What is the ICD-10 code for reflex sympathetic dystrophy?

The ICD-10 code for reflex sympathetic dystrophy, also known as CRPS Type 1, is G90.5- with specific codes for different limbs.

How do you code CRPS Type 1?

CRPS Type 1 is coded as G90.50 for unspecified sites, G90.51 for upper limb, and G90.52 for lower limb, depending on the affected area.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
G90.50	Complex regional pain syndrome I, unspecified	Use when the location of CRPS Type 1 is unspecified.	Persistent burning pain with allodynia No major nerve injury At least one sign such as edema or temperature asymmetry
G90.51	Complex regional pain syndrome I of upper limb	Use for CRPS Type 1 affecting the upper limb.	Persistent burning pain in upper limb Temperature asymmetry documented by thermography No major nerve injury
G90.52	Complex regional pain syndrome I of lower limb	Use for CRPS Type 1 affecting the lower limb.	Persistent burning pain in lower limb Temperature asymmetry documented by thermography No major nerve injury

Documentation & Coding Risks

Avoid these common issues when documenting Reflex Sympathetic Dystrophy.

Failure to document absence of major nerve injury

Impact

Clinical: May lead to incorrect diagnosis of CRPS Type 2., Regulatory: Non-compliance with coding guidelines., Financial: Potential for denied claims due to incorrect coding.

Mitigation

Include EMG or nerve conduction study results in documentation.

Using unspecified codes when laterality is documented

Impact

Reimbursement: May lead to reduced reimbursement rates., Compliance: Non-compliance with coding specificity requirements., Data Quality: Decreases the accuracy of clinical data.

Mitigation

Ensure specific laterality is coded when available.

Specificity of coding

Impact

Risk of audits due to use of unspecified codes when specific codes are applicable.

Mitigation

Ensure documentation supports the use of specific codes.
