CPT Code 00914: TURP anesthesia billing and reimbursement guide

Key Takeaways

CPT code 00914 describes anesthesia for transurethral procedures, specifically transurethral resection of the prostate (TURP), within the perineum anesthesia range 00902-00952.

The base unit value for CPT code 00914 is 5.0, per the VA Community Care fee schedule and CMS data. Total reimbursement uses the B+T+M formula (base units + time units + modifiers).

When the surgeon performs both the TURP (CPT 52601) and the anesthesia, separate billing of CPT code 00914 is inappropriate: CMS bundles it into 52601 when performed by the same physician.

CPT code 00914 is the anesthesia billing code for transurethral resection of the prostate (TURP), the standard surgical treatment for benign prostatic hyperplasia (BPH) and, in some cases, prostate cancer. It sits within the AMA’s perineum anesthesia range (00902-00952) and carries a base unit value of 5.0.

Two errors show up constantly in TURP anesthesia claims: billing 00914 separately when the operating surgeon also administers the anesthesia, and confusing it with the lower-intensity 00910 code used for diagnostic cystoscopy. This guide covers the base-unit-plus-time-plus-modifier reimbursement formula, the physical status and medical direction modifiers that apply, and the CMS bundling rule that determines when 00914 can be billed on its own.

CPT code 00914: definition and clinical description

CPT code 00914 describes anesthesia services for transurethral procedures on the prostate, primarily the transurethral resection of the prostate (TURP). It falls within the American Medical Association’s perineum anesthesia subsection, covering code range 00902 through 00952, per the AMA’s CPT code set overview. It’s a distinct code from CPT codes for coaching services, which apply to behavioral health billing rather than surgical anesthesia.

The full AMA descriptor reads: “Anesthesia for transurethral procedures (including urethrocystoscopy); transurethral resection of prostate.” That parenthetical matters: urethrocystoscopy procedures within the same transurethral access are included in the descriptor, but the 00914 code is specifically reserved for the prostate resection itself.

TURP relieves urinary obstruction caused by benign prostatic hyperplasia (BPH) or, in some cases, prostate cancer. Diagnosis is often confirmed by a prostate biopsy, billed under 55700, and elevated PSA findings coded as R97.20 frequently prompt that workup. The anesthesiologist or qualified non-physician anesthetist manages the patient through a procedure that typically runs 45 to 90 minutes.

Coders sometimes encounter shorthand references to CPT code 00914 as simply “removal of prostate” in quick-reference cheat sheets. That description is technically incomplete. The full descriptor emphasizes the transurethral approach and includes the procedural category context. Use the full AMA descriptor language when documenting and billing to avoid unnecessary payer queries.

Base units, time units, and the B+T+M reimbursement formula

Anesthesia billing does not follow the standard RVU model used for most surgical and evaluation codes. Instead, reimbursement for CPT code 00914 is calculated using the B+T+M formula: base units plus time units plus modifying units. Each component contributes to the total unit count, which is then multiplied by the applicable anesthesia conversion factor.

The base unit value of 5.0 for CPT code 00914 is confirmed by the VA Community Care professional anesthesia nationwide base units table. That table lists 00914 explicitly as “ANESTHESIA TRANSURETHRAL RESECTION OF PROSTATE” at 5.0 base units. For comparison, a bladder surgery code (00910) carries only 3 base units, reflecting the relatively lower procedural intensity of cystoscopy versus TURP.

Time units are the variable component most likely to trigger documentation disputes. Anesthesia time begins when the anesthesiologist assumes responsibility for the patient and ends when the patient is safely transferred to post-anesthesia care. Every 15 minutes equals one time unit. Partial units are typically rounded to the nearest full unit per payer policy, though some payers allow billing in tenths of units. Document start and stop times precisely in the anesthesia record.

Physical status modifiers for CPT 00914

Physical status modifiers (P1 through P6) reflect the patient’s health condition at the time of surgery. The American Society of Anesthesiologists (ASA) defines these classifications, and they directly affect reimbursement for CPT code 00914. Not all payers recognize all physical status modifiers, so always verify payer-specific policies before appending them.

• P1: Normal healthy patient. No additional modifying units. Standard TURP candidate with no comorbidities.
• P2: Patient with mild systemic disease. No additional modifying units under most fee schedules.
• P3: Patient with severe systemic disease. Adds 1 modifying unit. Common for BPH patients with controlled cardiovascular disease or diabetes.
• P4: Patient with severe systemic disease that is a constant threat to life. Adds 2 modifying units.
• P5: Moribund patient not expected to survive without the operation. Adds 3 modifying units.
• P6: Brain-dead patient for organ donation purposes. Not applicable to routine TURP cases.

