Code Description

ICD-10 G44.221 is a billable code used to indicate a diagnosis of chronic tension-type headache, intractable.

Key Diagnostic Point:

Chronic tension-type headache (CTTH) is characterized by recurrent episodes of headache that occur on 15 or more days per month, lasting hours to days. The pain is typically bilateral, pressing or tightening in quality, and of mild to moderate intensity. Intractable CTTH refers to cases that do not respond to standard treatments, significantly impacting the patient's quality of life. Triggers for CTTH can include stress, poor posture, sleep disturbances, and muscle tension. Unlike migraines, CTTH does not typically present with nausea or vomiting, and it is not aggravated by routine physical activity. Preventive treatments may include pharmacological options such as antidepressants, muscle relaxants, and lifestyle modifications aimed at reducing stress and improving posture. Non-pharmacological interventions like cognitive-behavioral therapy, physical therapy, and biofeedback can also be beneficial. Accurate diagnosis and management are crucial, as intractable cases may require a multidisciplinary approach to address both the physical and psychological components of the disorder.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between tension-type headaches and migraines
  • Identifying intractable cases that require specific documentation
  • Understanding the impact of comorbid conditions on headache management
  • Navigating the various treatment options and their documentation requirements

Audit Risk Factors

  • Insufficient documentation of headache frequency and duration
  • Lack of evidence for intractability in treatment notes
  • Failure to document comorbid conditions that may affect treatment
  • Inconsistent use of headache diaries or patient-reported outcomes

Frequently Asked Questions

What distinguishes chronic tension-type headache from other headache types?

Chronic tension-type headache is characterized by its frequency (15 or more days per month) and its non-pulsating, bilateral nature, unlike migraines which are often unilateral and can be accompanied by nausea or aura.
