Best Practices for Using POS Code 22 in Outpatient Facility Claims
Bill POS Code 22 accurately in outpatient facility claims. Follow CMS guidelines, avoid common coding errors, and reduce claim denials fast.
Medical billing is full of small details that carry big consequences. A portion of those details is POS Code 22. For outpatient billing professionals, you’re aware of just how frequently this code appears. You have experienced how upsetting it can be if you have once had a claim denied due to it. From the fundamentals to the specifics of each payer, this article will help you bill with confidence.
What Is POS Code 22 in Medical Billing?
POS stands for Place of Service. Provides the payer with information concerning the location at which the patient received care. An on-campus outpatient hospital setting is identified by the pos code 22. This is where the service took place in a hospital facility but the patient was not admitted to the hospital as an inpatient.
The provider is indicating to the payer that the visit took place in the hospital’s outpatient department by submitting the claim with a POS Code of 22. This is not a private office or a stand-alone clinic. Where the claim occurs has a direct impact on the pricing and payment of the claim. Most commercial payers and Medicare and Medicaid apply the right fee schedule to this code. Doing it right the first time is much more time efficient and will reduce rework.
Why POS Code 22 Matters for Outpatient Claims
The reason POS Code 22 matters so much is simple. Reimbursement rates vary by geographic location. The reimbursement amount for a procedure performed in a hospital outpatient department is usually higher than if the procedure is done in a private office. But there’s a catch to the higher rate; there are tighter regulations.
The Payers are more interested in POS Code 22 claims. They wish to establish that the service actually occurred in an outpatient department of the campus. Even if the code is entered incorrectly, by chance, the claim might be denied or settled for an incorrect amount. It may lead to a compliance review in some instances. For billers, it’s not just a question of getting paid when using POS code 22. It’s all about integrity in billing.
CMS Guidelines for Using POS Code 22 Correctly
There is guidance regarding the use of POS Code 22 from the Centers for Medicare and Medicaid Services (CMS). This code is used when the outpatient service is rendered at a hospital site. It is located on the hospital’s campus and the hospital maintains provider-based status with CMS.
These are the important CMS rules every biller should know:
Provider Based Enrollment: Medicare must enroll the hospital as a PBE (provider-based department). No services performed outside of this enrollment will be paid for with the POS Code 22.
On-Campus Location Requirement: The services must be provided on the main campus of the hospital and not in an off-campus location. Under new rules adopted since the Bipartisan Budget Act of 2015, outpatient departments outside the campus for patients not receiving inpatient care are considered POS 19.
Physician Professional Billing: Physicians reporting professional billing services in a hospital outpatient department should use POS code 22 to specify the location of the service. This will help determine the physician payment rate for the facility or non-facility payment rate.
When unsure, please cross reference the CMS Place of Service Code Set. It is regularly updated and can be found on the CMS website.
Common Mistakes Billers Make With POS Code 22
Billers, even those with a lot of experience, can make mistakes on POS Code 22. If you can, avoiding the most common ones can save you a lot of money.
Billing POS 22 for Off-Campus Locations: One of the biggest mistakes is Billing POS 22 for Off-Campus Locations. If the outpatient department is not part of the main hospital campus then do not use POS Code 22. The wrong code could mean that the payment is the same or more than it should be and it will need to be refunded.
Telehealth Services: Telehealth Service codes have their own set of place of service codes. A virtual visit (POS Code 22) should not be used as a substitute for this.
Failing to Update the Code After a Location Change: When a provider changes locations from an on-campus to an off-campus location, the POS code needs to be updated. A lot of billing teams overlook this when transitioning.
Mismatching Facility and Professional Claims: If both a facility fee and a professional fee are charged, then the POS code must be the same on both claims. Payers get a red flag when there are mismatches.
How POS Code 22 Affects Reimbursement Rates
The most obvious impact of POS Code 22 is in reimbursement. Facility fees are paid under the hospital outpatient prospective payment system (OPPS) under Medicare when the Code 22 is used. In this case, the facility payment rate is lower than the non-facility rate because the overhead is paid by the facility.
The impact is dependent on the contract for commercial payers. There are many commercial plans that are similar to Medicare, but the exact rates will vary depending on the terms of your negotiated contract. That’s why it’s crucial to know the difference between facility and non-facility billing in your contracts. A claim that is marked with an incorrect POS Code may result in the claim being denied as an audit or in under payment of the claim.
