Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to D01.5: its own notes plus those printed at D01, block D00-D09, and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Notes
General instructions on how these codes are used.
- 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).

Patient EducationClinical
Bile Duct Cancer
Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.

Questions About D01.5Overview
What is the ICD-10 code for carcinoma in situ of liver, gallbladder and bile ducts?
The ICD-10-CM code for carcinoma in situ of liver, gallbladder and bile ducts is D01.5 (sometimes written as D015). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D01.5 (Carcinoma in situ of other and unspecified digestive organs) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report carcinoma in situ of liver, gallbladder and bile ducts on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D01.5 group to?
When carcinoma in situ of liver, gallbladder and bile ducts is the principal diagnosis on an inpatient stay, it groups to MS-DRG 436, 437, 435, with relative weights from 0.8078 to 1.8428 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D01.5 be reported with a code from D03?
Not as a rule. The Excludes1 note at D01, which applies to D01.5, lists "melanoma in situ (D03.-)". 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).
What is the ICD-9 equivalent of D01.5?
Under the General Equivalence Mappings, carcinoma in situ of liver, gallbladder and bile ducts converts to ICD-9-CM 230.8 (ca in situ liver/biliary). The mapping is a direct match.
