Short Description:Complex regional pain syndrome I (CRPS I)
Long Description:Complex regional pain syndrome I (CRPS I)

Code Classification

  • Diseases of the nervous system (G00–G99)
    • Other disorders of the nervous system (G89-G99)
      • Disorders of autonomic nervous system (G90)

G90.5 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of complex regional pain syndrome i (crps i). The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Complex regional pain syndrome I (CRPS I)

Non-specific codes like G90.5 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for complex regional pain syndrome i (crps i):

  • BILLABLE CODE - Use G90.50 for Complex regional pain syndrome I, unspecified
  • NON-BILLABLE CODE - G90.51 for Complex regional pain syndrome I of upper limb
  • BILLABLE CODE - Use G90.511 for Complex regional pain syndrome I of right upper limb
  • BILLABLE CODE - Use G90.512 for Complex regional pain syndrome I of left upper limb
  • BILLABLE CODE - Use G90.513 for Complex regional pain syndrome I of upper limb, bilateral
  • BILLABLE CODE - Use G90.519 for Complex regional pain syndrome I of unspecified upper limb
  • NON-BILLABLE CODE - G90.52 for Complex regional pain syndrome I of lower limb
  • BILLABLE CODE - Use G90.521 for Complex regional pain syndrome I of right lower limb
  • BILLABLE CODE - Use G90.522 for Complex regional pain syndrome I of left lower limb
  • BILLABLE CODE - Use G90.523 for Complex regional pain syndrome I of lower limb, bilateral
  • BILLABLE CODE - Use G90.529 for Complex regional pain syndrome I of unspecified lower limb
  • BILLABLE CODE - Use G90.59 for Complex regional pain syndrome I of other specified site

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G90.5:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients


Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS) is a chronic pain condition. It causes intense pain, usually in the arms, hands, legs, or feet. It may happen after an injury, either to a nerve or to tissue in the affected area. Rest and time may only make it worse.

Symptoms in the affected area are

The cause of CRPS is unknown. There is no specific diagnostic test. Your doctor will diagnose CRPS based on your signs and symptoms.

There is no cure. It can get worse over time, and may spread to other parts of the body. Occasionally the symptoms go away, either temporarily or for good. Treatment focuses on relieving the pain, and can include medicines, physical therapy, and nerve blocks.
