ICD-9 |
International Classification of Diseases, 9th Revision. A diagnosis classification coding scheme, managed by HCFA. This is often used as input to the calculation of DRGs and other patient classification schemes. WHO has developed a 10th Revision (ICD-10). |

ICD-9-CM |
ICD-9 Clinical Modification (ICD-9-CM). These are extension to ICD9 procedure codes developed by HCFA for institutional billing. |

ICD-10 |
ICD-10 is much larger than ICD-9. The number of categories available for the classification is significantly enlarged and further detail is available including ambulatory and managed care encounter information, expanded injury codes, the combination diagnosis/symptoms codes to reduce the number of codes needed to fully describe a condition. The new code is six characters long and incorporates common 4th and 5th digit subclassifications. At present (ca. mid 1999) ICD-10 is widely used in Europe. In the U.S., however, migration to ICD-10 is complicated by the fact that ICD-9-CM is embedded in hospital billing systems. The goal is to have ICD-10-CM in use for morbidity diagnoses in 2001. |

Indemnity Health Plan |
Also called fee-for-service, these were the only plans prior to the advent of managed care. With indemnity plans, members pay a pre-determined percentage of the cost of healthcare services, and the insurance carrier pays the rest (e.g., 20/80), after a deductible is met. The fees for services are defined by the providers and vary from one to the next. Members can choose their healthcare providers without restrictions. |

Integrated Healthcare Delivery Network |
An IHDN is an affiliation of healthcare providers (e.g., hospitals, clinics, medical groups). These usually join together to improve performance (e.g., financial, operational) on a broad spectrum of healthcare services. Systems and operations are often consolidated in the process of aggregating these organizations. This allows one institution to offer and coordinate a full spectrum of services, from inpatient acute care facilities to extended care at home. An IHDN can also span the spectrum of formal structures to non-owned groups of providers working together in a less structured arrangement to deliver healthcare. Also called IHN, or IHS. One way or another, an IHDN brings integration and coordination of patient care accross previously independent units. This includes different degrees of vertical and horizontal integration, as well as clinical and operational integration. |
