55700

🔬 CPT Code 55700 - Biopsy, Prostate; Needle or Punch, Single or Multiple, Any Approach

---

📋 Code Description

Full Official Description: Biopsy, prostate; needle or punch, single or multiple, any approach

CPT 55700 describes a diagnostic needle or punch biopsy of the prostate gland, performed via any surgical approach. The procedure may involve a single core or multiple cores (systematic or targeted) and encompasses all standard approaches including:

• Transrectal (most common; typically ultrasound-guided)
• Transperineal (increasingly preferred for reduced infection risk)
• Transurethral (less common, occasionally used intraoperatively)

The purpose is histopathologic tissue sampling to evaluate for prostate adenocarcinoma, high-grade prostatic intraepithelial neoplasia (HGPIN), atypical small acinar proliferation (ASAP), or other prostate pathology. A standard systematic biopsy protocol often involves 10-12 cores, but 55700 is reported once regardless of core number, unless a stereotactic template-guided saturation biopsy with ≥10 cores is performed (see 55706).

✅ What’s Included

55700 bundles the following into a single billable unit:

• Positioning and draping of the patient
• Digital rectal exam (DRE) performed at the time of biopsy (if done as part of the same session)
• Local anesthetic injection (e.g., periprostatic nerve block) when performed as part of the biopsy approach
• Needle insertion and tissue core extraction — single or multiple passes, any number of cores
• Specimen preparation and labeling for pathology submission
• Standard post-procedure care within the 0-day global period

💡 HCC Details - C61

C61 - Malignant Neoplasm of Prostate

• HCC Category: HCC 12 — Prostate, Testicular, and Other Male Genital Cancers
• HCC Risk Adjustment Factor (RAF): ~0.149 (CMS-HCC v28 model)
• Impact: Flags the patient as a high-complexity, high-cost beneficiary for risk-adjusted payment models (Medicare Advantage, ACO, etc.)
• Documentation Tip: Must be actively treated or monitored to be coded as current; if in remission, refer to personal history codes (Z85.46)
• Coding Clinic Guidance: Code C61 is appropriate even during active surveillance; “active” does not require ongoing chemotherapy or radiation

🏨 MS-DRG (Inpatient Context)

55700 is predominantly performed in the outpatient or office setting. However, when a prostate biopsy is performed or documented during an inpatient admission (e.g., workup for urinary obstruction, post-complication, or comorbid acute illness), the associated ICD-10-PCS procedure code should be reported on the UB-04, not the CPT code.

ICD-10-PCS Equivalent (Inpatient)

ICD-10-PCS	Description
0VB07ZX	Excision of Prostate, Via Natural or Artificial Opening, Diagnostic
0VB03ZX	Excision of Prostate, Percutaneous, Diagnostic
0VB04ZX	Excision of Prostate, Percutaneous Endoscopic, Diagnostic

PCS Root Operation: Excision (B) — cutting out or off, without replacement, a portion of a body part Qualifier: X = Diagnostic (biopsy)

Associated MS-DRGs (When Biopsy Drives Admission or Occurs Inpatient)

MS-DRG	Description	Partition
729	Other Male Reproductive System O.R. Procedures with MCC	Surgical
730	Other Male Reproductive System O.R. Procedures with CC	Surgical
731	Other Male Reproductive System O.R. Procedures without CC/MCC	Surgical
742	Uterine and Adnexa Proc for Non-Malignancy with CC/MCC (not applicable)	—
969	HIV with Extensive O.R. Procedure with MCC (if HIV+)	—

Warning

⚠️ MS-DRG assignment for inpatient prostate biopsy is heavily influenced by the principal diagnosis and CCs/MCCs. A patient admitted for urinary retention (R33.9, N40.1) with an incidental biopsy may DRG differently than one admitted specifically for a prostate mass workup (N42.89, C61).

