List of ICD10 Diagnoses we don't code

See also: List of CCI procedures we don't code. For a general rationale of how we decide what to include, see Reasoning around moving to ICD10 and our subset of it.

Dxs that we have considered and decided not to code

• Muscle Spasm
• Mild cognitive impairment/decline
  • There are options here, one could decide to use, as appropriate: Encephalopathy, NOS or Encephalopathy, septic or metabolic or Brain disorder, NOS. However, this is such a vague and variable term, that it's rarely appropriate to code it in the absence of a specific disorder/disease.
• Intravenous drug abuse (IVDA) - there is no ICD10 code for this and we don't have a specific need to add a special code
• Past amputation - see Amputation

lump dxs

We have some lump dxs (e.g. Mass, lump or swelling, skin or subcutaneous tissue, NOS, Breast, unspecified lump (nodule, mass), Mass, lump or swelling, intra-abdominal or pelvic). These are intended for tactile findings.

For lumps or masses that are detected in imaging rather than tactile, use Lung, diagnostic imaging, abnormal or appropriate other abnormal imaging code.

"work-up for cancer" / i.e. old *06 subcodes for all tumors

If the cancer has not been confirmed then it should not be coded as cancer. Code relevant test abnormal test results or symptoms.

ExpandExample:

"I have a patient who comes in with vague respiratory and gi symptoms. They did a chest xray and found a lung mass. They are now working him up for a probable lung ca, with mets to various places. In the old coding I would use ca-nyd. I actually use the ca nyd subcode a lot. I’ve talked to you about this before, because there is no ca nyd in icd10. You told me that you either have cancer or you don’t. For this particular patient I really wouldn’t have anything else I could code in icd10 for him. His symptoms are extremely vague. I don’t really like coding just symptoms, if there isn’t a proper admit diagnosis that fits better anyway. I found a “neoplasm of uncertain behavior (i.e. uncertain if benign or malignant), nos”, but I don’t really like that one. It doesn’t really fit. Is it possible to get something like “admit for workup of malignancy”, or something along those lines?" (Debbie, 12:40, 2018 October 4 (CDT)) How should this be coded?

Other dxs collectors think should be included

If we don't have a dx code and you think we should have it, put a discussion here (use the pink button in the button bar). We will review it and either add it, or explain which code it should be coded under and make sure a future search would find it, or add an explanation above that we decided not to code it and why.

_q could we add the code 'aortic ulcer' as I have found that we have admitted numerous aortic dissections with this as the cause AG REPLY -- in ICD10 this is simply a subset of aortic dissection and is not coded separately. If in the extremely unusual situation where an aortic erosion or ulcer is present without a dissection, code it under Disorder of artery/arteries, NOS
