Hospital Billing vs. Clinical Billing

Two kinds of billing exist in the medical billing genre – Hospital billing (institutional billing) and clinical billing (physician billing). Hospital billing refers to the billing of claims generated for services performed by doctors who are associated with a hospital and for patients that make use of outpatient/inpatient services, diagnostic procedures, emergency services, laboratory, medication, oxygen services, several therapies, and radiology services.

Clinical billing refers to the billing of claims generated for the services performed by individual physicians which include lab tests, procedures, and minor surgeries, and by other non-institutional providers to a patient.

Factors that differentiate both the billing systems are:

1. Billing and Coding:

Physicians typically work with one medical billing professional for billing and coding purposes. A primary reason is that working with several billing professionals would lead to chaos and the questioning by insurance providers on claims would create confusion along with taking a longer turnaround time on reimbursements.

A single window would also lead to a reduction in errors as a single billing expert would be able to give more time to detect and rectify mistakes if any.

2. Processing time:

As a physician is mobile in their services, they prefer to record all their details in one area rather than asking the hospital’s billing department to do the same which could take longer for processing. The insurance industry is also well versed with people who are experts themselves in hospital and clinical billing.

Also, physicians see lesser patients than a hospital. Hence, the independent physician prefers billing separately as this not only speeds up the process, it creates lesser hurdles and increases the turnaround time for reimbursements. For hospitals, the insurance company works as per the hospitals’ norms which could delay a physician’s bill (who works with a hospital).

And as a hospital has investors and operating capital, they can wait for the claim to come through, whereas independent practitioners wouldn’t want to. Medical Billers and coders are two different entities in hospitals. For independent physicians, it is usually one biller with physicians sometimes doing the coding themselves.

3. Form:

Clinical billing is usually prepared on a CMS-1500 form. It’s a claim form consisting of red ink on white paper and is used by suppliers and physicians. The electronic version of the form that is accepted by Medicare, Medicaid, and other insurance providers is known as 837-P where P implies the professional format.

Institutional or hospital billing is usually prepared on a UB-04 (Universal Bill). It is a similar colored form and the electronic version is known as 837-I where I stand for institutional billing.

4. R&C:

Both are paid according to a reasonable and customary (R&C) amount. In the case of clinical billing, this amount is based on aggregate data from multiple insurers whereas in hospital billing, this amount is based on industry data or by the mutual contract formed between the hospital and the insurance provider.

All in all, whether Hospital Billing or clinical, both have their specific demands that either make it more simple or complicated. And hence, medical billing on a whole needs professionals who continuously keep abreast with the ongoing trends and regulations.

FAQs:

1. What is the main difference between hospital billing and clinical billing?

Hospital billing refers to claims for services performed in a hospital setting, while clinical billing pertains to services provided by individual physicians or non-institutional providers.

2. What forms are used for clinical and hospital billing?

Clinical billing typically uses the CMS-1500 form for claims, while hospital billing employs the UB-04 form. Their electronic versions are known as 837-P and 837-I, respectively.

3. How does the processing time differ between hospital and clinical billing?

Clinical billing often has a faster processing time since physicians handle it directly, whereas hospital billing may be slower due to additional layers of administration and protocols.

4. Why is a single billing professional preferred in clinical billing?

Working with one billing professional reduces errors and confusion, streamlining the process and allowing for quicker claim resolution and reimbursements.

5. How are payments determined for hospital and clinical billing?

Payments for both types of billing are based on reasonable and customary (R&C) amounts, but clinical billing is determined by aggregate data from multiple insurers, while hospital billing is based on industry data or contracts with insurers.
