CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

E86 is a non-billable ICD-10-CM category code for volume depletion, so it cannot be submitted on claims. Use a more specific code from this category instead, such as E86.0, E86.1, and E86.9.

Specific Coding for Volume depletionOverview

Non-specific codes like E86 require more characters. Use one of these billable codes instead:

  • Use E86.0 for Dehydration

  • Use E86.1 for Hypovolemia

  • Use E86.9 for Volume depletion, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to E86: its own notes plus those printed at block E70-E88 and Chapter 4. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On E86 itself
  • dehydration of newborn (P74.1)
  • postprocedural hypovolemic shock (T81.19)
  • traumatic hypovolemic shock (T79.4)
From Block E70-E88 Metabolic disorders applies to 286 codes
  • androgen insensitivity syndrome (E34.5-)
  • congenital adrenal hyperplasia (E25.0)
  • hemolytic anemias attributable to enzyme disorders (D55.-)
  • Marfan syndrome (Q87.4-)
  • 5-alpha-reductase deficiency (E29.1)
From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On E86 itself
  • hypovolemic shock NOS (R57.1)
From Block E70-E88 Metabolic disorders applies to 286 codes
  • Ehlers-Danlos syndromes (Q79.6-)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code(s) for any associated disorders of electrolyte and acid-base balance (E87.-)

Notes

General instructions on how these codes are used.

From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Excludes2 2

These codes carry an Excludes2 note naming E86: its condition is not part of those codes, and both may be reported when the patient has both.

  • R79.1 Abnormal coagulation profile
    abnormality of fluid, electrolyte or acid-base balance (E86-E87)
  • Block T80-T88 Complications of surgical and medical care, not elsewhere classified
    disorders of fluid and electrolyte imbalance (E86-E87)

Patient EducationClinical

Fluid and Electrolyte Balance

Electrolytes are minerals that have an electric charge when they are dissolved in water or body fluids, including blood. The electric charge can be positive or negative. You have electrolytes in your blood, urine (pee), tissues, and other body fluids.

Questions About E86Overview

What is the ICD-10 code for volume depletion?

E86 is the ICD-10-CM category for volume depletion, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E86 (Volume depletion) a billable code?

No. This is a category header that groups the codes for volume depletion, and headers cannot be submitted on claims. Claims for volume depletion need a more specific code from this category, such as E86.0, E86.1, and E86.9.

Can E86 be reported with P74.1?

Not as a rule. The Excludes1 note on E86 lists "dehydration of newborn (P74.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does E86 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code(s) for any associated disorders of electrolyte and acid-base balance (E87.-). The additional code is reported after E86.
