Volume depletion (E86)

ICD-10 codes in the E86 category are used to identify various forms of volume depletion, including dehydration and hypovolemia, conditions involving the loss of body fluids or blood volume essential for normal bodily functions.

These codes help healthcare providers specify the reason for fluid loss. For example, E86.0 is the ICD-10 code for dehydration, which includes common terms like "moderate dehydration," "severe dehydration," and "xerostomia due to dehydration." This code covers fluid loss after exertion or insufficient fluid intake. In contrast, E86.1 refers to hypovolemia, a condition marked by decreased plasma or extracellular fluid volume, often causing acute kidney injury or prerenal failure. The term "extracellular fluid volume depletion" also points to this code. When the type of volume depletion isn't specified, E86.9 serves as the catch-all code for unspecified cases. Using these codes accurately ensures proper documentation and treatment planning for fluid and electrolyte imbalances.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

  • codes for any associated disorders of electrolyte and acid-base balance E87

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • dehydration of newborn P74.1
  • postprocedural hypovolemic shock T81.19
  • traumatic hypovolemic shock T79.4

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • hypovolemic shock NOS R57.1

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.

Dehydration

The condition that results from excessive loss of water from a living organism.

Hypovolemia

An abnormally low volume of blood circulating through the body. It may result in hypovolemic shock (see SHOCK).

Intracranial Hypotension

Reduction of CEREBROSPINAL FLUID pressure characterized clinically by ORTHOSTATIC HEADACHE and occasionally by an ABDUCENS NERVE PALSY; HEARING LOSS; NAUSEA; neck stiffness, and other symptoms. This condition may be spontaneous or secondary to CEREBROSPINAL FLUID LEAK; SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)

Shock

A pathological condition manifested by failure to perfuse or oxygenate vital organs.

Xerostomia

Decreased salivary flow.
