ICD Coding

Brief description

This is a DSM-5 psychiatric disorder which is manifested by somatic symptoms, (e.g. pain), which must result in significant disruption of daily life. The disorder is present when there are somatic symptoms which cause distress and dysfunction which have insufficient medical rather than psychiatric explanation. This diagnosis is not made if the manifestations are considered part of another psychiatric disorder such as depressive disorder or panic disorder.

Confirming the diagnosis

A report from a specialist psychiatrist that conforms with the Repatriation Commission Guidelines for Psychiatric Compensation Claims is required for diagnosis.

Additional (superseded, non DSM-5) diagnoses that may be covered by SOP
  • Hypochondriasis
  • Pain disorder
  • Somatization disorder
  • Undifferentiated somatoform disorder
Conditions not covered by SOP
  • Other psychiatric disorders such as major depressive disorder which manifest with somatic symptoms
  • Illness anxiety disorder#
  • Conversion disorder# (functional neurological symptom disorder)

# Non-SOP condition

Clinical onset

Clinical onset requires the presence of one or more somatic symptoms that cause distress or psychosocial impairment along with excessive thoughts, worrying, or behaviors (time and energy) related to the somatic symptoms or to health concerns.

Clinical worsening

The condition typically has a chronic fluctuating course.  Eventual improvement or remission can be expected in a significant proportion of subjects. 

 

Psychiatric somatoform classifications:

With the introduction of the DSM-5 there have been significant changes to the somatoform disorders (now called Somatic symptom and related disorders) with the following being the new categories:

  • Somatic symptom disorder. New condition in DSM-5.
  • Illness anxiety disorder (ICD-9 300.7; F45.21). New condition in DSM-5.
  • Conversion disorder (functional neurological symptom disorder) (ICD-9 ; ICD-10 F44.4-7 )
  • Psychological factors affecting other medical conditions (ICD-9 316; ICD-10 F54). Previously present in DSM-IV-TR under ‘Other conditions that may be a focus of clinical attention’.
  • Factitious disorder (ICD-9 300.19; ICD-10 F68.10). Old condition previously in its own chapter of Factitious disorders in DSM-IV-TR but now in somatoform disorder category in DSM-5.
  • Unspecified somatic symptom and related disorder (ICD-9 300.82; ICD-10 F45.9)
  • Other specified somatic symptom and related disorder (ICD-9 300.89; ICD-10 F45.8):
    • Brief somatic symptom disorder
    • Brief illness anxiety disorder
    • Illness anxiety disorder without excessive health-related behaviours
    • Pseudocyesis

The correlation with the previous DSM-IV-TR is imprecise, but the following is provided as a suggested guide (American Psychiatric Association, 2013, ‘Highlights of changes from DSM-IV-TR to DSM-5’, http://www.dsm5.org/Documents/changes%20from%20dsm...)
