Contract Medical Coding Services for Hospitals
Credentialed, U.S.-based coding specialists who clear backlogs, cover staffing gaps, and keep your coding accurate and audit-ready.
Overview
Expert Coding Support, Exactly When You Need It
HMI is a U.S.-based healthcare coding company that gives hospitals and health systems a dependable way to reduce coding backlogs, cover staffing shortages, and sustain accurate, compliant coding day to day. As outsourced medical coding services go, ours is built around one commitment: every engagement is staffed by AHIMA- and/or AAPC-credentialed professionals who code and audit across inpatient, outpatient, ED, ambulatory surgery, and physician settings.
Our specialists are 100% U.S.-based and work fluently in the systems your team already uses — including Epic, Cerner, Meditech, 3M, TruCode, McKesson, Allscripts, NextGen, and eCW. Whether you need short-term overflow help, ongoing contract coding, or ongoing outpatient coding support, our coders work remotely inside your existing workflows instead of asking you to adapt to ours.

Credentialed coders who work remotely to clear a coding backlog, cover staffing shortages, and provide ongoing overflow support — without adding headcount to your team.

Credentials & How We Work
U.S.-Based Coders, AHIMA- and AAPC-Credentialed
Every HMI coder is 100% U.S.-based and holds AHIMA and/or AAPC credentials — RHIT, CCS, CPC, and others — with no coding work sent or subcontracted offshore. Because every person who touches a chart is covered by a single, auditable business associate agreement rather than a cross-border chain of subcontractors, PHI stays easier to track and easier to audit, and protected health information stays with U.S.-based staff under your business associate agreement as a matter of practice.
Engagements follow the same four steps outlined below — scope, onboard, code and review, then educate and sustain — whether you need one contract coder to cover a vacancy or an ongoing coding-quality program across multiple facilities. HMI's own credentialed coders complete every chart themselves, coding remotely inside your existing EHR and encoder rather than asking you to adopt new systems.
Coding doesn't happen in isolation. When a review surfaces compliance risk, our coding compliance audits pick up where coding review leaves off, and if your charge description master needs attention too, we handle that through chargemaster services.
We have been working with HMI since 2010 and have expanded our use of their services to include CDM and ED coding. The HMI coding staff is extremely knowledgeable and has become an integral part of our coding team. We appreciate the professionalism and teamwork we have with HMI.
