- syphilitic pancreas A52.74
- tuberculosis of gallbladder A18.83

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.
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.

Bile Duct Diseases
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 K87Overview
Is K87 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does K87 group to?
On inpatient claims, disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere maps to MS-DRG 444, 445, 446, with relative weights from 0.8273 to 1.6709 depending on complications. Higher weights mean higher Medicare reimbursement.
Can K87 be a principal diagnosis?
No. This is a manifestation code: disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
What is the ICD-9 equivalent of K87?
Under the General Equivalence Mappings, disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere converts to ICD-9-CM 576.8 (dis of biliary tract NEC) and 577.8 (pancreatic disease NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
