Comorbidities and Complications #7
Description
Records the patient’s pre-existing medical conditions, factors influencing health status, and/or complications during the patient’s hospital stay for the treatment of this cancer using ICD-9-CM codes. All are considered secondary diagnoses.
Rationale
Pre-existing medical conditions, factors influencing health status, and/or complications may affect treatment decisions and influence patient outcomes. Information on comorbidities is used to adjust outcome statistics when evaluating patient survival and other outcomes. Complications may be related to the quality of care.

For complications (ICD-9-CM codes E8700-E8799 and E9300-E9499), there is an assumed decimal point between the fourth and fifth characters. For conditions influencing health status and contact with health services (ICD-9-CM codes V0720-V0739, V1000-V1590, V2220-V2310, V2540, V4400-V4589, and V5041-V5049), there is an assumed decimal point between the third and fourth characters.
