ICD-10-CM Code I25.83

Valid for Submission

I25.83 is a billable code used to specify a medical diagnosis of coronary atherosclerosis due to lipid rich plaque. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code I25.83 might also be used to specify conditions or terms like coronary atherosclerosis or lipid-rich atherosclerosis of coronary artery.

The code I25.83 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.

The code is commonly used in cardiology medical specialties to specify clinical concepts such as selected atherosclerosis, ischemia, and infarction.

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

• Adult diagnoses - Adult. Age range is 15–124 years inclusive (e.g., senile delirium, mature cataract).
• Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual’s health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
