Wednesday, October 1st, 2025. Week 40.   SYNGAP1 Related Disorders secured an ICD-10 code exactly four years ago today, through the advocacy of SRF and the hard work of volunteers like Hans Schlecht.  Our code is F78.A1 Blog: https://curesyngap1.org/blog/syngap1-assigned-its-own-icd-10-code-f78-a1-srf/ Check out #S10e8 to learn more: https://www.youtube.com/watch?v=tZ5s5rQawXg Read the case study: https://everylifefoundation.org/icd-code-roadmap/#toggle-id-13 Hear from other leaders: https://effieparks.com/podcast/episode-224-the-complicated-world-of-icd10-codes-with-ceo-and-co-founder-of-slc6a1-connect-amber-freed   Why does it matter and where are we now?  It helps us find patients and it helps doctors and companies find YOU.  We  aren’t where we should be.   Dr. Lal’s sobering post: https://www.linkedin.com/posts/dennis-lal-71a8988a_raredisease-epilepsy-precisionmedicine-activity-7373307411383857152-dQS0   Preprint: https://www.medrxiv.org/content/10.1101/2025.09.12.25335652v1.full.pdf   TABLE 1.

In our cohort, fewer than two-thirds of eligible patients were ever documented with their syndrome-specific ICD-10 code, and when used, these codes were applied inconsistently across encounters, specialties, and time. Such gaps hinder the reliable identification of patients for precision therapies, clinical trials, and research studies, limiting the intended value of these codes. Although uptake of syndrome-specific ICD-10 codes showed gradual improvement over time, additional efforts, including automated and patient-driven coding support and integration of structured genetic data, are needed to ensure accurate and consistent use. Broader, multi-institutional studies will be essential to validate these findings and to guide strategies that maximize the clinical and research utility of syndrome-specific ICD codes as precision medicine advances.   Who else got them?  New DEE Codes effective 10/1/2025! https://www.cdc.gov/nchs/icd/icd-10-cm/files.html #FOXG1 Q04.8 https://www.foxg1research.org/news/foxg1-syndrome-icd-10-code #Kabuki Q87.0 #USP7 Q87.87 https://www.linkedin.com/posts/foundation-for-usp7-related-diseases_were-proud-to-share-an-important-milestone-activity-7375555189539348480-77n3  #CTNNB1 Q87.88 https://www.linkedin.com/posts/ctnnb1_ctnnb1-connectandcure-ctnnb1syndrome-activity-7376633308836683777-fRYC  #SCN2A QA0.0101 https://www.scn2a.org/from-advocacy-to-action-scn2a-now-has-its-own-icd-10-code/ #CACNA1A QA0.0102 https://www.linkedin.com/posts/cacna1a-foundation_huge-milestone-for-our-cacna1a-community-activity-7358883822282653696-xWr5  #SLC6A1 QA0.0131 https://www.linkedin.com/posts/slc6a1connect_raredisease-icd10-genetics-activity-7374801222056411136-wmAZ #STXBP1 QA0.0141 https://www.stxbp1disorders.org/news/stxbp1-has-an-icd-10-code  #DLG4 QA0.0149 #Usher H35.5   CombinedBRAIN Rent a Neuro: https://combinedbrain.org/rent-a-neuroscientist/   CB Slide on ICD-10: https://docs.google.com/presentation/d/1wys1RLbJWBtK9eh7xSd_Lm-xwqbeZMSnM7xcCQznE8M/edit?usp=sharing    Everylife Roadmap: https://everylifef
