History of Present Illness (HPI)
Under the 95 and 97 Coding Guidelines, HPI coding calculates the number of items selected in each of the HPI sections on templates. When an element is selected, the application assigns a value of 1 to a hidden E&M field corresponding to that section.
The eight HPI hidden E&M fields are as follows:
- loc/rad (em_loc_rad)
- quality (em_qual)
- sev/size (em_sev_size)
- onset (em_onset)
- dur/freq (em_dur_freq)
- context (em_contxt)
- agg/rel (em_agg_rel)
- ass. SX (em_ass_sx)
Each of these eight HPI fields has been mapped to an EM Bullet ID on the E&M Bullets and Field Mapping system template. The EM Bullet IDs are used to total the HPI points using a stored procedure on the Finalize template or on the Coding – OPH template for NextGen® Adaptive Content Engine, 8.4.3 or earlier.
