How ICD FINDER works

What the finder is, where the codes come from, how rules are shown, and what to keep in mind.

What is ICD FINDER

ICD FINDER lets you browse and search every ICD-10-CM diagnosis code, from the 22 chapters down to the most specific code, with the rules that apply to each.

It is built for analysts, researchers and anyone who works with diagnosis codes and needs a quick, sourced answer to "what does this code cover, and what can or cannot be coded with it?"

The finder shows the official list. It does not tell you which code to choose. See Limits.

Data

  • Source: the ICD-10-CM 2027 Tabular List of Diseases and Injuries, published by the US Centers for Disease Control and Prevention and the Centers for Medicare & Medicaid Services (CDC/CMS).
  • Coverage: all 22 chapters, 297 code groups and 47,322 headings and codes, of which 36,449 are complete codes.
  • Official wording: descriptions and rules are the CDC/CMS text, not reworded. Chapters also show a short everyday name, such as Cancer, added to make them quicker to scan. These short names are not part of ICD-10-CM.
  • Updated every year when CDC/CMS publish a new list.
  • Private: no account, and nothing you type is sent anywhere.

How to use

  1. Browse: press a chapter to see its code groups, and a code group to see its codes.
  2. Search: type a code, a condition or any word from the rules. Pick a result from the list.
  3. Read a code: the details show the full path from the chapter down, the neighbouring codes and every rule that applies.
  4. Share: the page address holds the code, so you can send a link to a colleague.

Reading the rules

  • Inclusion terms are wordings the list says are coded here. They belong to that one code.
  • Excludes1: the other condition is never coded together with this one.
  • Excludes2: the other condition is not part of this one, but both can be coded together.
  • Use additional code, Code first and Code also are shown as written.
  • Rules carry down. A rule written on a chapter, a code group or a code applies to every code beneath it. It is shown on each of them, with where it was written.
  • Complete code means no more specific code sits beneath it. Other codes are marked Has more specific codes.
  • Codes named in a rule, such as (E10.-), are links. A trailing dash means the code is not complete and needs more characters.

Limits

  • The Tabular List only. The Alphabetic Index, synonyms and clinical notes from other sources are not included.
  • Not coding advice. Coding guidelines, payer rules and the dates a code is valid from are outside this page, so check them before you assign a code.
  • One year. This is the 2027 list, and codes from other years can differ.
  • Diagnosis codes only. ICD-10-PCS procedure codes are a different list.
