Claims submission responsibility

You are responsible for submitting accurate CMS-1500 claims using the CPT/HCPCS codes and modifiers that correctly describe the services provided. UnitedHealthcare may use reasonable discretion in interpreting and applying this policy and may consider coding methodology, industry-standard reimbursement logic, regulatory requirements, benefits design and other factors when determining reimbursement.

• Submit accurate CMS-1500 claims using correct CPT/HCPCS codes and modifiers.
• UnitedHealthcare may apply discretion in interpreting and applying this policy.

Mobile unit POS reporting

When a mobile unit furnishes services to an entity that has an existing Place of Service (POS) code, report the POS for that entity (for example, POS 21 for an inpatient hospital). If the mobile unit is not serving an entity described by an existing POS code, report POS 15 (mobile unit). When intraoperative neuromonitoring (IONM) services (e.g., 95940 and G0453) and associated study codes are reported in a facility POS, the Technical Component will be denied. Services with a Technical Component performed in a facility are included in the facility’s global payment and are not separately reimbursable to physicians/QHPs.

• If mobile unit serves an entity with an existing POS, use that entity's POS (e.g., 21).
• If mobile unit does not serve an entity with an existing POS, report POS 15.
• IONM services (95940, G0453) and associated study codes reported in a facility POS: Technical Component will be denied.
• Services with a Technical Component performed in a facility are included in the facility global payment and are not separately reimbursable to physicians/QHPs.

Documentation requirement for radiology interpretations

When billing radiology interpretation (modifier 26) on the same day as an E/M service, submission of a distinctly identifiable, signed written radiology interpretation report is required before UnitedHealthcare will consider separate reimbursement for the radiology interpretation. Modifier 25 on the E/M does not waive the requirement — it identifies a separate E/M, but the radiology interpretation itself still requires the signed report.

• Distinctly identifiable signed written radiology interpretation report required when billing modifier 26 with an E/M on same day.
• Modifier 25 on the E/M does not bypass the radiology interpretation documentation requirement.

Modifier guidance for repeat procedures and labs

Use modifiers 76 or 77 to identify repeat procedures performed at different episodes on the same day. Do not use modifiers 76 or 77 to indicate repeat laboratory services. For repeat or distinct laboratory services, use modifier 59 or the CMS/AMA X{E, P, S, U} modifiers or modifier 91 as appropriate (59, XE, XP, XS, XU, or 91). Separate consideration for reimbursement will not be given to laboratory codes reported with modifier 76 or 77.

• Modifiers 76 or 77: indicate subsequent procedures at different episodes the same day.
• Do not use 76/77 for repeat laboratory services.
• Use 59, XE, XP, XS, XU, or 91 to indicate repeat/distinct laboratory services per AMA/CMS guidance.

Duplicate edit behavior for PC/TC/global code series

For code series that explicitly represent Professional Component (PC), Technical Component (TC), and global services (for example 93000/93005/93010), duplicate-edit logic applies. If the global code is received first, subsequent component code(s) will be denied; if a component code is received first, the global code will be denied. Do not use modifiers 26 or TC to report services when the intent is inherent in the code description for that PC/TC/global series.

• Duplicate editing applies to explicit PC/TC/global code series (e.g., 93000/93005/93010).
• If global test received first, component codes will be denied.
• If a component code is received first, the global test will be denied.
• Do not append modifier 26 or TC to codes where the PC/TC intent is inherent in the code description.
