Effects of other deprivation (T73)
The ICD-10 code section T73 covers the effects of various forms of deprivation, including starvation, water deprivation, and exhaustion due to exposure or excessive exertion. These codes are used to classify conditions resulting from a lack of essential resources or extreme environmental stresses.
This section includes specific codes such as T73.0 for starvation (also described as deprivation of food or starvation-related malnutrition), T73.1 for deprivation of water, and T73.2 and T73.3 for exhaustion caused by environmental exposure or excessive physical exertion, respectively. For example, the ICD-10 code for starvation (starvation, anemia due to starvation, or starvation ketoacidosis) helps identify acute or ongoing cases, with distinctions for initial, subsequent, or sequela encounters using seventh-character extensions like T73.0XXA or T73.0XXS. These codes assist medical coders and healthcare providers in documenting and tracking health impacts due to critical resource shortages, overexertion, or environmental extremes.
Additionally, T73.8 captures other effects of deprivation that do not fall under starvation or exhaustion, while T73.9 is used when the specific deprivation effect is unspecified. This detailed categorization enables accurate reporting of similar but distinct clinical conditions under the broader heading "Effects of other deprivation."

Instructional Notations
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category T73
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Refeeding Syndrome
A condition of metabolic imbalance that is caused by complications of initially feeding a severely malnourished patient too aggressively. Usually occurring within the first 5 days of refeeding, this syndrome is characterized by WATER-ELECTROLYTE IMBALANCE; GLUCOSE INTOLERANCE; CARDIAC ARRHYTHMIAS; and DIARRHEA.
Starvation
Lengthy and continuous deprivation of food. (Stedman, 25th ed)
