What Happened?
Comprehensive Orthopedics & Musculoskeletal Care, LLC was listed in an HHS Office for Civil Rights breach portal report submitted on September 10th, 2026. The incident is classified as a hacking/IT incident involving a network server. According to the HHS filing, 21,897 individuals were affected. No business associate was identified as involved. The specific types of data compromised were not disclosed in the HHS filing or in any publicly available breach notification letter.
The timeline surrounding this incident raises additional questions. Dark web monitoring sources, including Ransomware.live and Breachsense, first identified a listing by the Crypto24 ransomware group claiming Comprehensive Orthopaedics as a victim on or around March 9th–10th, 2026 — approximately six months before the HHS filing date of September 10th, 2026. Crypto24 is a Ransomware-as-a-Service double-extortion group with assessed Eastern European origins that has targeted healthcare, manufacturing, and defense sectors. On its leak site, the group alleged access to HIPAA personal information for over 100,000 people; however, this is an unverified attacker claim and has not been confirmed by the organization. The HHS-reported figure of 21,897 individuals is substantially lower than the attacker’s claim. The organization has not publicly confirmed Crypto24 attribution or disclosed the specific data types involved. Additionally, Mason LLP announced on March 11th, 2026 that it is investigating a class action lawsuit on behalf of affected individuals; as of that announcement, breach notices had not yet been sent. No filed class action complaint has been identified.
