Where Can I Download the Official April 2026 ICD-10-CM Tabular XML?

The CDC/NCHS FY2026 April update archive contains icd10cm-April-1-2026-XML.zip. Open that ZIP and select icd10c-tabular-April-1-2026.xml for the Tabular List. The ZIP is a package of multiple XML components, not a single Tabular-only file. The member name begins icd10c, while the ZIP name begins icd10cm; preserve those exact names when searching a saved extraction.

Start from the CDC/NCHS ICD-10-CM files page if a copied direct link stops working. Its FY2026 April section leads to the official April archive. The CMS ICD-10 files page also lists the April 1, 2026 FY2026 diagnosis files and their effective period. These are the publisher and federal program source trails for this particular release.

The April 2026 update is the U.S. ICD-10-CM FY2026 April release, effective for the April 1 through September 30, 2026 period according to CDC/NCHS. It does not turn the entire fiscal year into an April release. Earlier FY2026 work can fall under the October 1, 2025 files; work beginning October 1, 2026 falls under FY2027. Check the applicable service or discharge date and the official instructions for the setting before selecting a file.

For example, a team retaining a source copy for a June 2026 date can label it “U.S. ICD-10-CM FY2026 April update.” A team preparing an October 2026 lookup should open the FY2027 source library instead. This example chooses a release by date; it does not assign a diagnosis code. The October 1 date-boundary guide explains the transition.

We checked the published CDC ZIP on October 27, 2026. Alongside icd10c-tabular-April-1-2026.xml, it contained separate XML files for the disease Index, external-cause Index, drug table and neoplasm table. This matters if a local search returns several “XML” results: the Tabular member is the hierarchy and instruction file; an Index or table answers a different navigation question.

The archive also offers a separately named Table and Index package, code-description files, addenda and guidelines. Do not mistake a description list for the full Tabular hierarchy. A code title or a search excerpt may leave out parent notes, inclusion terms, exclusions and other instructions. Conversely, the Tabular file alone does not replace the Alphabetic Index or the coding guidelines. The official CMS file listing is another way to verify that the selected package is the April update rather than the October FY2026 set.

1. Write the date and classification. Record “U.S. ICD-10-CM diagnosis, FY2026 April update” only when the official April 1–September 30, 2026 period fits the task. This is not the inpatient procedure classification.
2. Enter through the publisher. Open CDC/NCHS files, find the FY2026 April section and follow its archive.
3. Retain the exact package. Save or record icd10cm-April-1-2026-XML.zip, the source URL, publisher and retrieval date. An unexplained local file named “tabular.xml” loses the release context.
4. Inspect the member and related files. Confirm icd10c-tabular-April-1-2026.xml is present. Use the matching Index, complete Tabular entry and applicable official guidelines for a real review.
5. Recheck before reuse. Compare a saved copy with the current CDC/NCHS listing and its effective dates. Do not silently substitute a FY2027 file merely because it is newer.

Our versioned FY2026 April source reference is a convenient navigation aid back to the release. The authoritative files and instructions remain those published by CDC/NCHS and CMS.

Using an October FY2026 ZIP for an April-period question: the year label alone is insufficient because FY2026 has a later April update. Read the file name and effective dates. Looking for a member named icd10cm-tabular: the verified member is icd10c-tabular-April-1-2026.xml. Treating one XML result as a code decision: the complete Index-to-Tabular route, instructions and documentation still need review by a qualified person.

If you are comparing changes rather than obtaining the complete Tabular file, start with the April addenda in the same official archive, then return to the complete entry. The addendum is a change trail, not a substitute for the released classification. For the general lookup sequence, read our Index and Tabular List guide.

This article locates and distinguishes official source files. It does not interpret a patient record, recommend a code, determine sequencing, or predict claim payment. Real-world coding requires qualified review of the documentation, applicable setting, full classification entry and official guidelines. The same file-navigation steps can help a reviewer keep a reproducible source trail without pretending that the download itself resolves a clinical question.
