Date of Service in Medical Billing
The date of service (DOS) is the specific date on which healthcare services were provided to a patient.
Date of Service in Medical Billing Explained
In medical billing, the date of service is crucial for claims processing, as it determines the timeframe for submitting claims and ensures that the services are billed for the correct date. Insurance companies use the date of service to verify that services were provided within the policy coverage period.
For example, the date of service for a patient’s doctor’s visit is the day they actually saw the doctor, not the date the bill is submitted.
