Quick reference
- When to use
- Use F45.1 when the client has somatic symptoms with disproportionate thoughts, feelings, or behaviors related to those symptoms. The key is the excessive cognitive/behavioral response, NOT whether symptoms are medically explained.
- Duration
- Typically persistent for 6+ months. Reassess periodically. The diagnosis focuses on the psychological response to symptoms, not the symptoms themselves.
- Session codes
- Pair with CPT 90834/90837 for therapy. Coordinate with medical providers. 90791 for evaluation. Consider integrated care models.
- Key indicators
- Somatic symptoms causing distress • Disproportionate health anxiety • Excessive time/energy devoted to symptoms • Functional impairment • Symptoms may or may not be medically explained
What F45.1 represents
SSD focuses on the distressing somatic symptoms PLUS the abnormal thoughts, feelings, and behaviors in response to those symptoms. The symptoms may or may not have a medical explanation – the key is the excessive response.
Key diagnostic criteria
- One or more somatic symptoms that are distressing or result in significant disruption of daily life
- Excessive thoughts, feelings, or behaviors related to symptoms: disproportionate thoughts about seriousness, high anxiety about health, excessive time/energy devoted to symptoms
- State of being symptomatic is persistent (typically 6+ months)
Documentation essentials
Document somatic symptoms, the cognitive/behavioral response, and functional impact. Don't focus on whether symptoms are medically explained.
Differential diagnosis
Distinguish from illness anxiety disorder (minimal somatic symptoms), conversion disorder, factitious disorder, and medical conditions.
Treatment planning
CBT, mindfulness-based approaches, collaborative care with medical providers. Validate symptoms while addressing cognitive distortions.
Insurance & billing
Document both the somatic symptoms and the psychological component. Supports integrated care.
Updates & changes
DSM-5 replaced somatization disorder, pain disorder, and hypochondriasis with SSD and related disorders.
Documentation pitfalls
Don't dismiss physical symptoms. The diagnosis is about the response to symptoms, not the absence of medical explanation.
