Z85.46
ICD-10-CM
Personal History of Prostate Cancer

Understand personal history of prostate cancer diagnosis, including relevant clinical documentation, medical coding (ICD-10 Z85.820, SNOMED CT 78718004), and healthcare implications. Find information on prostate cancer history, past prostate cancer, history of malignancy of prostate, status post prostate cancer, and prostate cancer in remission for accurate medical recordkeeping and coding best practices. Learn about documenting and coding a patient's history of prostate cancer for optimal clinical care and accurate reporting.

Diagnosis Snapshot

Key Facts
  • Definition : Previous diagnosis of prostate cancer, now treated or in remission.
  • Clinical Signs : May be asymptomatic. Elevated PSA possible. Depends on treatment history.
  • Common Settings : Primary care, urology, oncology follow-up.

Code-Specific Guidance

Decision Tree for

Follow this step-by-step guide to choose the correct ICD-10 code.

Is the prostate cancer currently active?

  • Yes

    Do NOT code as personal history. Code the active cancer (e.g., C61.9).

  • No

    Prostate removed?

Documentation Best Practices

Documentation Checklist
  • Prostate cancer diagnosis date
  • Confirmation method (biopsy, imaging)
  • Gleason score if available
  • Stage of prostate cancer (TNM)
  • Treatment history (surgery, radiation)

Coding and Audit Risks

Common Risks
  • Code Z85.42 Specificity

    Risk of incorrect code assignment. Z85.42 should only be used for patients with a documented history of prostate cancer, not suspicion or family history.

  • Active vs. History Confusion

    Risk of coding active prostate cancer (C61) instead of history (Z85.42). Accurate documentation is crucial for proper code selection.

  • Insufficient Documentation

    Risk of lacking detailed clinical documentation to support the diagnosis. Details like treatment dates and type are vital for accurate coding and audit defense.

Mitigation Tips

Best Practices
  • Code Z85.46 for personal hx of prostate cancer, not C61
  • Ensure proper documentation of treatment, stage, and date of diagnosis
  • Query physician for clarity if documentation is unclear or incomplete
  • Regularly audit prostate cancer documentation for CDI and compliance
  • Use standardized vocabulary for consistent and accurate coding

Clinical Decision Support

Checklist
  • Confirm prostate cancer diagnosis documented with ICD code (e.g., Z85.46)
  • Verify past treatments documented (surgery, radiation, hormone therapy)
  • Check date of diagnosis and treatment completion for accurate staging
  • Review pathology report for Gleason score and other relevant details

Documentation Templates

The patient presents with a personal history of prostate cancer.  Initial diagnosis of prostate adenocarcinoma was established on [Date of Diagnosis] with a Gleason score of [Gleason Score] at the time of diagnosis.  The clinical stage was determined to be [Clinical Stage, e.g., TNM Stage].  Initial treatment consisted of [Treatment Description, e.g., radical prostatectomy, radiation therapy, brachytherapy, active surveillance].  Prostate-specific antigen (PSA) at diagnosis was [PSA value, e.g., X ngml].  Current PSA is [Current PSA Value, e.g., X ngml].  The patient reports [Symptoms, e.g., being asymptomatic, experiencing urinary frequency, urgency, nocturia, or erectile dysfunction]. Physical examination reveals [Findings, e.g., normal digital rectal exam, palpable nodule].  Assessment includes personal history of prostate cancer, currently [Status, e.g., in remission, with biochemical recurrence, with metastatic disease].  Plan includes [Plan, e.g., continued surveillance with PSA monitoring every [Frequency], ongoing androgen deprivation therapy, referral to oncology, imaging studies such as bone scan or CT scan].  Patient education provided regarding prostate cancer management, including discussion of potential side effects of treatment and importance of follow-up care.  Coding considerations include ICD-10 code Z85.820 for personal history of prostate cancer, and additional codes for any current symptoms, complications, or treatment.  Medical billing should reflect the evaluation and management services provided, as well as any procedures performed.
