Detailed (?) extremity exam with 1995 guidelines

Best answers
There isn't a lot of information out there about this, at least that I can find.

Here is my exam, and I'm trying to figure out if this justifies a "detailed" extremity exam.

VS: (documented but not reiterated here).
GENERAL: (documented but not reiterated here).
RESP: (documented but not reiterated here).
CVS: (documented but not reiterated here).
EXTREMITIES (LUE): Hand normal to inspection and nontender. Wrist normal to inspection and nontender. Forearm with bony and soft tissue tenderness, ecchymosis and swelling. Several areas of early ecchymosis, red/purple. Able to move elbow with FROM. Elbow with bony and soft tissue tenderness. Arm normal to inspection and nontender. Shoulder normal to inspection and nontender. Neuro: Sensation normal. Vascular: No vascular compromise. Skin: Warm, dry, intact.

(Side note: Some in our office count the above SKIN, VASCULAR, and NEUROLOGIC as their own Organ Systems rather than part of the EXTREMITIES exam which is where I count it in this example, due to the fact that it is not a full body SKIN, VASCULAR, or NEUROLOGIC exam and simply pertaining to that particular extremity.)

In addition, I've had an auditor tell me that if only one extremity is reviewed and documented, as opposed to all extremities, it should count as a MSK organ system rather than EXT body system. This is NOT how I understood it. She also has stated that she has never seen a "detailed extremity exam" with 1995 guidelines.

The above exam, under 1995 guidelines, I'm thinking is a Detailed exam due to being 2-7 with one in detail.

Am I understanding this correctly?

Any direction is greatly appreciated.
