ICD 10 CM M88.829 | Description & Clinical Information

ICD 10 M88.829 describes a chronic metabolic bone disease that affects the upper arm, known as osteitis deformans or Paget’s disease of the bone, which is characterized by bone enlargement and deformity, leading to weakness and easy fracturing of the affected bone, and its causes are unknown but may be inherited or caused by a virus, with the caveat that the provider does not document the right or left upper arm.

Official Description Of M88.829

The ICD 10 CM book defines ICD 10 code M88.829 as:

Osteitis deformans of unspecified upper arm
Parent Code Notes: M88

Excludes1: osteitis deformans in neoplastic disease (M90.6)

When To Use M88.829

The diagnosis describes by ICD 10 CM M88.829 pertains to Osteitis deformans in the upper arm region. This condition is marked by gradually increasing pain, enlarged bones, and damaged cartilage in the joints. It can manifest in various forms such as gait instability, bony deformity, fractures, bowing of weight-bearing bones and neurologic complications arising due to nerve compression.

To accurately diagnose this condition, a medical provider typically relies on a combination of the patient’s medical history and physical examination, various imaging techniques such as Xrays, computerized tomography or CT scans, magnetic resonance imaging or MRIs, or bone scans, and DXA scan to determine the bone mineral density. Laboratory examination of the blood tests for bone markers for bone resorption or production, as well as alkaline phosphatase. Additionally, a bone biopsy may be done to confirm the diagnosis.

Treatment options available for Osteitis deformans of the upper arm include reducing weightbearing, using an orthosis to support the bones, and medications such as bisphosphonates, calcitonin, alendronate, and other drugs that inhibit bone loss or prevent bone resorption, as well as analgesics to reduce pain. In cases of severe fractures or deformity, surgery may be required.

While the cause of Osteitis deformans is not entirely clear, medical professionals hypothesize that genetic factors play a significant role in the development of the condition. Other potential factors include viral infections, hormonal imbalances, and even lifestyle habits such as smoking and alcohol consumption.

Individuals who are at risk of developing Osteitis deformans in the upper arm include those who have a family history of the condition, those with certain genetic markers, and those who are over 40 years old. Additionally, certain medical conditions such as Paget’s disease and hyperparathyroidism may increase the risk of developing the condition.

It’s important for medical coders to understand the nuances of coding Osteitis deformans of the upper arm, including the appropriate use of modifiers and documentation requirements. Accurate coding and record-keeping can help ensure that patients receive the appropriate treatment and care. As such, medical coders are advised to stay up-to-date on the latest coding guidelines and best practices in order to ensure compliance with regulatory requirements and ethical standards.
