Steps to take to make your laboratory coding and billing system pay back more.
In today’s heightened regulatory environment, hospitals place increased emphasis on the accuracy of their charge masters. Additional controls are put in place to assure updates are reviewed and approved by chief financial officers or designees. Significant dollars are spent on consultants to assist in reviewing the charge master.
Ironically, most laboratory billing errors rarely stem from incorrect coding within the charge master. Instead, errors surface when two or more CPT codes appear on patient claims, and these coding combinations are incorrect. Historically, this was the cause of errors with unbundling of multi-channel tests and the fragmentation of reflex tests.
Given this risk, a review of laboratory billing should include an examination of those processes that map multiple CPT code combinations onto patient claims. For laboratory, this includes a review of information systems beginning with order entry and ending with claims generation.
Identify Information Systems
For many hospitals, the billing process encompasses five to seven information systems. Examples include:
* Hospital information system where order entry takes place
* General laboratory information System where hematology and chemistry orders become work in process
* Specialty laboratory systems that manage the unique needs of select services
* Microbiology
* Transfusion medicine
* Anatomic pathology
* Reference laboratory services
* Financial information systems where the charge master resides
* Claims editing systems that edit patient bills to meet specific payor requirements.
Create a list or schematic of these systems.
Determine When Orders Become Charges
Next, identify the exact point in the billing process when orders become charges. For many labs, this occurs at the time of accession when specimens are checked into the lab systems. For others, it may be at time of order. Be aware that microbiology, anatomic pathology and transfusion medicine may have different points of charge capture, so these should be addressed separately.
Look critically at your charge capture architecture. How do charges for add-on orders get captured? If an order is canceled or a specimen remains uncollected, does charging still occur? What checks and balances are in place to monitor the accuracy of charge capture?
Look For Charge Explosion Features
Examine each information system again; locate points where multiple charges may be generated from a single user transaction. This exercise frequently requires an interview with more than one system support analyst. Begin with order entry, identifying order sets or features that facilitate multiple orders with one entry. Typically, this feature is used in the emergency room as a trauma order allowing multiple radiology, cardiology and lab orders to be rapidly placed.
Continue your review with lab systems, identifying order sets, reflex test charges and other automatic charge features. Next, address the financial information system. Look for appended charge and exploded charge features.
Finally, assess the features of each system in the context of the entire process. Are any errors evident?
Re-examine Pricing
As an outcome of your informatics review, you may choose to eliminate entries within charge explosion tables, order sets, appended charges and the like. If so, we suggest examining the impact you changes may have on total charges.
Examine Claims Edits
Once charges are captured, there is another point in hospital billing processes where alterations may occur. This may be in the form of electronic claims editing software or manual transactions performed by business office staff. It is important to identify what does occur. This is typically the point where adjustments are made to multiple chemistry charges or fragmented reflex test charges.
Assess the Outcome of the Billing Process
A detailed review of information systems is not complete with a sample documentation review to validate the outcome of the billing process. Select a sample of patients having a broad array of lab services. Assemble the following documentation for each patient:
1. Copy of physician order 2. Actual test results 3. Detail patient bill 4. UB-92 claim form 5. Remittance advice
If you’ve made specific system modifications, select patients receiving targeted services to determine if new processes are working as intended. You may find that some billing issues stem from physician ordering patterns. Tests may be ordered using old test terminology rather than HCFA approved organ and disease panels. As such, order entry staff must make the translation for them.
A Multidiscipline Approach
Upon completion of an information systems review, you are ready to progress into other distinct billing challenges–concise physician orders, well-documented reflex test protocols and proof of medical necessity. Addressing these challenges requires the commitment of a multidisciplined task force with sponsorship from executive level management. The information system processes will continue to play an integral role, as they must be adapted to the changing needs of the organization.
