The first steps for a lumbar DDD diagnosis include the following:

The above diagnostic methods are typically enough to diagnose pain from a spinal disc, and most cases can be diagnosed by visiting a primary care physician. Other cases may require insight from a spine specialist and/or additional testing. In order to locate the specific segment of disc degeneration, diagnostic imaging tests may be used.
Disk Xray is a disk usage statistics viewer, duplicate file and folder finder and cleanup tool for macOS. Disk Xray performs three fundamental functions - and it performs them well offering maximum security to restore all files in case you remove something accidentally. Disk Xray requires macOS 10.10 or later. Baal is a remote control and disk imaging system for computer forensics. Baal will use a Linux PXE boot, dd, and parted to replace and retrieve disk images and store them on a server. Common forensics scans and tests can then be performed on images. X-rays provide for excellent bony detail because bone consists mainly of calcium. However, discs and nerve roots do not have any calcium, so an x-ray does not capture an image of these structures. An x-ray, therefore, cannot be used to diagnose lumbar disc herniation or other causes of nerve pinching.

A definitive diagnosis for lumbar DDD may require an MRI scan to ensure that other issues are not contributing to pain, such as a fracture or disc herniation. If surgery is needed, an imaging test is required prior to the procedure to accurately locate the degenerated disc and plan the surgery.

An MRI (magnetic resonance imaging) scan uses a high-powered magnet to align and detect water molecules in the body, which allows doctors to visualize soft tissues such as muscles, ligaments and tendons, and spinal discs. MRI scans rely on magnetism rather than radiation—used in x-ray and CT scans—so there is little risk involved in an MRI scan, and scans are not painful.

MRI scans can provide useful information concerning:
See Do I Need an MRI Scan?
Studies have shown that MRI findings of mild or significant disc degeneration are found on scans of patients with severe pain and minimal or no pain. Additionally, many painful conditions may not show up on an MRI, such as a tear in the disc’s outer rings or some cases of herniated discs. For this reason, a diagnosis cannot rely solely on imaging tests and must be used in combination with a medical history and physical examination.
