M61.279
Paralytic calcification and ossification of muscle, unspecified ankle and foot
Clinical Classification Guidelines
Medical Intelligence & Overview
Paralytic calcification and ossification of muscle refers to abnormal hardening processes where calcium deposits or bone formation occur within muscles affected by paralysis, specifically around the ankle and foot. This condition can lead to stiffness, reduced movement, and discomfort, impacting mobility and quality of life. It is a relatively rare complication often associated with nerve injuries, trauma, or neurological diseases that cause paralysis of the affected muscles.
Causes & Symptoms
Clinical Causes: Nerve injuries leading to paralysis of muscles around the ankle and foot Trauma or injury to the muscles or nerves in the lower extremities Neurological conditions such as stroke, multiple sclerosis, or spinal cord injuries Prolonged immobility or paralysis following surgery or illness Chronic inflammation or infection in muscle tissues Disorders involving abnormal calcium metabolism
Key Symptoms: Muscle stiffness and localized swelling Palpable hard lumps or masses within the affected muscles Reduced range of motion in the ankle and foot joints Pain or discomfort during movement or at rest Weakness or difficulty moving the ankle or foot Possible skin changes over the affected area, such as redness or warmth
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess muscle hardness, swelling, and range of motion X-rays to visualize calcium deposits or ossified tissue within muscles Ultrasound imaging for detailed assessment of soft tissue calcifications MRI scans to precisely locate and determine the extent of ossification Blood tests may be performed to rule out metabolic causes affecting calcium levels
Treatment Protocols: Physical therapy to maintain joint mobility and muscle function Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain Extracorporeal shock wave therapy aimed at breaking down calcium deposits Surgical intervention to remove calcified or ossified tissue in severe cases Addressing underlying causes like correcting metabolic imbalances or managing neurological conditions Use of orthotics or assistive devices to improve mobility
Clinical Advice & FAQs
Billing Guidance

Documentation
How do I report M61.279?
