Critical illness myopathy
ICD-10 G72.81 is a billable code used to indicate a diagnosis of critical illness myopathy.
Critical illness myopathy (CIM) is a neuromuscular disorder characterized by muscle weakness and atrophy that occurs in patients who are critically ill, often in an intensive care unit (ICU) setting. It is typically associated with prolonged mechanical ventilation, sepsis, and systemic inflammatory response syndrome (SIRS). CIM is distinct from critical illness polyneuropathy (CIP), although both conditions can occur concurrently. The pathophysiology of CIM involves a combination of factors including muscle disuse, metabolic derangements, and inflammatory processes that lead to muscle fiber damage and dysfunction. Clinically, patients may present with generalized weakness, difficulty in moving limbs, and reduced muscle strength, which can significantly impact recovery and rehabilitation. Diagnosis is primarily clinical, supported by electromyography (EMG) findings and muscle biopsy when necessary. Management focuses on supportive care, addressing underlying causes, and rehabilitation to restore muscle function. Understanding CIM is crucial for healthcare providers, as early recognition and intervention can improve outcomes for critically ill patients.
Detailed notes on patient history, critical illness course, and muscle strength assessments.
Patients on prolonged mechanical ventilation with muscle weakness.
Ensure documentation reflects the acute nature of the condition and any interventions undertaken.
Neurological assessments, EMG results, and muscle biopsy findings.
Patients presenting with unexplained muscle weakness in the ICU.
Document differential diagnoses to support the use of G72.81.
Used to assess muscle function in patients suspected of having CIM.
Document the reason for EMG and findings.
Neurology specialists should ensure EMG results are clearly linked to the diagnosis.
