ICD-10 Code Z13.220
Screening for lipoid disorders
What is the code Z13.220?
ICD-10-CM code Z13.220 stands for "encounter for screening for lipoid disorders." This code is used when a patient undergoes screening specifically to detect lipid disorders, which can include conditions like hypercholesterolemia and hyperlipidemia.
Detailed description of Z13.220
ICD-10 code Z13.220 is utilized for encounters where the primary reason for the visit is to screen for lipoid disorders. These disorders involve abnormal levels of lipids in the blood, including cholesterol and triglycerides, which can lead to conditions such as atherosclerosis and cardiovascular diseases. Screening is often part of preventive healthcare to identify potential risk factors early.
Symptoms commonly associated with Z13.220
While Z13.220 is a screening code and not directly tied to symptoms, lipid disorders themselves can be asymptomatic or present with symptoms such as:
- High blood pressure
- Chest pain
- Xanthomas (fatty deposits under the skin)
- Arcus senilis (a gray or white arc visible above and below the outer part of the cornea)
Related and similar ICD-10 codes
- E78.0: Pure hypercholesterolemia
- E78.1: Pure hyperglyceridemia
- E78.2: Mixed hyperlipidemia
- E78.49: Other hyperlipidemia
- Z13.6: Encounter for screening for cardiovascular disorders
Appropriate usage of Z13.220 for billing
Z13.220 should be used when the primary purpose of the visit is for the screening of lipoid disorders. It is not appropriate for use in visits where the patient is already diagnosed with a lipid disorder; in such cases, the specific diagnosis code (e.g., E78.0 for hypercholesterolemia) should be used. Proper provider documentation in their assessment is important to support the use of this screening code.
Instructional guidelines for coding Z13.220
- Screening is the testing for disease or disease precursors in asymptomatic individuals so that early detection and treatment can be provided for those who test positive for the disease.
- Inclusion terms for Z13.220 are: encounter for screening for cholesterol level, encounter for screening for hypercholesterolemia, and encounter for screening for hyperlipidemia. These terms describe the type of screening for which this code is to be used.
- There is an excludes 1 note found at category Z13, encounter for screening for other diseases and disorders that is applicable to code Z13.220 indicating that an encounter that is for diagnostic examination rather than screening should be coded to the sign or symptom instead of Z13.220.
- Refer to the ICD-10-CM guidelines section I.C.21.c.5. regarding proper coding of encounters for screening examinations for general guidance that is applicable to coding Z13.220.
Common pitfalls in coding with Z13.220
- Using Z13.220 for patients with a known lipid disorder instead of the specific diagnosis code.
- Failing to document the necessity for the screening, which can lead to claim denials.
- Incorrectly using Z13.220 for follow-up visits related to lipid disorders rather than for initial screenings.

Conclusion
ICD-10-CM code Z13.220 is used for encounters that are specifically for screening an asymptomatic patient for lipoid disorders. Proper use of this code requires clear documentation and a focus on preventive care. Understanding the nuances of this code helps ensure accurate billing and coding, ultimately supporting effective patient care and practice management.