Medicare and many commercial payers do not separately reimburse for physical status modifiers P1 and P2 because they add zero modifying units. For P3 and above, documentation must clearly support the classification. A patient chart noting “poorly controlled hypertension, type 2 diabetes, moderate CKD” supports a P3 designation. A chart noting only “hypertension, well-controlled on medication” typically does not rise to P3.

Modifier usage for CPT code 00914 billing

Medical direction and medical supervision modifiers are among the most consequential billing variables for CPT code 00914. The correct modifier depends entirely on who delivers the anesthesia and under what supervisory arrangement. Misapplied modifiers are one of the top triggers for claim denials and OIG audit scrutiny.

When QK and QX modifiers apply, both the directing anesthesiologist and the CRNA bill CPT code 00914 with their respective modifiers on separate claims. Medicare pays each at 50% of the allowable, resulting in a combined total of 100%. The critical compliance point: the anesthesiologist must fulfill all seven medical direction requirements during the case, including pre- and post-anesthesia evaluations, being immediately available, and not directing more than four concurrent procedures.

Modifier G8 (monitored anesthesia care for a patient with a history of severe cardiopulmonary condition) and Modifier G9 (monitored anesthesia care for a patient who was or is expected to become a surgical or anesthesia risk) also appear in TURP anesthesia scenarios. Append these when monitored anesthesia care (MAC) is used and the patient meets the clinical criteria. Keep HIPAA-compliant clinical documentation of the MAC rationale in the patient record.

CMS bundling rules: CPT 00914 and surgical code 52601

A frequently misunderstood billing rule affects practices where a single physician performs both the surgical and anesthesia components of a TURP procedure. When the surgeon performs the TURP itself, billed as CPT 52601, and also administers the anesthesia, CPT code 00914 cannot be reported separately. General CMS and National Correct Coding Initiative (NCCI) policy bundles anesthesia into the surgical code whenever the operating surgeon personally provides it, because a surgeon cannot separately bill for anesthesia they administer during their own procedure. If a second-stage resection is required, it’s reported as CPT 52601 with modifier 58, and the same bundling principle applies.

This bundling rule does not apply when a separate, qualified anesthesiologist or CRNA provides the anesthesia services. In that scenario, CPT code 00914 is appropriately billable by the anesthesia provider. The distinction is straightforward in most hospital and ambulatory surgery center settings, where the surgical and anesthesia teams are separate. In smaller or rural settings, a surgeon may attempt to bill both codes. Ensure your compliance documentation checklist includes a physician-role verification step before submitting 00914 alongside 52601 claims.

ICD-10-CM diagnosis codes paired with CPT 00914

Medical necessity for CPT code 00914 requires pairing with an appropriate ICD-10-CM diagnosis code. Payers use these pairings to validate that the anesthesia service was clinically indicated. The three most common diagnoses driving TURP procedures are:

• N40.1 (Benign prostatic hyperplasia with lower urinary tract symptoms): The most frequent diagnosis paired with CPT 00914. Documents BPH significant enough to require surgical intervention.
• N40.0 (Benign prostatic hyperplasia without lower urinary tract symptoms): Used when BPH is confirmed but the primary indication is anatomical rather than symptomatic obstruction.
• C61 (Malignant neoplasm of the prostate): Applicable when TURP is performed as part of prostate cancer management, including palliative debulking procedures.

Confirm with the surgical team which primary indication is driving the procedure before finalizing the diagnosis code on the anesthesia claim: submitting C61 when the operative report references N40.0 creates a documentation mismatch that payers flag on audit. Some TURP patients also carry a coexisting urethral disorder such as those in the N37 category, which should be listed as a secondary diagnosis if it affected the surgical approach.

Secondary diagnoses matter too. A patient with uncontrolled diabetes (E11.65) or significant cardiac disease (I25.10) that influences the anesthesia approach should have those codes listed. ICD-10 code pairing for clinical documentation supports the physical status modifier you’ve appended and provides the payer with a complete clinical picture. Comorbidity codes are also what distinguish a P2 from a P3 designation in the eyes of an auditor.

Related transurethral anesthesia codes

CPT code 00914 sits within a family of transurethral and perineal procedure codes. Knowing the adjacent codes prevents upcoding errors and helps coders select the right code when the operative report describes a procedure other than TURP.

