Where AAPC's CPC centers on physician and outpatient work, the CCS proves mastery of hospital inpatient and outpatient coding, including ICD-10-PCS procedure coding that outpatient coders rarely touch. For a medical coder aiming at hospital work, the CCS is the target credential.
It is generally treated as a more advanced credential than entry-level coding certifications, and it opens higher-paying inpatient roles.
How do you become eligible for the CCS?
AHIMA provides multiple qualifying pathways, so candidates rarely need all of them at once:
- Two years directly applying diagnosis and procedure codes.
- Required coursework plus at least one year of coding experience.
- Another coding credential (such as CPC or AHIMA CCA) plus one year of experience.
- Holding a RHIT or RHIA credential.
Confirm the exact current pathways on AHIMA's site before applying, as eligibility criteria are periodically updated.
What is the CCS exam and why does it pay off?
Example: an outpatient coder with a CPC wants to move into hospital inpatient coding, where pay is higher. Earning the CCS certifies the ICD-10-PCS and inpatient skills that hospital employers require, unlocking roles the CPC alone did not reach.
Frequently asked questions
The CCS, Certified Coding Specialist, is AHIMA's advanced coding credential focused on hospital inpatient and outpatient coding. It tests mastery of ICD-10-CM and ICD-10-PCS plus CPT, and is regarded as a step beyond entry credentials. Facility employers, especially hospitals, prize the CCS for inpatient coding roles.
AHIMA offers several pathways. Common ones include two years of directly applying diagnosis and procedure codes; completing required coursework plus a year of coding experience; or holding another coding credential such as AAPC's CPC or AHIMA's CCA plus a year of experience. Holding an RHIT or RHIA also qualifies you.
It depends on the setting. The CPC (AAPC) is the standard for physician and outpatient coding; the CCS (AHIMA) is the standard for hospital inpatient and facility coding, which generally pays more. Many experienced coders hold both. Choose based on the employers and settings you are targeting.
