Clinical Classification

Clinical Information

  • Hirschsprung Disease

    congenital megacolon resulting from the absence of ganglion cells (aganglionosis) in a distal segment of the large intestine. the aganglionic segment is permanently contracted thus causing dilatation proximal to it. in most cases, the aganglionic segment is within the rectum and sigmoid colon.
  • Megacolon

    dilatation of the colon, often to alarming dimensions. there are various types of megacolon including congenital megacolon in hirschsprung disease, idiopathic megacolon in constipation, and toxic megacolon.
  • Megacolon, Toxic

    an acute form of megacolon, severe pathological dilatation of the colon. it is associated with clinical conditions such as ulcerative colitis; crohn disease; amebic dysentery; or clostridium enterocolitis.
  • Hirschsprung Disease|Aganglionic Megacolon|Hirschsprung's Disease|Hirschsprung's Disease

    a congenital disorder characterized by the absence of myenteric ganglion cells in the distal colon. it results in a functional stenosis of the distal colon and a massive distention of the proximal colon.
  • Megacolon

    an abnormal dilation of the colon not due to obstruction.
  • SOX10 wt Allele|DOM|Dominant Megacolon, Mouse, Human Homolog of Gene|PCWH|RP5-1039K5.9|SRY (Sex Determining Region Y)-Box 10 wt Allele|SRY-Related HMG-Box Gene 10|WS2E|WS4|WS4C

    human sox10 wild-type allele is located in the vicinity of 22q13.1 and is approximately 17 kb in length. this allele, which encodes transcription factor sox-10 protein, plays a role in transcriptional activation. mutation of the gene is associated with waardenburg syndrome types 2e and 4c and with peripheral demyelinating neuropathy, central dysmyelinating leukodystrophy, waardenburg syndrome, and hirschsprung disease.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Megacolon NOS

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Replacement Code

K5939 replaces the following previously assigned ICD-10-CM code(s):

  • K59.3 - Megacolon, not elsewhere classified

Convert K59.39 to ICD-9-CM

  • ICD-9-CM Code: 564.7 - Megacolon NEC
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

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.
