Key takeaways
- Start with the original publisher.
- Record editions and effective dates.
- Educational explanations supplement official references.
ICD-10-CM: CDC and NCHS
Start with CDC’s ICD-10-CM files page for US clinical-modification releases. Use the official files and guidelines for the relevant edition. The CDC browser is another way to explore official material; always check which release you are viewing.
CPT: the American Medical Association
For CPT, use AMA resources and an appropriately licensed reference. If you are building a product, distinguish access to a learning resource from authorization to include protected content in your own website.
Keep your source notes useful
A source note should identify the publisher, document, edition, effective dates where relevant, and link. Prefer the original publisher over a copied table or unattributed file. Link readers directly to the resource that supports the claim.
Educational sites are supporting resources
An explanatory article can make a subject easier to learn, but it should not replace official coding instructions. HealthivoHub is an independent educational project. It is not affiliated with CDC or AMA and does not provide clinical care or billing services.
Record provenance before trusting a lookup
A reference is easier to verify when it identifies its publisher, edition, release dates, and original source. Store these fields together instead of saving an isolated copied description.
- Diagnosis release files: use the ICD-10-CM hub and FY2027 release guide.
- Protected electronic content: read the CPT licensing checklist.
- Study notes: use the source-aware study worksheet.
