K46.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified abdominal hernia without obstruction or gangrene. The code K46.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code K46.9 might also be used to specify conditions or terms like abdominal hernia as complication of peritoneal dialysis, epiplocele, hernia of abdominal cavity, hernia of body cavity structure, intermuscular hernia , interstitial hernia, etc.
Unspecified diagnosis codes like K46.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

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.

Convert K46.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code K46.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.
There are several types of hernias, including
- Inguinal, in the groin. This is the the most common type.
- Umbilical, around the belly button
- Incisional, through a scar
- Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
- Congenital diaphragmatic, a birth defect that needs surgery
Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.
Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.
