Clinical InformationClinical

  • Pancreatic Fistula

    abnormal passage communicating with the pancreas.

  • Exocrine Pancreatic Insufficiency

    a malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (lipase; proteases; and amylase) by the exocrine pancreas into the duodenum. this condition is often associated with cystic fibrosis and with chronic pancreatitis.

  • Pancreas

    a nodular organ in the abdomen that contains a mixture of endocrine glands and exocrine glands. the small endocrine portion consists of the islets of langerhans secreting a number of hormones into the blood stream. the large exocrine portion (exocrine pancreas) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the duodenum.

  • CDAN1 Gene|CDAN1|CDAN1|Congenital Dyserythropoietic Anemia, Type I Gene

    this gene may be involved in nuclear membrane maintenance.

  • CDAN1 wt Allele|CDA-I|CDA1|CDAI|Codanin Gene|Congenital Dyserythropoietic Anemia, Type I wt Allele|DLT|Discs Lost Homolog Gene|Discs Lost, Drosophila, Homolog of Gene|PRO1295|UNQ664/PRO1295

    human cdan1 wild-type allele is located in the vicinity of 15q15.2 and is approximately 14 kb in length. this allele, which encodes codanin-1 protein, may play a role in the maintenance of the nuclear envelope. mutation of the gene is associated with congenital dyserythropoietic anemia type i.

  • Congenital Dyserythropoietic Anemia

    a rare group of disorders that result in anemia that is caused by ineffective erythropoiesis, which is associated with multinuclear erythroblasts, and which may present in childhood. the most common mutations are in the cdan1 and sec23b genes.

  • Congenital Dyserythropoietic Anemia Type II|CDA II|CDAN2|HEMPAS|Hereditary Erythroblastic Multinuclearity with Positive Acidified-Serum Test|SEC23B-CDG

    an autosomal recessive subtype of congenital dyserythropoietic anemia caused by mutation(s) in the sec23b gene, encoding protein transport protein sec23b.

  • Congenital Dyserythropoietic Anemia Type IV|CDAN4

    an autosomal dominant sub-type of congenital dyserythropoietic anemia caused by mutation(s) in the klf1 gene, encoding krueppel-like factor 1.

  • SEC23B wt Allele|CDA-II|CDAII|CDAN2|Congenital Dyserythropoietic Anemia, Type II Gene|HEMPAS|RP11-379J5.1|Sec23 Homolog B (S. cerevisiae) wt Allele

    human sec23b wild-type allele is located in the vicinity of 20p11.23 and is approximately 54 kb in length. this allele, which encodes protein transport protein sec23b, is involved in the transport of vesicles from the endoplasmic reticulum to the golgi. mutation of the gene is associated with congenital dyserythropoietic anemia type ii.

Patient EducationClinical

Pancreatic Diseases

The pancreas is a gland behind your stomach and in front of your spine. It produces juices that help break down food and hormones that help control blood sugar levels. Problems with the pancreas can lead to many health problems. These include:

Questions About K86.89Overview

Is K86.89 (Other specified diseases of pancreas) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified diseases of pancreas on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does K86.89 group to?

When other specified diseases of pancreas is the principal diagnosis on an inpatient stay, it groups to MS-DRG 438, 439, 440, with relative weights from 0.6214 to 1.6302 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of K86.89?

Under the General Equivalence Mappings, other specified diseases of pancreas converts to ICD-9-CM 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.
