K59.00 is a billable diagnosis code used to specify a medical diagnosis of constipation, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like K59.00 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.

Patient Education


Constipation

Constipation means that a person has three or fewer bowel movements in a week. The stool can be hard and dry. Sometimes it is painful to pass. At one time or another, almost everyone gets constipated. In most cases, it lasts a short time and is not serious.

There are many things you can do to prevent constipation. They include

  • Eating more fruits, vegetables and grains, which are high in fiber
  • Drinking plenty of water and other liquids
  • Getting enough exercise
  • Taking time to have a bowel movement when you need to
  • Using laxatives only if your doctor says you should
  • Asking your doctor if medicines you take may cause constipation

It's not important that you have a bowel movement every day. If your bowel habits change, however, check with your doctor.

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.
