ICD-10-CM Code E35

Valid for Submission

E35 is a billable code used to specify a medical diagnosis of disorders of endocrine glands in diseases classified elsewhere. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code E35 might also be used to specify conditions or terms like endocrine infection.

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code E35:

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

• underlying disease, such as:
• late congenital syphilis of thymus gland Dubois disease A50.5

Use Additional Code

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.

• code, if applicable, to identify:
• sequelae of tuberculosis of other organs B90.8

Type 1 Excludes

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.

• Echinococcus granulosus infection of thyroid gland B67.3
• meningococcal hemorrhagic adrenalitis A39.1
• syphilis of endocrine gland A52.79
• tuberculosis of adrenal gland, except calcification A18.7
• tuberculosis of endocrine gland NEC A18.82
• tuberculosis of thyroid gland A18.81
• Waterhouse-Friderichsen syndrome A39.1

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code E35 are found in the index:

• - Calcification
  • - adrenal (capsule) (gland) - E27.49
    • - tuberculous - E35

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

• Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.

Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Endocrine infection
