Code Description

ICD-10 G44.22 is a billable code used to indicate a diagnosis of chronic tension-type headache.

Key Diagnostic Point:

Chronic tension-type headache (CTTH) is characterized by recurrent episodes of headache that occur on 15 or more days per month on average over a period of at least three months. These headaches are typically bilateral, pressing or tightening in quality, and of mild to moderate intensity. Unlike migraines, CTTH does not usually present with nausea, vomiting, or photophobia. The pain can be exacerbated by stress, fatigue, and poor posture, and may be associated with muscle tightness in the neck and shoulders. The pathophysiology of CTTH is not fully understood, but it is believed to involve a combination of muscle tension, psychological factors, and central sensitization. Diagnosis is primarily clinical, based on patient history and symptomatology, and may require exclusion of other headache disorders. Effective management often includes lifestyle modifications, pharmacological treatments, and preventive strategies aimed at reducing headache frequency and severity.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between tension-type headaches and other headache disorders like migraines.
  • Understanding the chronicity criteria (15 or more days per month).
  • Documenting associated symptoms accurately to avoid misclassification.
  • Recognizing the impact of comorbid conditions such as anxiety and depression.

Audit Risk Factors

  • Inadequate documentation of headache frequency and duration.
  • Failure to differentiate between chronic and episodic tension-type headaches.
  • Misclassification of headache type leading to incorrect coding.
  • Lack of documentation for preventive treatments prescribed.

Frequently Asked Questions

What distinguishes chronic tension-type headache from migraine?

Chronic tension-type headache is characterized by a pressing or tightening sensation without the severe pain, nausea, or aura commonly associated with migraines. It occurs more frequently and is often linked to stress and muscle tension.
