Non-Billable/Non-Specific Code

D3A should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2021 edition of ICD-10-CM D3A became effective on October 1, 2020.
This is the American ICD-10-CM version of D3A - other international versions of ICD-10 D3A may differ.

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. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

code to identify any associated endocrine syndrome, such as:
carcinoid syndrome (
ICD-10-CM Diagnosis Code E34.0
Carcinoid syndrome
Note
- May be used as an additional code to identify functional activity associated with a carcinoid tumor.
E34.0
)

Code Also

Code Also Help

A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.

any associated multiple endocrine neoplasia [MEN] syndromes (
ICD-10-CM Diagnosis Code E31.2
Multiple endocrine neoplasia [MEN] syndromes
Applicable To
- Multiple endocrine adenomatosis
Code Also
- any associated malignancies and other conditions associated with the syndromes
E31.2-
)

Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (D3A) and the excluded code together.

benign pancreatic islet cell tumors (
ICD-10-CM Diagnosis Code D13.7
Benign neoplasm of endocrine pancreas
Applicable To
- Islet cell tumor
- Benign neoplasm of islets of Langerhans
Use Additional
- code to identify any functional activity.

that may be applicable to D3A:

C00-D49
2021 ICD-10-CM Range C00-D49
Neoplasms
Note
- Functional activity
- All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
- Morphology [Histology]
- Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
- Primary malignant neoplasms overlapping site boundaries
- A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
- Malignant neoplasm of ectopic tissue
- Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
Neoplasms

Clinical Information

A benign neoplasm arising from paraganglia located along nerves composed of neoplastic neuroectodermal chromaffin cells.
A paraganglioma that is confined to the site of origin, without metastatic potential.
