Final answer:
A claim may reject as a non-covered service due to lack of medical necessity, lack of insurance coverage, or if the treatment is experimental or investigational.
Step-by-step explanation:
There are several reasons why a claim may reject as a non-covered service:
- Lack of medical necessity: If a treatment or service is deemed unnecessary for the patient's condition, it may be considered non-covered.
- Lack of insurance coverage: Certain services or treatments may not be covered by the patient's insurance plan.
- Experimental or investigational treatment: Insurance plans generally do not cover treatments that are still in experimental or investigational stages.
