Summary Technological development integrated various applications into the healthcare providence and nursing practice to make operations more efficient. Indeed, services that help quickly access crucial data, measure, track, and analyze the processes are valuable for proper differential diagnosis, treatment, and disease management (Warwick et al., 2020). This paper aims to critically appraise the medical application “ICD10 Consult” and assess how it improves healthcare providers’ work and clinical decision-making. Name and Author The medical application selected for a critical appraisal is called ICD10 Consult and is available for most modern mobile devices, desktops, and tablets. The author is Evan Schoenberg, who developed various apps for healthcare assistance and coding. The service is maintained by the creator and operational systems of devices to which ICD10 Consult was downloaded. The application also updates its version every time the ICD10-CM is renewed, and the 2022nd edition of codes, effective from October 1, 2021, has already been uploaded (Centers for Medicare and Medicaid Services, 2021). App Store (2021) states that “The app draws the complete code database directly from the data files available at the Centers for Medicare & Medicaid Services (CMS).” Consequently, ICD10 Consult is a trustworthy service for users who need to search the relevant codes quickly. Endorsement, Operation, and Aesthetics ICD10 Consult provides access to the recent ICD10-CM databases with convenient search and comment tools, and it does not require a governmental agency or administration’s license to retrieve publicly available information. CMS allows application developers to load its data from the website and display it elsewhere, and the relevance of the contents can be checked by a separate search at CMS (Centers for Medicare and Medicaid Services, 2021). ICD10 Consult is developed for mobile platforms where a convenient search can be performed and the results saved as notes or comments. The application is not web-based, and even the desktop version requires downloading the service rather than opening it inside a browser. ICD10 Consult is relatively easy to work with, and navigation allows users to scroll all databases or use a search bar for quicker access to the codes (App Store, 2021). The application can be used without instructions because its aesthetics are simple, and the interface is similar to an online library or catalog. It is beneficial for ICD10 Consult because the users might be of different ages and devices’ use skills. Purpose and Clinical Decision Making ICD10 Consult’s purpose is instant access to all recent ICD10 codes necessary for differential diagnosis, studying diseases, and clarifying the symptoms. ICD10 is an international classification system created and maintained for diagnostic and statistical purposes (Khera, Dorsey, & Krumholz, 2018). The application’s primary users are physicians and healthcare providers for whom the codes are required for clinical decision-making. Indeed, the quickly found results, comments, and notes for further use and the convenience of accessing ICD10 Consult can help choose the proper diagnosis, confirm specific symptoms, or study the epide
