About MedCodeSearch

What it is

MedCodeSearch is a free lookup and reference tool for three U.S. medical code sets: ICD-10-CM, ICD-10-PCS, HCPCS Level II. Each code page shows the official description, where the code sits in its code set's hierarchy, any official notes attached to it, and the release history of changes to it. Search covers exact codes, partial codes, and plain descriptions.

The site is built directly from official government and CMS source files. It does not re-interpret, summarize with a model, or otherwise alter the wording of an official description or note — see Methodology for exactly how each file is imported and how the site decides what to display.

What it covers

• ICD-10-CM — Diagnosis codes used in U.S. healthcare settings. Maintained by CDC NCHS and CMS, updated annually, effective october 1.
• ICD-10-PCS — Procedure codes used for inpatient hospital procedures. Maintained by CMS, updated annually, effective october 1.
• HCPCS Level II — Codes for products, supplies, drugs, equipment and services maintained by CMS. Maintained by CMS, updated quarterly.

What it does not cover

MedCodeSearch does not include CPT (Current Procedural Terminology) or any other HCPCS Level I codes. CPT is a copyrighted code set licensed by the American Medical Association (AMA), and its terms do not permit republishing the code set the way MedCodeSearch republishes the public-domain government data in ICD-10-CM, ICD-10-PCS, and HCPCS Level II. If you are looking for a CPT code, you will need a licensed source such as the AMA's own CPT products.

ADA CDT dental codes (the D-series that HCPCS Level II defers to the American Dental Association for) are excluded for the same reason. See Data Sources for the specific limitation on each code set.

How it is maintained

The underlying data comes from official release files published by CDC/NCHS and CMS (ICD-10-CM, ICD-10-PCS) and CMS (HCPCS Level II). When a new official release is published, it is imported, validated against the source file, and published as the current release; the release it replaces stays available so you can look up a code as it existed in a prior year or quarter. The import process is described in full on the Methodology page.

MedCodeSearch is operated independently. There is no clinical, coding-certification, or billing staff reviewing individual pages, no advisory board, and no hospital or payer customers — the site's value is in organizing official public data well, not in adding a layer of professional judgment on top of it. If something on the site looks wrong, the Contact page explains how to report it.
