2025 ICD-10-CM code M91.2
Coxa plana, a hip deformity due to previous juvenile osteochondrosis.
Medical necessity for interventions related to coxa plana is established by demonstrating the impact of the condition on the patient's mobility and quality of life. Documentation should clearly link the diagnosis and the chosen treatment plan (conservative or surgical) to the patient's functional limitations and pain.
Physicians, particularly orthopedists and pediatricians, are responsible for diagnosing and managing coxa plana. Diagnosis typically involves physical examination, medical history assessment, X-rays, and sometimes other imaging studies like MRI. Treatment plans vary depending on the severity and stage of the condition, ranging from conservative measures like rest, physical therapy, and bracing, to surgical interventions in more complex cases.

In simple words: Coxa plana, also called Legg-Calvé-Perthes disease, is a hip problem that mostly affects children.It happens when the top part of the thigh bone doesn't get enough blood, causing the bone to soften and sometimes change shape. This can make the hip hurt and make it hard to walk.Usually, the bone heals itself over time, but it's important to get treatment to help the hip heal properly.
Coxa plana is a hip disorder primarily affecting children and adolescents, characterized by avascular necrosis (death of bone tissue due to interrupted blood supply) of the femoral head (the ball-shaped part of the thigh bone that fits into the hip socket).This condition disrupts the ossification (bone formation) process, leading to temporary deformity and potential long-term complications like osteoarthritis.The femoral head may flatten and deform during the course of the disease, but typically regenerates over a period of several years. This condition is also known as Legg-Calvé-Perthes disease.
Example 1: A 6-year-old boy presents with a limp and intermittent hip pain, particularly after physical activity.X-rays reveal flattening of the femoral head, consistent with early-stage coxa plana., A 10-year-old girl with a history of coxa plana diagnosed two years prior returns for follow-up. Imaging shows signs of reossification and improved femoral head shape., A young adult experiences early-onset hip osteoarthritis, attributed to a history of untreated coxa plana in childhood.
Thorough documentation should include details of the patient's symptoms (pain, limping, limited range of motion), physical examination findings, imaging results (X-rays, MRI, bone scans), treatment plan, and patient progress. It's crucial to document the stage of the disease and any functional limitations the patient experiences.
** Coxa plana typically resolves over time, but the healing process can take several years.Early diagnosis and appropriate management are essential to minimize long-term complications, such as hip osteoarthritis and gait abnormalities.
