The ICD-10-PCS codes for bilateral flexion contractures of the knees at 40 degrees with posterior capsulotomy via incision are:
* M01.12: Flexion deformity of the knee joint, bilateral
* 22725: Open release of the posterior capsule of the knee joint, bilateral
The first code, M01.12, is a diagnosis code that identifies the specific condition of bilateral flexion contractures of the knee joint. The second code, 22725, is a procedure code that describes the surgical procedure performed to correct the contractures.
