How Does Insurance Eligibility Verifications and Pre-Authorizations Work

How Does Insurance Eligibility Verifications and Pre-Authorizations Work?

Most claim denials are due to not properly verifying benefit information prior to services being provided. Insurance eligibility verification and prior authorization is the first and vital step in the medical billing process. Insurance verification process is crucial for all encounters, whether inpatient, outpatient or ambulatory care.

It will ensure that the hospital/medical office receives payment for services rendered and will help determine the patient’s share of the hospital’s charges referred to as the patient’s responsibility. Eligibility verification is the process of checking a patient’s active coverage with the insurance company and verifying the authenticity of his or her claims.

To avoid claim rejection, the verification process must be done before the patient is admitted into a hospital, sees a physician or gets services from a medical professional.

Coverage and eligibility benefits should be verified for


all new patients


hospital admissions


any patient who indicates a change to their coverage, and


for all high dollar procedures

Pre-authorization is required for many non-emergency medical procedures and services. Caught between practice administration and patient care, many physicians find it difficult to complete such important tasks on time.

Outsource Strategies International (OSI) can assist physicians and healthcare practices with their insurance eligibility verifications and pre-authorizations.

minimize rejections and denials and


improve bad debt write-off scores


reduce coverage errors

Knowledgeable in each and every aspect of health insurance, healthcare terminologies and medical/surgical techniques, our verification specialists work with payers as well as patients to verify eligibility and obtain authorizations for services or procedures to be provided.

The Best Business Decision I Ever Made!!! I was really frustrated trying to balance patient care and medical billing responsibility. One of my friends who had a good experience with OSI suggested medical billing outsourcing which was not even in my thoughts. I entrusted the medical billing job to OSI and it is the best business decision I have ever made in my career. Joshua Samuel
