This code requires a 7th character

The appropriate 7th character is to be added to each code from category T67

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

heat exhaustion due to salt depletion (T67.4)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Heat prostration due to water depletion

Risk adjustment

T67.3 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How T67.3 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to T67.3.

Heat›exhaustion›anhydrotic
Prostration›heat›anhydrotic
Exhaustion, exhaustive›heat›due to›water depletion
Heat›exhaustion›due to›water depletion
Prostration›heat›due to›water depletion

Code to one of these instead T67.3
