Code: K59.00
Description: Constipation, unspecified
Context: This code is used for cases where a patient is experiencing constipation, but the specific type or underlying cause of the constipation is not specified.
Guidelines for Proper Use
- General Use for Constipation: Employ K59.00 when a patient presents with symptoms of constipation, and the specific type (such as chronic constipation, functional constipation) or cause is not documented or known.
- Accurate Documentation: Ensure that the healthcare provider’s documentation supports a diagnosis of constipation without specifying the exact type or underlying cause. The term “unspecified” should be clear in the medical records.
- Exclusion of Specific Types or Causes: Do not use K59.00 if the patient’s medical record provides a specific type of constipation or identifies an underlying cause (e.g., constipation due to medications, or underlying medical conditions). In such cases, more specific ICD-10 codes should be used.
- Initial Diagnosis: K59.00 can be used as an initial code when constipation is first noted, but should be updated to a more specific code as more information becomes available.
- Compliance with Coding Standards: Utilize K59.00 in line with clinical documentation and adhere to all relevant coding guidelines and payer-specific requirements.
Common Misuses of K59.00
- Application When Specific Type is Known: Misuse occurs when K59.00 is used despite the documentation indicating a specific type of constipation or an identifiable underlying cause. More specific ICD-10 codes should be used in such scenarios.
- Confusion with Related Gastrointestinal Conditions: Avoid using K59.00 for gastrointestinal conditions that may include constipation as a symptom but are distinct clinical entities, such as irritable bowel syndrome or intestinal obstruction.
- Use for Temporary Constipation: Do not use K59.00 for temporary constipation due to situational factors, such as short-term dietary changes or transient medication effects, unless it meets the criteria for a medical diagnosis.
