3. Progress report (1) (1) The Classification Hierarchy which respiratory WG proposed was finalized until 2014. In January-June 2015, discussions with Allergy Working Group (The Joint Allergy Academies) or Pediatric TAG were carried out, and the some revision about the classification hierarchies was carried out. – About “Asthma” “Chronic rhinosinusitis”, “Protracted bacterial bronchitis” (child of “Bronchitis”), 9 tracheal disorders (child of the “Other diseases of upper respiratory tract”), “Embarrassed airway” (child of “Secondary respiratory disorders”), “Respiratory decompensation” (child of “Secondary respiratory disorders”), etc. We proposed some classification hierarchy changes in the proposal platform in 2015. – About “Idiopathic interstitial pneumonia”, “Lipoid pneumonia”, “Peritonsillar abscess” / “Abscess of upper respiratory tract” and “Relapsing polychondritis”. But it seems there are some classification hierarchy needing examination. The representative categories that have problems are as follows (next slide). Has your WG confirmed the hierarchy of the ICD-11 Foundation and Linearization? Have you found any problem with the hierarchy of the Foundation and/or the Joint Linearization for Mortality and Morbidity Statistics in ICD-11 Beta Version?

4. Progress report (1) (2) 1) DA72 Asthma – The Complex Hierarchical Changes Proposal of Asthma has been proposed in our agreement to the Pediatric TAG and the Allergy WG proposal, that is “adding sub classification (‘with exacerbation’ or ‘with status asthmatics’) to the Allergic / Non-allergic asthma, and post- coordinate with severity (mild, moderate, severe) and chronology classifications (Intermittent, Persistent) “. – But, this proposal has not been implemented and we hope this proposal will be implemented. 2) DA37 Peritonsillar abscess / Abscess of upper respiratory tract – The proposal to move “Peritonsillar abscess” to be child of ”Abscess of upper respiratory tract” and the Complex Hierarchical Changes Proposal about “Abscess of upper respiratory tract” have been submitted in the proposal platform. – Respiratory WG agreed with the final Complex Hierarchical Changes Proposal about “Abscess of upper respiratory tract”. But, these proposals have not been implemented.

5. Progress report (1) (3) 3) DA93 Idiopathic interstitial pneumonia (IIPs) – The classification Hierarchy of IIPs is different from the ATS/ERS classification of idiopathic interstitial pneumonias. – We think that this Classification Hierarchy should be the same as the ATS/ERS classification. 4) Inhalational, occupational and environmental lung disease – There are the category “Pneumonitis” as a child of the “Inhalational, occupational and environmental lung disease“. – It is not correct. Because pneumonitis can be also occurred in other causes.

6. Progress report (1) (4) 5) DA16 Vasomotor rhinitis / Allergic and non-allergic rhinitis – The old category "Vasomotor and allergic rhinitis" was changed to the "Allergic and non-allergic rhinitis“ by Allergy Working Group. – However the “Vasomotor rhinitis” has remained at the same level as the "Allergic and non-allergic rhinitis“. It is not correct. – We think that the Classification Hierarchy of the ”Allergic and non-allergic rhinitis” should be revised.

7. Progress report (2) We finished the check and the proposal about the almost definitions in the areas that fall under your WG's responsibility. If there is a definition needing a review, We will correspond. Has your WG completed the input of all definitions in the areas that fall under your WG's responsibility? Do the completed definitions meet the required standards?

8. Progress report (3) 1.When the initial proposal, we proposed based on all ICD-10 entities in the areas under our WG's responsibility. 2.However, after many corrections were carried out, we do not confirm all ICD-10 entities. We check it from now on. In the areas under your WG's responsibility, are all ICD-10 entities able to be mapped to ICD-11?

9. Progress report (4) We have many overlapping entities. However, there is not overlapping entities that have moved to another TAG or WG at present. If there are overlapping entities that have moved to another TAG or WG, has your WG confirmed the move with the other TAG or WG? Or is there a plan to confirm it sometime in the future?

10. Next steps (1) Remaining issuesExpected outcome Some classification hierarchy needing examination For the proposal Issues, we wait for the proposal being implemented, and try to correct in the proposal platform. Correction of the definition in the areas that fall under our WG's responsibility If there is a definition needing a review, We will correspond. Transfer of ICD-10 EntitiesWe check it from now on We wait for instructions from WHO about other work.
