Billing and Submission Rules for Providers

Billing Rule

Report add-on codes only with required primary service and same provider/FTIN

Add-on codes must be reported in addition to an appropriate primary service by the Same Individual Physician or Other Qualified Health Care Professional reporting the same Federal Tax Identification Number on the same date of service unless otherwise specified. Add-on codes reported as stand-alone codes are not reimbursable. Although add-on codes may be submitted on a separate claim from the primary, UnitedHealthcare recommends submitting the add-on and primary procedure codes on the same claim form.

Add-on codes are reimbursable only when submitted with an appropriate primary procedure/service by the Same Individual Physician or Other Qualified Health Care Professional (same Federal Tax ID).
Add-on codes reported as stand-alone codes will not be reimbursed per CPT and CMS guidance.
UnitedHealthcare recommends reporting add-on and primary procedure codes on the same claim form, though separate claim submission is permitted unless otherwise specified.

Key Definitions

Add-on code — definition and reimbursement conditions

DefinitionAdd-on codes describe additional intra-service work associated with a primary service/procedure and are reported in addition to the appropriate primary procedure.

Reimbursement condition - primary requiredAdd-on codes are reimbursable only when submitted with an appropriate primary service/procedure; add-on codes reported as stand-alone codes are not reimbursable.

Claim submissionAdd-on codes may be submitted on a separate claim from the primary, but UnitedHealthcare recommends reporting the add-on and primary on the same claim form.

Same Individual Physician or Other Qualified Health Care Professional — definition

DefinitionThe Same Individual Physician or Other Qualified Health Care Professional is the same individual rendering health care services who reports the same Federal Tax Identification number.

Billing implicationThe Same Individual Physician must report both the add-on and the primary procedure unless policy specifies otherwise for group/specialty exceptions.

PurposeEnsures the add-on is billed by the individual who provided the related primary service for reimbursement consistency.

Stand-alone code — definition

DefinitionStand‑alone code: a code reported without another primary service/procedure code by the Same Individual Physician or Other Qualified Health Care Professional.

Reimbursement consequenceCodes designated as add-on that are submitted as stand‑alone codes will not be reimbursed in accordance with CPT and CMS guidance.

Relation to add-on rulesA stand‑alone report of an add-on code does not satisfy the policy requirement that an appropriate primary procedure be present for reimbursement.

Definitive and Interpretive Sources — definitions and examples

Definitive Source — definitionDefinitive Sources contain the exact codes, modifiers or very specific instructions from the given source (i.e., sources that specify exact code/modifier instructions).

Interpretive Source — definitionInterpretive Sources include guidelines without exact code or modifier information and require interpretation to map codes to guidance; interpretations may be applied to surrounding or similar codes based on related definitive edits.

Examples / useUnitedHealthcare uses definitive sources where available to map add‑on to primary codes; when absent, interpretive sources (CPT, CMS, specialty society guidance) inform determinations.
