Health Claims Processing Workflow
Prepared by
Laurence J. Best (American Management Systems,
Inc.)
Background

Use Cases
Background
A health claims processing organization is commissioning a system
that routes work between the various components of its health claims
processing operation. Such organizations, found throughout the world,
reimburse health care providers (e.g., doctors and hospitals) for
medical treatment. These organizations are sometimes government
agencies and sometimes insurance companies. There is often a
requirement for insurance company processing even in countries with
socialized medicine; for example, Canada's national health care
system does not encompass routine dental and vision care.
The workflow system to be created routes work objects (in this
case, health claims and supporting documentation) among the major
processing components of the organization. Some of these processing
components are highly automated, while others require quite a bit of
human judgment, but all components have some level of computer system
support. It is not the objective of the new workflow system to
replace any existing components, but rather to improve the overall
movement of claims through these components.
The major components of the particular health claim processing
operation that will be linked by the new workflow routing system are
as follows:
- Receipt processing. This consists of various systems
which receive health claims and supporting documents via a variety
of different sources. Claims are received electronically, for
example, from claims clearing houses, Health Maintenance
Organizations, and some physicians. They are also received
"electronically" via Fax. Finally, paper claims are received via
mail. All are logged by assigning a unique identifier. Paper
claims and supporting documents are scanned.
- OCR. Scanned paper claims and fax files are processed
via an ICR (Intelligent Character Recognition) process to
determine what kind of document it is. Each document is then
subjected to form dropout whereby standard form lines are
eliminated), deskewing (to right the image), and despeckling (to
eliminate random scan errors). The image is then run through an
OCR (Optical Character Recognition) process to capture the data
associated with each form field.
- Repair and committal. Fields with sufficiently low
confidence levels are subjected to a manual repair data entry
process. If necessary, the document is rescanned. In addition,
certain types of claims images that cannot be processed by OCR are
transmitted to an offshore data entry vendor (for example, in the
Dominican Republic or Barbados) for keying, and keyed data
transmitted back. Finally, all images are committed to optical
disk and logged into an index database, and claim data loaded to a
mainframe-based claims payment system.
- Provider/Plan match. An automated process continually
attempts to match the plan (i.e., the contract under which the
claim is being paid) and the health care provider (i.e., the
doctor) identified on the claim with the providers with which the
overall claim processing organization has a contract. If there is
not an exact match, the program identifies the most likely matches
based on soundex technology. The system displays prospective
matches to knowledge workers in order of the likelihood of the
match, who then identify the correct provider.
- Auto adjudication. The claim payment system determines
whether a claim can be paid, and how much to pay, if there are no
inconsistencies between six key data items associated with the
claim. If there are inconsistencies, the system "pends" (i.e.,
suspends) the claim for processing by the appropriate claims
adjudicator, depending on a number of factors including the plan
type, the type of treatment involved, and the amount of work in
each adjudicator's work queue.
- Adjudication of pended claims. The adjudicator can
access the mainframe system for a claim history or the image
system for an image or, for electronic claims, a fabricated
representation of the original claim. The adjudicator either
approves the claim for payment, specifying the proper amount to
pay, generates correspondence requesting additional or clarifying
information, or generates correspondence denying the claim. Text
processing is supported via link to a standard word processing
package.
The Design Problem
Design a work routing system that routes health claims through the
various stages of the adjudication process. The major
responsibilities of the system are to:
- account for work objects at all times (ensuring that all are
processed on a timely basis),
- present work performers (the workers and information systems
involved with the process) with work objects at the earliest
appropriate time,
- inform process managers of process anomalies,
- provide a means for process managers to adjust the work
process, and
- provide management information on the overall work process.
The system must not "hard code" routing rules; instead, it must
provide the means for initially defining a "default" work process,
with the capability of adjusting this process for individual items
should the need arise.
Use Cases
Use Case #1: Adjudicator selection of next work item
The adjudicator retrieves items from the work queue on either a
"pull" basis by selecting a particular claim (perhaps based on
special instructions from a supervisor) or a "push" basis, by having
the workflow system provide the most appropriate claim to process
next, based on a work prioritization algorithm. This work
prioritization algorithm is not "hard-coded;" the workflow system
provides a means for the system administrator to define and modify
this algorithm. (Note - designing the facility for defining the work
prioritization algorithm is outside of the scope of this exercise).
Use Case #2: Process management
The process manager modifies routing rules for a Dental claims,
one of a number of claim types. The new rules are largely based on
the "default" process for all claims, with certain processing
differences. The process manager has the option of having the new
routing rules apply only to newly received claims, or to claims
already being processed. The system automatically identifies any
claims that have reached a state under the old process that is
inconsistent with the new process.
Use Case #3: Work item reconcilement
The system administrator access the workflow system to determine
whether all work objects are accounted for. The workflow system
reconciles the system based on counts of the number of work objects
outstanding in the various stages of the process as of the last
synchronization point (midnight local time), the number of work
objects received since that point, and the number completed since
that point.
