EPISODE NUMBER is the same as attribute ACTIVITY IDENTIFIER and is used to uniquely identify episodes, and is a sequence number for each Consultant Episode (Hospital Provider) in a Hospital Provider Spell. The first episode of each new Hospital Provider Spell (including re-admitted PATIENTS) commences at 01.

A known EPISODE NUMBER can be between 01 to 87.

For other Health Care Provider episodes, it is a sequence number for a CONSULTANT/PATIENT combination; or it is a sequence number for each Sexual Health and HIV Episode.

EPISODE NUMBER is used by the Secondary Uses Service to derive the Healthcare Resource Group 4. Failure to correctly populate this data element is likely to result in an incorrect Healthcare Resource Group, usually associated with lower levels of healthcare resource.
