Short answer · Medically reviewed summary · Last updated: 2026-05-08
Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) does not have a unique, dedicated code in the ICD-10 or ICD-9 systems. Clinicians typically use the code G57.8 (Other specified mononeuropathies of lower limb) or M79.2 (Neuralgia and neuritis, unspecified) to document the condition for medical billing and insurance purposes. Why is there no specific ICD code for ACNES? Because Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is often underdiagnosed or misclassified as general abdominal pain, it lacks a specific entry in the International Classification of Diseases.

ICD10 code of Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) and ICD9 code
ICD-10 and ICD-9 codes for Anterior Cutaneous Nerve Entrapment Syndrome (ACNES), with classification details for clinicians, coders and patients.
Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) does not have a unique, dedicated code in the ICD-10 or ICD-9 systems. Clinicians typically use the code G57.8 (Other specified mononeuropathies of lower limb) or M79.2 (Neuralgia and neuritis, unspecified) to document the condition for medical billing and insurance purposes.
Why is there no specific ICD code for ACNES?
Because Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is often underdiagnosed or misclassified as general abdominal pain, it lacks a specific entry in the International Classification of Diseases. Medical coding for Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) remains reliant on broader neurological or musculoskeletal categories, which can sometimes complicate insurance authorization for specialized treatments like nerve blocks or neurectomy.
How is Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) diagnosed?
Diagnosis is primarily clinical, often utilizing the Carnett’s sign test, where pain increases when the patient tenses their abdominal wall muscles. Patients frequently undergo imaging (like ultrasound) to rule out other pathology, though Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) itself is often invisible on standard scans. At DiseaseMaps.org, 36 members have shared their journeys with this condition, highlighting the difficulty of obtaining a formal diagnosis when specific coding is absent.
What are the common clinical features?
The presentation of Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is highly specific. Key diagnostic indicators include:
- Sharp, localized abdominal pain, often unilateral.
- Positive Carnett’s sign during physical examination.
- Pain that does not fluctuate with bowel movements or menstrual cycles.
- Significant relief following a diagnostic trigger point injection (lidocaine block).
Next steps
- Consult a specialized surgeon or pain management physician familiar with Anterior Cutaneous Nerve Entrapment Syndrome (ACNES).
- Keep a detailed pain diary to share with your provider to help differentiate ACNES from gastrointestinal conditions.
- Connect with the 36 members on DiseaseMaps.org to discuss management strategies and provider recommendations.