Anesthesia base units vary by anatomical region and procedure complexity: 00600 covers cervical spine procedures, while 00102 covers cleft lip repair, illustrating how the base unit scale shifts outside the perineum anesthesia range.

The most common confusion involves 00910 versus CPT code 00914. Code 00910 is the general transurethral anesthesia code, covering urethrocystoscopy and procedures “not otherwise specified.” It carries only 3 base units because routine cystoscopy is less complex than TURP. If the operative report documents a urethrocystoscopy that incidentally identified a prostatic condition but did not proceed to resection, 00910 is correct. If resection occurred, use 00914. Never upcode to 00914 when the procedure was diagnostic only.

CPT code 00908 is also occasionally confused with 00914. The distinction is approach: 00908 covers open or other non-transurethral approaches to prostate removal, carrying 6 base units. CPT code 00914 is specifically transurethral. Review the surgical approach in the operative report before selecting between these two codes. For comparison, you can also review how IVF procedure billing codes handle procedure-specific differentiation within a family of related codes.

Documentation requirements and medical necessity

Claims for CPT code 00914 require documentation that goes beyond the anesthesia record itself. Payers increasingly request supporting documentation during pre-payment review or post-payment audit, particularly for outpatient or ambulatory surgery center settings.

• Pre-anesthesia evaluation: Documents the patient’s ASA physical status, relevant comorbidities, airway assessment, and anesthesia plan. Required for medical direction modifiers (QK, QY) to be valid under Medicare rules.
• Intraoperative anesthesia record: Shows start and stop times, vital signs, drugs administered, and any complications. This is the primary source for time unit calculation.
• Post-anesthesia evaluation: Documents the patient’s condition on transfer to recovery. Required alongside the pre-anesthesia evaluation when billing medical direction modifiers.
• Operative report: Confirms the procedure performed, the approach (transurethral), and the clinical indication. Cross-references the ICD-10-CM code on the anesthesia claim.
• Physician attestation (for QK/QX cases): The anesthesiologist must document fulfillment of all seven medical direction requirements for each concurrent case.

Using digital intake forms integrated with your practice management system helps capture pre-anesthesia evaluation data in a structured, auditable format. Storing these records electronically also simplifies retrieval during payer audits and supports the ICD-10 code sequencing rules that determine principal versus secondary diagnosis on claims.

Pre-authorization requirements vary by payer. Medicare does not generally require prior authorization for TURP anesthesia when performed in an approved facility, but many commercial plans do. Verify authorization status before the procedure date. Billing for CPT code 00914 without confirmed authorization on a plan that requires it leads to automatic denial that is difficult to overturn on appeal without documented good-faith efforts to obtain approval.

Reimbursement rates and fee schedule considerations

Specific dollar reimbursement figures for CPT code 00914 vary by payer, geography, and plan year. Publishing a single dollar figure as “the rate” would be misleading. Instead, the correct approach is to calculate reimbursement using the B+T+M formula against your payer’s current conversion factor.

For Medicare, use the CMS Physician Fee Schedule lookup tool to find the current anesthesia conversion factor for your geographic region. The Medicare national base anesthesia conversion factor changes annually. For 2026 rates, verify directly with CMS; published figures from third-party sources should always be cross-checked against the official fee schedule. You can also use FastRVU’s 2026 RVU lookup to access work, PE, and malpractice RVU values.

A practical benchmark: a TURP case averaging 60 minutes produces approximately 4 time units (15 minutes each). For a P1 patient, total units = 5 (base) + 4 (time) + 0 (modifier) = 9 units. For a P3 patient, total units = 5 + 4 + 1 = 10 units. Multiply your total units by the payer’s conversion factor to arrive at the allowable amount. Arizona ICA fee schedules from 2020-2021 listed CPT code 00914 at 5 base units with a $305 base amount, but those figures are several years old. Confirm current rates with your state’s workers’ compensation or injury compensation authority.

Commercial payers often negotiate rates above Medicare, particularly for anesthesiologists at academic medical centers or high-volume surgical facilities. Claims management software that tracks expected versus received reimbursement by CPT code helps identify persistent underpayments before they become write-offs.

Conclusion

Accurate billing for CPT code 00914 depends on three things: the right base unit value (5.0), the right modifier for the provider arrangement, and documentation that substantiates every component of the claim. The CMS bundling rule with 52601 and the 00910 versus 00914 distinction are the two most common sources of billing errors in TURP anesthesia cases.
