Use Code
## **What is HCPCS code G0103?**
HCPCS code G0103 is used to report a screening prostate-specific antigen (PSA) test for the early detection of prostate cancer. This test measures the total concentration of PSA, a glycoprotein produced by prostate epithelial cells, in the patient’s blood. Elevated PSA levels may indicate prostate cancer, benign prostatic hyperplasia (BPH), or prostatitis.
The PSA screening test is performed as a preventive service for asymptomatic male patients. Medicare covers one screening PSA test every 12 months for beneficiaries who meet eligibility criteria. This test is often performed in conjunction with other prostate cancer screening methods, such as the digital rectal examination (DRE), although DRE is billed separately.
Clinical guidelines vary regarding PSA screening due to risks of overdiagnosis and overtreatment, but it remains a key diagnostic aid in identifying prostate cancer at an earlier, more treatable stage in appropriate populations. The test is most commonly offered to men age 50 and older, or earlier for those with higher risk factors such as African American ethnicity or a family history of prostate cancer.
## **Documentation requirements**
For a G0103 claim to be considered for payment, the medical record must support medical necessity and to prove that the test was performed for screening purposes. Key documentation requirements include:
- **Patient eligibility**: The patient must be a male older or equal to 50 years old and preferably a Medicare beneficiary.
- **Screening intent**: The documentation must clearly state that the purpose of the test was for screening for malignant neoplasm of the prostate. To add, one must add the date of the prior PSA screening to prove the 12-month interval compliance.
- **Absence of symptoms**: The patient must be asymptomatic. If the patient has any signs or symptoms related to a prostate issue (e.g., frequent urination, pain, blood in urine), the test is considered diagnostic, and a different code should be used.
- **Diagnosis code**: The appropriate diagnosis code for screening is Z12.5 (Encounter for screening for malignant neoplasm of prostate). This is a crucial detail for distinguishing the claim from a diagnostic test.
## **Billing requirements**
To avoid denial of claims, the following billing requirements must be kept in mind when billing for HCPCS code G0103:
- **Frequency**: G0103 is typically covered once every 12 months. Medicare's frequency calculation begins the month after the previous test was performed, so a patient is eligible for a new screening test 11 months after the month of their last one.
- **Patient demographics**: For Medicare, the patient must be a male beneficiary who has attained age 50.
- **Payment**: For Medicare, the deductible and coinsurance are often waived for this preventive service, a key difference from many diagnostic tests.
- **Ordering provider**: The screening must be ordered by the patient's physician or by a qualified non-physician practitioner (e.g., physician assistant, nurse practitioner) who is authorized by state law to perform the service.
- **Billing for diagnostic vs. screening**: It is essential to use G0103 for screening only. If a patient presents with symptoms that warrant a PSA test, the claim should be billed with a CPT code like 84153 (Prostate specific antigen (PSA); total) and a diagnosis code that reflects the patient's symptoms or condition (e.g., R97.21 for elevated PSA, or a specific diagnosis code for prostatic hyperplasia). Mixing screening codes with diagnostic codes can lead to denials.
Do note that no coinsurance, copayment, or deductible applies under Medicare preventive services.
## **Other relevant codes**
- **G0102**: This HCPCS code is for the screening digital rectal examination (DRE). It is often performed in conjunction with the PSA test, but is billed separately. Unlike G0103, Medicare may apply coinsurance and a deductible to G0102.
- **84152, 84153, 84154**: These are CPT codes for diagnostic PSA tests.
- **Z12.5**: As mentioned above, this is the primary ICD-10 diagnosis code for screening for malignant neoplasm of the prostate.
- **Z85.46**: Personal history of malignant neoplasm of prostate. This code is for patients who have a history of prostate cancer and are being monitored after treatment.
Frequently asked questions
Medicare covers one PSA screening test every 12 months for eligible male beneficiaries aged 50 and older.
No. G0103 is for screening only, while 84153 is for diagnostic testing. If screening intent is documented, use G0103 exclusively.
It is always best to check with the specific payer's guidelines. However, G0103 generally does not require a special modifier when billed as a screening service.
