Spinal Stenosis

If a patient has degenerative AND congential spinal stenosis, what are the correct dxs? I have an old coder's desk reference that says degenerative is coded to category 722 and congential is coded to categories 723-74, but someone else said to use 756.19 for the congential. Does it require one or two dxs?
Thank you.

re: Spinal Stenosis

The most common spinal congenital deformities include lordosis (code 754.2), kyphosis (code 756.19), and scoliosis (code 754.2). Spinal stenosis (codes 723.0 or 724.0x depending on whether it occurs in the cervical region) is a narrowing of the nerve cavities, spinal canal, and the intervertebral foramen. Patient may have congenitally narrow spinal canal. To correctly code spinal stenosis, coders need to know where in the spine it occurs. Because a variety of codes exist, coders must refer to the physician documentation for the specific details. Codes from Chapter 14 may be used throughout the life of the patient. If a congenital anomaly has been corrected, a personal history code should be used to identify the history of the anomaly. Although present at birth, a congenital anomaly may not be identified until later in life. Whenever the condition is diagnosed by the physician, it is appropriate to assign a code from codes 740-759. The congenital condition can be a first listed or secondary code. Code first the condition you are treating and follow with congenital code (based on documentation).
