Time Span Code Reimbursement Criteria

Time Span reimbursement criteria

Reimbursement is constrained by the time parameter in the code description, CPT parentheticals, or other AMA/CMS guidance. Specific rules and examples follow.

Time Span Codes reimbursed only once per defined time period for the same member by the Same Group Physician and/or Other Qualified Health Care Professional.

When selecting the billed procedure, choose the procedure name that accurately identifies the services performed per CPT coding guidance.

Determination of the time period is based on AMA/CMS sourcing including the CPT/HCPCS code description, CPT book parentheticals, and other AMA or CMS publications.

Calendar month rule: If a code specifies 'calendar month', 'per month' or 'monthly', reimbursement is allowed once per individually named calendar month (e.g., January). If a code description specifies 30 or 31 days, that many days must pass since the last submission before reimbursement is allowed again.

Modifier recognition: Modifiers (for example 59, 76) are not recognized to permit additional reimbursement within the designated time span; reimbursement is governed by the code's time-span parameter and CPT/CMS guidance.

Comprehensive vs component codes: When related Time Span Codes that share a common portion of the code description are both reported during the same time span for the same patient by the Same Group, reimburse only the code with the most comprehensive description; the related component code(s) are inclusive and not separately reimbursable. No modifier will override this denial.

Exceptions / special cases

CPT codes 93224-93227 reported with modifier 52 are excluded from the Time Span Codes Policy and are handled under the Reduced Services Policy.
End-Stage Renal Disease (ESRD) codes 90951-90962: reimburse the single most comprehensive outpatient ESRD code submitted for the applicable age category once per month.
Transitional Care Management codes 99495 and 99496: only one individual may report these services and only once per patient within 30 days of discharge; selection between 99495 and 99496 is based on medical decision making and timing of the first face-to-face visit per CPT parentheticals.

Operational note: UnitedHealthcare Medicare Advantage will reimburse the code only once during the defined time period for the same member by providers reporting under the same Federal Tax Identification number (Same Group).

Billing and Provider Action Notes

Billing Rule

Reimbursement frequency for Time Span Codes

UnitedHealthcare will reimburse a CPT or HCPCS Time Span Code (a code that specifies a reporting period, e.g., weekly or monthly) only once during the defined time period. The applicable time period is determined from CPT/HCPCS and AMA/CMS guidance (code description, CPT parentheticals, CPT book guidance, or CMS publications). When multiple providers or clinicians submit claims for the same member and same Time Span during the defined period, reimbursement is made only once for that Time Span and should be applied to the provider eligible under the Same Group Physician and/or Other Qualified Health Care Professional rule (same Federal Tax Identification number).

Applies to CPT and HCPCS Level II Time Span Codes (reported by calendar month or other CPT-specified period)
Reimburse once per defined time period for the same member
When multiple providers bill for the same Time Span, select the provider eligible per Same Group Physician and/or Other Qualified Health Care Professional (same group/TIN)
