Disclaimer

Independent reference site — no government affiliation

This website is an independent, commercially operated reference tool. It is not affiliated with, endorsed by, sponsored by, or approved bythe Centers for Medicare & Medicaid Services (CMS), the U.S. Department of Health and Human Services (HHS), the National Center for Health Statistics (NCHS), the American Hospital Association (AHA), or any other government agency or third-party organization. Where official government source data is used, it is cited on our Methodology page — citation does not imply any relationship with the source agency.

Informational use only

Content on this site — including code descriptions, clinical notes, coding guideline summaries, ICD-9-CM crosswalks, and DRG associations — is provided for general informational purposes only. It is not medical advice, coding advice, billing advice, legal advice, or a substitute for the professional judgment of a qualified physician, certified medical coder, health information professional, or attorney.

No warranty

This site is provided "as is" without warranties of any kind, express or implied. We do not guarantee that any code, description, crosswalk mapping, DRG association, or related content is accurate, complete, current, or suitable for a particular clinical, billing, or reimbursement purpose. ICD-9-CM crosswalk mappings in particular are approximate, not one-to-one equivalents, and DRG assignment in practice depends on facts (procedures, complications, discharge status, payer-specific edits) beyond a single diagnosis code — treat both as a starting reference, not a final determination.

You are solely responsible for independently verifying all code selections, crosswalk mappings, and DRG associations against current official CMS/NCHS sources and applicable payer rules before relying on them for any clinical, billing, reimbursement, or legal decision.

Limitation of liability

Use of this site is at your own risk. To the fullest extent permitted by law, we are not liable for any errors, omissions, or outcomes — including financial loss from a billing or reimbursement decision — arising from your use of or reliance on information found on this site. For authoritative, legally binding code sets, always refer directly to the official CMS and NCHS publications.
