ICD-10 code M94.0 is a billable medical diagnosis code used for healthcare documentation and insurance reimbursement to identify Chondrocostal Junction Syndrome, commonly known as Tietze syndrome. This condition is characterized by inflammation of the costal cartilage, most often at the upper ribs where they attach to the sternum, resulting in localized chest pain, tenderness, and sometimes visible swelling.
It is clinically important because the symptoms can closely resemble cardiac-related chest pain, making proper diagnosis essential to rule out more serious conditions such as myocardial infarction or other cardiopulmonary disorders.
Accurate documentation and Medical Coding Services also play an important role in ensuring proper diagnosis reporting, treatment tracking, and healthcare reimbursement.
Billable Status: Yes
ICD-9 Code Equivalent: 733.6
Clinical Overview
Chondrocostal junction syndrome is typically a benign, self-limiting musculoskeletal condition. It most commonly affects the second or third costochondral junction and may be triggered by:
- Repetitive chest wall strain
- Upper respiratory infections with excessive coughing
- Physical trauma or injury to the chest
- Heavy lifting or strenuous upper body activity
Patients usually present with:
- Localized chest wall pain
- Tenderness on palpation of affected ribs
- Pain that may worsen with movement, deep breathing, or coughing

Diagnosis & Evaluation
Diagnosis is primarily clinical, based on patient history and physical examination. However, healthcare providers may order tests such as:
- ECG (to rule out cardiac causes)
- Chest X-ray (to exclude fractures or lung pathology)
- Blood tests if infection or inflammation is suspected
Treatment Approach
Management is generally conservative and may include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Rest and activity modification
- Local heat or cold therapy
- In some cases, physical therapy or corticosteroid injections
Related / Synonyms
- Tietze syndrome
- Costochondritis
- Costal cartilage inflammation
- Slipped rib syndrome (related but distinct condition)

Clinical Importance for Billing
Correct use of ICD-10 code M94.0 ensures:
- Accurate documentation of musculoskeletal chest pain
- Proper insurance reimbursement
- Clear differentiation from cardiac or pulmonary emergencies
- Improved continuity of care across providers
ICD-10 code M94.0 — Chondrocostal Junction Syndrome [Tietze] represents a well-defined, benign musculoskeletal condition that is far more specific than generic “chest wall pain.” The code is HIPAA-valid, billable without additional specificity, and covers a condition with a clear clinical fingerprint: localized swelling at an upper costal cartilage, reproducible on palpation, typically at the 2nd or 3rd rib, almost always unilateral.
FAQs:
What is the ICD-10 code for Tietze syndrome?
ICD-10-CM Code M94.0 is used for Tietze syndrome (Chondrocostal Junction Syndrome). It falls under Other Disorders of Cartilage (M94) and is a billable, HIPAA-compliant code that requires no additional specificity.
How is Tietze syndrome different from costochondritis?
Tietze syndrome causes chest pain with swelling at the affected rib cartilage, while costochondritis causes chest pain without swelling. Tietze usually affects a single rib junction, is more common in younger people, and has a separate ICD-10 code.
How long does Tietze syndrome last?
Most cases of Tietze syndrome improve within weeks to months with proper treatment. Some people may experience recurring symptoms, especially with repetitive physical strain, but full recovery without lasting damage is typical.
