2025 ICD-10-CM code M88.821

Osteitis deformans (Paget's disease) affecting the right upper arm.

Follow official ICD-10-CM coding guidelines.If the cause of the osteitis deformans is known, an additional external cause code should be used.

Medical necessity for the diagnosis and treatment of M88.821 is established through clinical presentation of symptoms consistent with Paget's disease, confirmed by appropriate diagnostic imaging and laboratory findings.Treatment should be based on the severity of symptoms and potential for complications (such as fractures).

Diagnosis and management of osteitis deformans of the right upper arm involves obtaining a detailed patient history and performing a thorough physical examination. Imaging studies such as X-rays, CT scans, MRI, bone scans, and DXA are used to assess bone structure and density.Blood tests help measure markers of bone turnover. Treatment might include pain management, medication to slow bone loss (bisphosphonates), and surgical intervention if fractures occur.In some cases, referral to specialists may be necessary.

IMPORTANT M88.822 (Osteitis deformans of left upper arm), M88.829 (Osteitis deformans of unspecified upper arm)

In simple words: This code describes Paget's disease, a bone disease affecting the right upper arm.It causes bone to become enlarged and deformed, making them weaker and more prone to breaking.Symptoms can include pain, enlarged bones, and problems with joints. Doctors diagnose this using imaging tests (like X-rays), blood tests, and sometimes a bone sample.

M88.821, Osteitis deformans of the right upper arm, is a chronic metabolic bone disease characterized by bone enlargement and deformity, leading to bone weakness and increased fracture risk.The etiology is largely unknown, although a genetic predisposition or viral infection may play a role.Clinical presentation often includes gradually increasing pain, enlarged bones, and damaged joint cartilage. This can result in gait instability, bony deformities, fractures, bowing of weight-bearing bones, and neurological complications due to nerve compression. Diagnostic workup may include patient history and physical examination, imaging (X-rays, CT scans, MRI, bone scans, DXA), blood tests (alkaline phosphatase, bone markers), and potentially a bone biopsy.

Example 1: A 65-year-old male presents with increasing pain and swelling in his right upper arm. X-rays reveal characteristic bone changes consistent with Paget's disease.The diagnosis of M88.821 is made., A 70-year-old female experiences a spontaneous fracture of her right humerus.Further investigation reveals osteitis deformans of the right upper arm (M88.821), which contributed to the fracture. The patient undergoes surgical repair and medical management of her Paget's disease., A 72-year-old male with known Paget's disease experiences worsening pain in his right upper arm.He is treated with bisphosphonates, and his pain is closely monitored.M88.821 is used to document the ongoing management of his condition.

Detailed patient history including symptoms (pain, swelling, deformity, fractures), physical examination findings, imaging reports (X-rays, CT, MRI, bone scan, DXA), laboratory results (alkaline phosphatase, bone markers), and biopsy reports (if performed).Treatment plans, response to therapy, and any complications should also be documented.
