Help For HealthCare: Mapping Unstructured Clinical Notes To ICD-10 Coding Schemes

Photo of Amit ShethThe health care industry – and the American citizenry at large – has been focused of late on the problems surrounding the implementation of the Affordable Care Act, the federal website’s issues foremost among them. But believe it or not, there are other things the healthcare industry needs to prepare for, among them the October 1, 2014 date for replacing the World Health Organization’s International Statistical Classification of Diseases and Related Health Problems ICD-9 code sets used to report medical diagnoses and inpatient procedures by ICD-10 code sets. ICD-9 uses 14,000 diagnosis codes which will increase to 68,000 in ICD-10, which is a HIPAA (Health Insurance Portability and Accountability Act) code set requirement.

Natural language processing has had the primary role in many solutions aimed at transforming large volumes of unstructured clinical data into information that healthcare IT application vendors and their hospital customers can leverage. But there’s an argument being made that understanding unstructured text of clinical notes that contain a huge stash of information and then mapping them to fine-grained ICD-10 coding schemes requires a combination of NLP, advanced linguistics, machine learning and semantic web technologies, and Amit Sheth, professor of computer science and engineering at Wright State University and director of the Kno.e.sis Center is making them. (See our story yesterday for a look at how the NLP market is evolving overall, including in healthcare.)

“ICD-10 has thousands of codes with millions of possible permutations and combinations. A rule-based approach is not effective to cover the huge number of ICD-10 codes.” Sheth says. Extracting the correct concepts, identifying the relationship between these concepts and mapping them to the correct code is a major challenge, with codes often formed by information from various sections of a clinical document that itself is subject to individual physicians’ style of recording information, among other factors.

A Closer Look At SemTechBiz Startup Competition Winner: KnowMED And Its Clinical Discovery Platform

KnowMED walked away the big winner of the Semantic Start-Up Competition. The Semantic Web Blog caught up with CTO Matthew Vagnoni, MS, and CEO Jerry D. Scott to further discuss the company’s winning entry, the Clinical Discovery Platform, for helping the health care sector semantically integrate data and ask natural language questions of that data, to support clinical research and complex decision-making.

The problem that the health care industry at large faces of not being able to easily and efficiently integrate and share data across organizations’ borders is equally a challenge right within the institutions themselves. “Large modern health care organizations are somewhat insular,” says Vagnoni.

At Medical City Children’s Hospital in Dallas, as an example, there are three separate electronic health record systems just for its neonatal division. The diverse formats and vocabularies made it difficult to try to ask questions of this data for research or efficiency purposes. But within two months of deploying KnowMED’s Clinical Discovery Platform, Vagnoni says, most of the data was integrated into a single view, “so clinicians could interact with it almost like using Google. …We combined the data from all the different sources so that clinicians could go in and ask questions [that reflect] how they think, not how [the information] is in the data schema.”
