DHCS notice (October 9): Medi-Cal clinic institutional claims submitted from October 15 require diagnosis codes
Published November 8, 2026 · Coverage November 1–7, 2026, Pacific · High priority
In a notice published October 9, 2026, DHCS said that for all Medi-Cal claims submitted on or after October 15, 2026, at least one clinically appropriate ICD-10-CM code is required on a UB-04 claim form or the 837I electronic form by Federally Qualified Health Centers (FQHCs), Rural Health Clinics (RHCs), Indian Health Services (IHS) Memorandum of Agreement (MOA) 638 providers and Tribal FQHCs. The trigger is the claim submission date, not a new date-of-service limit, and the notice says updated provider manual sections will be released in a future Medi-Cal Update. First reported in the October 11 edition.
Current status
DHCS's notice was still posted when it was opened in a browser on November 10, 2026, showed no updated date and still said updated provider manual sections will be released in a future Medi-Cal Update. Whether a later notice or the promised manual update has issued was not checked, and current status beyond that notice is unverified.
Who this affects
FQHCs, RHCs, IHS-MOA 638 providers and Tribal FQHCs submitting UB-04 or 837I claims to Medi-Cal, including hospital-affiliated clinics of those types (inference).
Why it matters
Per the October 9 notice, the requirement applies by claim submission date, from October 15, 2026. Inference: a claim from a listed provider type submitted without a qualifying diagnosis code risks rejection or denial.
Required actions
- As the October 9, 2026 DHCS notice states it (later notices and the provider manual update not checked): FQHCs, RHCs, IHS-MOA 638 providers and Tribal FQHCs include at least one clinically appropriate ICD-10-CM code on UB-04 and 837I Medi-Cal claims submitted on or after October 15, 2026. Confirm against any later DHCS notice and the updated provider manual sections.
Recommended action
- Keep the diagnosis edit in affected institutional claim workflows and monitor remittances from October 15.
- Check whether the promised provider manual update has been released, and review it if so.
Implementation playbook
- Check the Medi-Cal provider news page for any later notice on this subject and for the updated provider manual sections, and confirm the requirement still reads as the October 9 notice states it. Owner: Compliance. Due: 2026-11-17.
- Until step 1 is done, apply the October 9 notice as written: confirm the affected provider types and UB-04 and 837I claim queues are identified and the diagnosis edit is live. Owner: Revenue Cycle. Due: 2026-11-17.
- Confirm claims missing a diagnosis code are stopped internally before submission. Owner: IT. Due: 2026-11-17.
- Monitor submissions and remittances, resolve coding exceptions, and reconcile the claim edit to any later notice or manual update. Owner: Coding. Due: 2026-11-20, then monthly.
