Lipid panels are billed millions of times a year, and the coding looks simple until a Medicare claim denies for the wrong screening code or a repeat test inside the frequency window. This guide covers CPT 80061, the ICD-10 codes that support it for screening and for diagnosis, and Medicare's rules for each.
Quick answer: For lipid screening, use Z13.220 with commercial plans and Z13.6 for Medicare's cardiovascular screening benefit, which covers the panel once every five years. For patients with known lipid disorders, use the E78 code that matches the diagnosis, such as E78.5 (hyperlipidemia, unspecified) or E78.2 (mixed hyperlipidemia), and add Z79.899 when monitoring drug therapy.
Key takeaways
- CPT 80061: Total cholesterol, HDL and triglycerides on one specimen.
- Two screening codes: Z13.220 for most commercial plans, Z13.6 for Medicare.
- Five-year rule: Medicare covers screening lipids once every five years.
- Diagnostic is different: Patients with known lipid disorders or on lipid therapy are tested under diagnostic rules.
What Is CPT 80061?
CPT 80061 reports a lipid panel that includes total serum cholesterol (82465), HDL cholesterol (83718) and triglycerides (84478). All three must be performed to bill the panel, and the component codes should not be billed alongside it. LDL is usually calculated from these results; a directly measured LDL is reported separately with 83721 only when it is actually performed and supported.
Which ICD-10 Codes Support a Lipid Panel?
Screening codes
| ICD-10-CM | Description | Payer |
|---|---|---|
| Z13.220 | Encounter for screening for lipoid disorders | Most commercial plans |
| Z13.6 | Encounter for screening for cardiovascular disorders | Medicare cardiovascular screening |
| Z00.00 / Z00.01 | General adult medical exam | Routine physical; add the Z13 code |
Diagnostic and monitoring codes
| ICD-10-CM | Description |
|---|---|
| E78.5 | Hyperlipidemia, unspecified |
| E78.2 | Mixed hyperlipidemia |
| E78.00 | Pure hypercholesterolemia, unspecified |
| E11.9 | Type 2 diabetes without complications |
| Z79.899 | Other long term (current) drug therapy, such as statins |
Code the most specific E78 diagnosis the note supports, and check it against the current CDC ICD-10-CM files. For diabetes coding detail, see our diabetes ICD-10 codes guide.
What Are Medicare's Rules for Lipid Testing?
| Situation | Medicare rule |
|---|---|
| Screening, no known lipid disorder | Cardiovascular screening benefit: 80061 or components with Z13.6, once every 5 years, no cost sharing |
| Known lipid disorder or on lipid therapy | Diagnostic testing under the national lipid testing policy, at frequencies supported by the condition and treatment changes |
| Routine annual lipids with no qualifying reason | Not covered; ABN required to bill the patient |
CMS lists the screening details on its CMS cardiovascular disease screening page. Our ICD-10 codes for lab screening guide explains how screening and diagnostic codes interact.
The most common Medicare lipid denial is a screening panel coded Z13.220. Medicare's screening benefit is billed with Z13.6. Set a payer rule in your billing system so Medicare claims never go out with Z13.220 alone.
How to Bill a Lipid Panel Correctly
- Confirm all three tests were run. Otherwise bill the individual components.
- Decide screening or diagnostic. A known lipid disorder or lipid therapy makes it diagnostic.
- Use the payer's screening code. Z13.6 for Medicare, Z13.220 for most commercial plans.
- Check the last screening date. Medicare screening repeats inside five years will deny.
- Do not add components. 82465, 83718 and 84478 are included in 80061.
Common Lipid Panel Denials
| Denial cause | Fix |
|---|---|
| Medicare screening coded Z13.220 | Use Z13.6 |
| Screening repeated within five years | Check history; collect an ABN if no diagnostic reason |
| Components billed with 80061 | Bill the panel only |
| Unspecified E78.5 when the note is more specific | Code the documented type |
Small lab denials add up across a year. Our laboratory billing services and denial management teams catch them before they age out. For related lab coding, see the BMP ICD-10 code guide.
Conclusion
Lipid panel coding turns on one question: screening or diagnostic. Use Z13.220 for commercial screening and Z13.6 for Medicare, which covers screening once every five years. For patients with known lipid disorders or on therapy, use the specific E78 code and Z79.899, and never bill the components alongside 80061.

Lipid Panel ICD-10 FAQs
Z13.220 for most commercial plans and Z13.6 for Medicare's cardiovascular screening benefit.
Once every five years under the cardiovascular disease screening benefit.
CPT 80061, which includes total cholesterol, HDL cholesterol and triglycerides.
The lipid disorder being treated, such as E78.5 or E78.2, plus Z79.899 for long-term drug therapy.
No. HDL cholesterol is part of the panel, so billing 83718 with 80061 is unbundling.
No. A directly measured LDL is reported with 83721 when it is performed and medically necessary.
