Final answer:
A health services coordinator needs to use a Current Procedural Terminology (CPT) code in conjunction with the ICD-10 code when reporting outpatient treatment for reimbursement by an insurance company.
Step-by-step explanation:
When reporting an ICD-10 code for reimbursement for outpatient treatment, a health services coordinator needs to use another type of code in conjunction with the ICD-10 code. This additional code is called the Current Procedural Terminology (CPT) code. The CPT code is used to describe the specific procedures or services provided during the outpatient treatment. It helps insurance companies determine the appropriate reimbursement amount for the treatment rendered by the provider.
