Orthopedic ICD-10-CM Codes (FY2026)

792 billable ICD-10-CM diagnosis codes commonly used in orthopedic and spine practices, organized by anatomic region, with official FY2026 descriptions from the CMS ICD-10-CM order file (public domain).

What is in this dataset

Column Description
code ICD-10-CM diagnosis code (billable level)
description Official FY2026 long description from CMS
region Anatomic region: knee, hip, shoulder, spine, hand-wrist, foot-ankle

Region breakdown: spine (246), knee (147), hand-wrist (116), hip (105), shoulder (93), foot-ankle (85).

Source and licensing

Codes and descriptions come from the CMS FY2026 ICD-10-CM order file, which is US government work in the public domain. The orthopedic curation (region mapping and billable-code selection) was done by ClinicFlow, a voice AI company founded by a practicing spine surgeon that handles phone coverage, scheduling, and after-hours triage for orthopedic and spine practices. Released under CC0.

Browsable reference version

A human-friendly, searchable version of this dataset is maintained at:

Related orthopedic practice references: common CPT codes with CMS PFS data, global periods guide, billing modifiers.

Intended uses

Training and evaluating medical coding models, building orthopedic intake or triage tools, EMR integrations, medical billing education, and healthcare NLP experiments that need a clean, region-tagged subset of ICD-10-CM.

Updates

Descriptions follow the CMS fiscal-year cycle (FY2026 as of this release). The browsable version on clinicflowai.com is updated first; this dataset mirrors it.
