About CPT 83704
CPT 83704 is a Current Procedural Terminology code in the Pathology/Lab category maintained by the American Medical Association. The CMS short descriptor reads "Lipoprotein bld quan part". For the full AMA long descriptor and clinical guidance, refer to the current CPT code manual.
Documentation specificity, correct ICD-10 linkage, and modifier accuracy determine whether 83704 pays cleanly or triggers a denial. Verify CMS National Physician Fee Schedule status, applicable Medicare LCDs, and any payer-specific medical policies before submission.
83704 has 10 NCCI bundling edit pairs documented. Run your scrubber against the NCCI quarterly update before submission. When clinically warranted, use modifier 59 or the X-modifiers (XE, XS, XP, XU) to bypass an indicator-1 edit, with chart documentation supporting the distinct service.
Code Properties
RVU Breakdown
Every CPT code’s Medicare payment is calculated from three Relative Value Unit components: physician work, practice expense, and malpractice. Together they multiply by the conversion factor to produce the payment amount.
Payment = Total RVU × Conversion Factor ($33.4009) × Geographic Adjustment (GPCI). National averages shown. Actual payment varies by locality.
NCCI Bundling Edits
10 pairsThese codes trigger National Correct Coding Initiative edits when billed with 83704. An indicator of 0 means the pair cannot be unbundled. Indicator 1 means modifier 59 or X-modifiers may allow separate billing with supporting documentation.
Billing 83704 alongside a bundled code without the correct modifier generates CARC 97 denials. Payers often flag these as audit risks. Document medical necessity for the separate service and apply modifier 59 or the appropriate X-modifier (XE, XS, XP, XU) only when clinically justified.

Bundling denials on 83704 are recoverable when the edit indicator is 1 and the chart documents a distinct, separately identifiable service. Our coders verify the indicator and pick the precise X-modifier (XE, XS, XP, XU) instead of defaulting to modifier 59.
Applicable Modifiers
Modifiers commonly paired with 83704 based on its category. Apply only when the clinical circumstance warrants. Incorrect modifier use is a top audit target.
Component split modifiers (26 professional, TC technical) are the most under-applied modifiers in diagnostic billing. Practices that bill global on services where they only provided the read silently invite refund requests. We split components correctly at submission.
Supporting ICD-10 Diagnoses
These diagnosis codes commonly support medical necessity for CPT 83704. Using the correct ICD-10 prevents CARC 50 denials. Payer rejects when the diagnosis doesn’t support the procedure.
CARC 50 medical-necessity denials carry both rework cost and an audit-risk signal when patterns repeat. Our coders verify ICD-10 specificity and policy alignment at the coding stage so these losses get prevented upstream.
