Summary & Overview

CPT 1125F: Cancer Pain Severity Assessment During Chemotherapy or Radiotherapy

CPT code 1125F represents a documented measurement of pain severity for patients with cancer who receive chemotherapy or radiotherapy during the measurement period. The code is relevant to quality reporting and clinical documentation because it captures symptomatic burden among patients undergoing active cancer-directed therapy and supports monitoring of pain management needs at a national scale.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how 1125F is used in clinical workflows in oncology and ambulatory infusion settings, and how payers typically incorporate pain assessment data into quality programs and performance measures.

Readers will learn: the clinical context for reporting 1125F, typical sites of service and service type, common billing considerations, and where documentation aligns with quality measurement. The report also summarizes available benchmarking elements and policy-relevant points for national stakeholders. Data not available in the input are noted where applicable.

Billing Code Overview

CPT code 1125F documents a pain severity assessment for a patient with cancer who receives chemotherapy or radiotherapy during the measurement period. The code is reported when the patient experiences pain and the provider measures its severity.

Service type: Symptom assessment / pain management evaluation

Typical site of service: Oncology clinic, outpatient chemotherapy or radiation treatment setting, or other ambulatory care locations where cancer-directed therapy is administered.

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with metastatic breast cancer is receiving outpatient chemotherapy in an oncology infusion center. During a routine treatment visit, the oncology nurse or treating clinician performs a standardized pain assessment documenting presence and severity of cancer-related pain while the patient receives chemotherapy or radiotherapy. The assessment occurs during the measurement period (during an active course of chemo- or radiotherapy) and is recorded in the medical record. The documented finding that the patient experiences pain is reported with 1125F. Typical workflow steps include intake assessment, pain severity measurement (numeric rating scale or validated tool), documentation in the electronic medical record, clinician review, and inclusion of the code on the encounter or quality reporting documentation. Typical site of service is an outpatient oncology clinic or infusion center. Service type is a patient-reported/clinician-assessed symptom severity measurement specific to cancer treatment visits.
