The U.S. Department of Health & Human Services (HHS) had been relying on ICD-9, a set of codes, to report diagnoses and in-patient procedures. the ICD-9 code set was replaced by the more detailed ICD-10 code set on October 1, 2015 for healthcare reimbursements, research, and reporting services.
While the physicians had to rely on other partners such as billing services and vendors for previous HIPAA mandates, the use of the new codes requires a deeper level of involvement by the physicians.
There are more than 14,400 different codes in ICD-10 which can be further expanded to over 16,000 codes by using optional sub-classifications. For example, compared to ICD-9-CM, ICD-10-CM codes often capture greater detail on the type of injury. ICD-10-CM and ICD-10-PCS help improve quality measurements and patient safety by providing treatment information and medical process evaluation and outcomes. ICD-10-PCS has the capability to capture new procedures and technologies
