ICD 10 CM M87.122 | Description & Clinical Information

ICD 10 M87.122 describes a medical condition known as osteonecrosis, which is characterized by the death of bone tissue in the left humerus or upper arm bone due to the narrowing of blood vessels caused by certain drugs that interfere with lipid breakdown, leading to the accumulation of lipids in the blood vessels and ultimately disrupting the blood supply to the affected bone, resulting in bone death.

Official Description Of M87.122

The ICD 10 CM book defines ICD 10 code M87.122 as:

Osteonecrosis due to drugs, left humerus
Parent Code Notes: M87.1

Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Parent Code Notes: M87

Includes: avascular necrosis of bone

Excludes1: juvenile osteonecrosis (M91-M92)
osteochondropathies (M90-M93)

Use additional code to identify major osseous defect, if applicable (M89.7-)

When To Use M87.122

The diagnosis describes by the ICD 10 CM M87.122 code pertains to osteonecrosis or a degenerative condition that occurs as a result of drug use. This condition affects the left humerus bone and can cause gradually increasing pain, limited range of motion, limping when it affects the lower extremities, and numbness when it involves nerve damage.

To diagnose this condition, providers consider various factors like the patient’s medical history, symptoms, and physical examination. Additionally, providers use imaging techniques to determine the extent of the damage. Such imaging techniques include computerized tomography or CT scans, magnetic resonance imaging or MRI, bone scans and DXA scan, which checks the bone mineral density. To further confirm the diagnosis, laboratory examinations of the blood are done to check for erythrocyte sedimentation rate or ESR. Arthroscopy or bone biopsy may be necessary to complete the diagnosis and determine the extent of damage.

Once diagnosed, there are several treatment options available for patients. Reducing weight-bearing activities to give the bone time to heal is crucial. Range of motion exercises helps maintain flexibility and prevent muscle stiffness. Electromagnetic stimulation is an option for encouraging new bone growth while epidural or nerve blocks are used to reduce pain. Medications such as analgesics and nonsteroidal anti-inflammatory drugs called NSAIDs have been proved to relieve pain and inflammation. In severe cases, surgical intervention may be required.

Patients must work closely with their healthcare providers to get the right diagnosis and proceed with appropriate treatment. As with most medical conditions, early detection and proper treatment are crucial to restoring good health. Therefore, it is essential to take measures to prevent osteonecrosis due to drug use by abstaining from drug abuse or following the right dosage regiment as prescribed by a qualified medical practitioner.
