Procedure codes and diagnosis codes change every year, challenging coders and clinicians alike. This October is no different.
There are 360 new diagnosis codes, 142 codes were deleted and there were 226 revisions to the ICD-10-CM database, bringing us to a total of 71,714 diagnosis codes.
There are always some wording changes that don’t change the meaning of the code. This year, some code descriptions went from “extremities” to “extremity” or “veins” to “vein.” A spelling error or two was corrected.
ICD-10 changes – Exclude1 notes become Excludes2 notes
One of the substantive changes was that some Exclude1 notes became Excludes2 notes.
Take a look at the general guidelines at the front of your ICD-10 book for an example of an exception to the Excludes1 rule. (Using an electronic copy instead of a book? You can download the general guidelines from the CDC website.)
New diagnosis codes
There are new codes for:
- mast cell neoplasms C96
- pulmonary heart disease I27
- congestive heart failure I50
- substance abuse (see below)
In the behavioral health chapter, we had codes for substance dependence in remission. This year, there are codes for substance abuse in remission. Of course these are specific by the substance, alcohol, marijuana, etc. (F10—F19)
More new diagnosis codes include right, left, and lateratlity
Ophthalmology, which already had many codes defined as right, left, or bilateral, got more.
Did you ever wonder why N63, unspecified lump in breast didn’t have laterality? Well, it does in 2018. In addition to laterality there are specific codes for the location of the lump, (upper inner quadrant, axillary tail, etc.)