📝 Coding Examples

---

🟢 Example 1 - Standard Outpatient Transrectal Biopsy with Ultrasound Guidance

Clinical Scenario: A 64-year-old male presents to urology clinic with a PSA of 7.2 ng/mL (previously 4.8). DRE reveals a firm right lobe. A 12-core transrectal ultrasound-guided prostate biopsy is performed. The radiologist performs and documents real-time ultrasound guidance with a full supervision and interpretation report.

CPT Codes:

• 55700 - Prostate biopsy, needle, 12 cores, transrectal approach
• 76942 - Ultrasonic guidance for needle placement, imaging S&I (append modifier 26 if physician does not own equipment)

ICD-10-CM Codes:

• R97.20 - Elevated PSA (primary indication)
• N40.0 - BPH without LUTS (documented comorbidity)

Notes: 55700 is reported once regardless of 12 cores obtained. Do not bill 55700 x12.

---

🟢 Example 2 - MRI-Fusion Targeted Biopsy

Clinical Scenario: A 59-year-old male with prior negative TRUS biopsy and PIRADS 4 lesion on mpMRI undergoes MRI-ultrasound fusion-guided targeted biopsy (4 targeted cores to the lesion + 10 systematic cores).

CPT Codes:

• 55700 - Prostate biopsy, needle, multiple cores, transrectal (systematic + targeted)
• 76942 - Ultrasound guidance (if TRUS component separately documented)
• 77021 - MRI guidance for needle placement, imaging supervision & interpretation (if the MRI fusion targeting is performed with real-time MRI)

ICD-10-CM Codes:

• R97.20 - Elevated PSA
• D40.0 - Neoplasm of uncertain behavior (PIRADS 4 lesion on MRI)

---

🟢 Example 3 - Re-biopsy After HGPIN

Clinical Scenario: A 67-year-old male had a prior biopsy showing high-grade PIN. Repeat 12-core transperineal biopsy is performed under local periprostatic block. No ultrasound guidance is used.

CPT Codes:

• 55700 - Prostate biopsy, needle, transperineal approach

ICD-10-CM Codes:

• N42.39 - Other prostatic intraepithelial neoplasia (HGPIN)
• R97.20 - Elevated PSA (if also present and documented)

---

🟢 Example 4 - Inpatient Biopsy During Hospitalization (Inpatient Coding)

Clinical Scenario: A 72-year-old male is admitted for acute urinary retention (N13.8 - ureteral obstruction vs. R33.9). During workup, the urologist performs a transrectal needle biopsy. Path returns prostate adenocarcinoma, Gleason 7.

ICD-10-CM (UB-04):

• Principal Dx: R33.9 - Retention of urine, unspecified
• Secondary Dx: C61 - Malignant neoplasm of prostate (found during stay → sequence as secondary per UHDDS guidelines)
• N40.1 - BPH with LUTS (contributing)

ICD-10-PCS Procedure:

• 0VB07ZX - Excision of Prostate, Via Natural or Artificial Opening, Diagnostic

MS-DRG: Likely 730 or 729 depending on MCC/CC status; C61 as secondary may act as CC/MCC depending on grouper version.

🏥 Inpatient Coder Tip: When cancer is discovered during an admission for another reason, sequence the admission’s primary reason as the principal diagnosis per the UHDDS definition — the condition determined after study to be chiefly responsible for the admission. C61 would be secondary unless the patient was admitted specifically for the prostate cancer workup.

⚠️ Common Coding Pitfalls

• ❌ Do not report 55700 multiple times for multiple cores — it is a per-session code
• ❌ Do not confuse 55700 (needle/punch biopsy) with 55706 (stereotactic template-guided saturation biopsy ≥10 cores transperineal) — 55706 has specific criteria
• ❌ Do not report 76942 without a documented supervision and interpretation report — payers will deny without it
• ❌ Do not code C61 from pathology alone without physician confirmation in the medical record (particularly for inpatient)
• ✅ When the approach changes mid-procedure (e.g., transrectal to transperineal), still report 55700 once — “any approach” is inclusive
• ✅ MRI/US fusion guidance is a separate reportable service with proper documentation — do not bundle into 55700
• ✅ Periprostatic nerve block (anesthetic injection) is included in 55700 — do not separately bill injection codes
