ICD-10-CM Code D12.1
Benign neoplasm of appendix
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
D12.1 is a billable ICD code used to specify a diagnosis of benign neoplasm of appendix. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code D12 is used to code Adenoma
An adenoma (from Greek αδένας, adeno-, "gland" + -ώμα, -oma, "tumor") (/ˌædᵻˈnoʊmə/; plural adenomas or adenomata /ˌædᵻˈnoʊmᵻtə/) is a benign tumor of epithelial tissue with glandular origin, glandular characteristics, or both. Adenomas can grow from many glandular organs, including the adrenal glands, pituitary gland, thyroid, prostate, and others. Some adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure (as can happen in familial polyposis coli). Although adenomas are benign, over time they may transform to become malignant, at which point they are called adenocarcinomas. Most adenomas do not transform. But even while benign, they have the potential to cause serious health complications by compressing other structures (mass effect) and by producing large amounts of hormones in an unregulated, non-feedback-dependent manner (causing paraneoplastic syndromes). Some adenomas are too small to be seen macroscopically but can still cause clinical symptoms.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code D12.1 and a single ICD9 code, 211.3 is an approximate match for comparison and conversion purposes.
