What Does the Term CO Means?
In medical billing, the term "CO" is an abbreviation for "Contractual Obligation." CO codes are used to identify instances where a healthcare claim has been denied or adjusted based on a contractual agreement between the healthcare provider and the insurance company or other payer.
These contractual agreements can relate to things like the maximum allowable fee for a particular service, specific coverage criteria or exclusions, and other terms and conditions that apply to the payment of healthcare claims.
CO codes are just one type of denial or adjustment code used in medical billing, and they serve as an important way for healthcare providers and insurance companies to communicate about the payment of healthcare claims and ensure that they are in compliance with their contractual obligations.
Most Common Contractual Obligations
There are several common contractual obligations that may lead to the use of CO codes in medical billing. Here are a few examples:
- Maximum allowable fee: Many insurance companies and other payers have a maximum allowable fee that they will pay for a particular service. If a healthcare provider charges more than this maximum fee, the claim may be denied or adjusted with a CO code.
- Covered services: Insurance companies often have specific criteria for which services they will cover and under what circumstances. If a service does not meet these criteria, the claim may be denied or adjusted with a CO code.
- Exclusions: Insurance companies may also have specific exclusions for certain services or conditions that are not covered under their policies. If a healthcare provider submits a claim for a service or condition that is excluded, the claim may be denied or adjusted with a CO code.