POS Code 22 Versus Other Outpatient Facility Codes
It’s useful to view POS Code 22 alongside other codes. A quick comparison:
POS 11 (Office): This is for services provided in a physician’s office that is not part of a medical group. There is no affiliation to any hospital implied. Reimbursement will be based on the non-facility rate.
POS 19 (Off-Campus Outpatient Hospital): This code was added in the 2015 Bipartisan Budget Act to work with the Off-Campus Outpatient Hospital code. It applies to Hospital Out Patient Departments (HOPDs) not located in the main campus. POS 22 is only for on-campus departments.
POS 21 (Inpatient Hospital): Used when a patient is formally admitted. POS 22 is not appropriate here.
POS 23 (Emergency Room): Only applies to services provided in the Emergency Department. The ER is in the same hospital building, but it has a separate code.
Knowing these differences will help ensure POS 22 is used where appropriate.
Documentation Requirements When Billing POS Code 22
Documentation is the key to a successful claim. If you bill your clients with the POS Code 22, you’ll need to have a few items in your records.
Service Location in the Medical Record: Record should verify that the patient was seen in the hospital outpatient department. Notes obtained in a private office visit are not adequate. The date of service, rendering provider and facility location should be well documented.
Separate Documentation for Dual Billing: Hospital charges a facility fee in addition to the professional fee; both fees are to be documented separately. Putting them together in a single note results in confusion and may be a source of denials.
Provider Based Attestation: The hospital should be able to provide a document verifying that the department is a provider based department. This would otherwise put the use of POS Code 22 at risk of challenge during an audit.
Make it a habit to review documentation before submitting. A claim that lacks proper support will struggle to hold up if a payer requests records.
Payer-Specific Rules You Must Know for POS Code 22
Medicare is the base-line but each payer has its own rules. This is where billers must do their research. Several commercial payers do not adhere to Medicare’s OPPS rules. They may charge different amounts of facility and professional fees no matter what the POS Code 22 is. Others need to be authorized to accept the outpatient hospital care setting. Each state has its own Medicaid program and it differs from state to state.
Some state Medicaid programs have their own place of service classifications which may not be entirely consistent with Medicare’s. Check the billing guidelines of the payer before billing. Look for any code-specific policies, documentation requirements or authorization rules. If you have any questions, contact the provider services number of the payer. It takes a few minutes, but can save hours of claims rework.
Real-World Examples of POS Code 22 Usage
Let us look at a few practical scenarios to make this more concrete.
Example 1: A patient comes to an orthopedic surgeon in a hospital owned clinic within the main hospital building at the hospital site. The 99213 is used by the physician with a POS code of 22. A separate facility fee is charged by the hospital. Both statements are true and are properly typed.
Example 2: A cardiologist treats patients at a satellite office, which is 5 miles away from the main hospital. The cardiologist works for the hospital system, but is not on-campus. No, the correct Code is POS 19, not POS Code 22.
Example 3: Physical therapist provides outpatient services in the hospital’s therapy department on the main campus. The facility charges with the UB-04 claim form, under the POS code 22. This is appropriate and supported by CMS guidelines.
These examples demonstrate the proper application of POS Code 22, but not just for employment or affiliation.
Best practices to Avoid Claim Denials With POS Code 22
The price of denials is high in terms of time and money. To reduce them while performing the following actions with POS Code 22:
Confirm Physical Location Prior to Coding: Be sure of the physical location before coding, not based on the employer. When contacting a provider-based department, always double check the exact address from the hospital’s provider-based department list.
Create a Location to Code Reference Sheet: For each location in your facility, assign the appropriate POS code. Modification of locations (additions, changes, and deletions) should be noted on this sheet.
Educate your billing team on On-Campus vs. Off-Campus Rules: One of the most frequent areas for mistakes. Frequent training ensures everyone is on the same page and minimises unnecessary errors.
Run Pre-Submission Edits: Set up billing system edits for claims missing required documentation. Pre-submission is much more cost-effective than denied claims.
Keep up-to-date with CMS changes: CMS regularly updates POS code definitions and if there is a delay in receiving the update, you may experience a ripple effect of unexpected denials.
