Manifestation codes are the codes that tell about the symptoms of an illness. Manifestation gives the advanced warning of a disease but it doesn’t describe the disease itself. So, we cannot consider it as a principal diagnosis. In this article, we’ll read about CM manual instructions but before that let’s understand what actually the manifestation codes signify.
Manifestation Codes Definition
A manifestation code is a characteristic sign of the primary illness. It describes the cause of the disease and reports another condition that is caused by the disease that is known as manifestation.
Many people confuse manifestation with etiology. Etiology tells what the patient has wrong with them while Manifestation tells how the etiology is present.
For example – A cataract is an eye disease that is a manifestation. People may develop this anomaly due to various reasons or etiology. Cataracts can occur due to diabetes or Glaucoma. So, here Diabetes or Glaucoma is etiology while the cataract is manifestation.
So, there is always a code for all the diseases. e.g. Diabetes code is 250
If Diabetes is the reason then the diabetes code first (250.5x). now, sequence the manifestation code i.e., the diabetic cataract code (366.41).
If Glaucoma is the reason then the glaucoma code first (365.0-365.9). now, sequence the manifestation code i.e., the glaucoma cataract code (366.31 ).
What are ICD 10 codes for manifestation?
ICD-10 is a code that translates a patient’s health condition from words into an alphanumeric code which permits easy storage retrieval and standardization for analysis. This ICD-10 is a 7 character long code. There are some guidelines available to code the underlying disease and the manifestation that occurs due to that disease.
Manifestation Codes in ICD 10
ICD-10 CM describes the two diagnoses associated with complications. The ICD 10 codes are the secondary diagnosis or in other terms, it is used to classify a diagnosis associated with manifestation. Before heading to ICD-10 instructions, read a few important things given below
- Alphabetic index – Parentheses are used in ICD 10 CM to identify manifestation codes.
- Tabular List – brackets are used to enclose explanatory wording or synonyms.
ICD-10-CM Manual Instructions
Manual instructions are there to help you choose and assign the correct diagnosis code. And this makes the claims process smooth and efficient. So, we’ve arranged the manual instructions in one place for you. Check below-
- Manifestation code can never be the only diagnosis. Keep this in mind.
- A Manifestation code is not the principal diagnosis so you cannot report it as first-listed.
- At first, You need to code the underlying disease.
- In the ICD-10 CM manual, blue highlights represent the manifestation codes.
- You will get a “Code First Underlying Disease” with the underlying disease code identified.
- Manifestation codes are the secondary codes in the alphabetic index.
- If there are both multiple body system manifestations and an underlying etiology –
- “use additional code” is for etiology
- “code first” if for manifestation
- “in disease classified elsewhere” may appear in the manifestation title.
- The code title is the manifestation code.
- “in disease classified elsewhere”, codes are not first list or principal diagnosis. Use them in conjunction with an underlying condition code and then the underlying condition.
To submit the claims follow the above guidelines which will help you reduce the chances of the claims being denied.
