The development of maps between terminologies and classifications will not eliminate administrative coding or the need for expertise in code selection. Fully automating the process of mapping from a reference terminology to a classification system is challenging because of the inherent differences between them. The mapping process is straightforward when the source terminology and the target match up. When more information is needed to express the concept in the target a methodology to bring in contextual information to further refine the map output must be defined.
Problems and diagnoses can be recorded in SNOMED CT in the EHR, while the cross mappings to ICD-10-CM can be used to assist with the reimbursement process. For example: The physician documents that the patient has congestive heart failure using a lexicon linked to SNOMED CT in the problem list. When the HIM coding professional accesses their application to concurrently code the patient’s diagnosis they would see the congestive heart failure entry with the ICD-10-CM code which is mapped to this SNOMED CT concept. The coder could then accept, reject or modify the code list to be used for reimbursement purposes.
Assignment: Create a Mapping Table
Part I: Read about ICD-10 construction in the AHIMA article:
Part II: Go to https://imagic.nlm.nih.gov/imagic/code/map and familiarize yourself with the I-MAGIC (Interactive Map-Assisted Generation of ICD Codes) tool. Create a table to map the following diagnoses from SNOMED to ICD-10-CM. Keep in mind some of the codes may have a one-to-many relationship. Be sure to include any accompanying ICD Notes within your table, for the following diagnoses listed below.
- Acute Respiratory acidosis
- Chronic otitis media; unspecified ear
- Failure to thrive; child
- Fracture of thoracic spine; unspecified
- Nontoxic diffuse goiter
- Essential hypertension
