HCPCS codes covered only if policy criteria and utilization limits met

HCPCS and other supply codes in this policy are covered only when the selection and medical necessity criteria in the policy are met; utilization limits and frequency thresholds noted in the code descriptions apply (for example, one indwelling catheter per month for routine maintenance and specified monthly limits for external catheters and supplies).

• One indwelling catheter per month is medically necessary for routine maintenance (see code descriptions and policy criteria).
• Utilization limits for specific HCPCS codes (e.g., male external catheters, insertion trays, irrigation tubing) are listed in the code table and apply when selection criteria are met.

Device-specific codes require meeting selection criteria (prior auth may apply)

Certain device-specific CPT/HCPCS codes (for example, inFlow CPT 0596T/0597T and HCPCS A4341/A4342, and ureteral stent codes C1875/C2617) are covered only when the policy's selection/medical necessity criteria are met; prior authorization may be required per payer procedures.

• inFlow: CPT 0596T (initial) and 0597T (replacement); HCPCS A4341/A4342 — coverage contingent on meeting inFlow selection criteria.
• Ureteral stents: HCPCS C1875 and C2617 — coverage contingent on clinical indication per policy.

No general prior authorization rule stated for listed urological supplies

The policy excerpt does not specify a blanket prior authorization requirement for the listed urological supply HCPCS codes; check payer-specific prior authorization procedures for potential requirements.

• No explicit prior authorization rule is stated for general urological supplies within these chunks; device-specific codes (see inFlow, stents) are noted separately.

Use external catheters as alternative to indwelling — do not use together

Male external catheters and female external urinary collection devices are considered medically necessary as alternatives to indwelling catheters for members with permanent urinary incontinence; they are not medically necessary when the member also uses an indwelling catheter.

• Male external catheters: generally limited to 35 per month when used as an alternative to indwelling catheters.
• Female devices: limits include no more than 1 meatal cup per week or 1 pouch per day; specialty types may be allowed when clinically justified.
• External devices must not be billed/used concurrently with an indwelling catheter.

inFlow considered alternative to CIC for women with impaired detrusor contractility

The inFlow device is presented as a covered alternative to intermittent catheterization for women with permanent urinary retention due to impaired detrusor contractility when selection criteria are met.

• inFlow is a sterile, single-use intra-urethral valve-pump replaced every 29 days; initial insertion is physician-sized/inserted.
• Clinical trial data (Chen et al.) support inFlow as an alternative to CIC for appropriately selected women.

No step therapy requirements described

The policy does not describe step therapy requirements for inFlow or other urological supplies in the cited excerpts.

• Therapeutic pathway notes describe inFlow as an alternative to CIC, but no formal step therapy/required trial sequence is mandated in these chunks.

inFlow continued-coverage requires in-person re-evaluation (day 31–91)

For continued inFlow coverage beyond the initial 3 months, the treating practitioner must perform and document an in-person re-evaluation between day 31 and day 91 after initiation showing symptom improvement and verified adherence to use.

• Re-evaluation must be an in-person encounter documenting that urinary symptoms are improved and the practitioner verifies adherence to use.
• If re-evaluation occurs after day 91 and shows benefit, coverage resumes from the date of that re-evaluation.
• If required documentation is not present, continued coverage is considered not medically necessary.

Sterile CIC requests lacking required clinical criteria may be medically reviewed/denied

Requests for sterile intermittent catheterization that do not meet the policy's specified clinical criteria (e.g., nursing facility residence, immunosuppressed status, documented VUR on CIC, pregnant spinal cord–injured female, or recurrent UTIs while on clean CIC) are subject to medical review and may be denied.

• Sterile CIC is limited to members meeting at least one listed condition; the policy defines UTI for these criteria (culture >10,000 CFU plus signs/symptoms).
• Requests failing to meet criteria are subject to medical review and potential denial.

Include listed ICD-10 diagnosis codes that meet selection criteria on claims

Use ICD-10 diagnosis codes listed in the policy (for example, N31.x, N32.81, N39.3–N39.498, R32, R33.x, R39.14) on claims when selection criteria are met to support medical necessity for urological supplies.

• Codes such as N32.81 (overactive bladder with impaired detrusor contractility) and R33.x (retention of urine) are specifically associated with inFlow and other device coverage when criteria are met.
• Ensure the diagnosis code on the claim aligns with the policy's selection criteria for the requested supply or device.

No other explicit documentation requirements provided in these excerpts

No additional explicit documentation requirements beyond the inFlow re-evaluation and sterile CIC criteria are provided in these excerpts; the policy history and references are listed but do not add other documentation rules.

• Providers should follow the inFlow re-evaluation and sterile CIC documentation standards noted elsewhere in the policy; no other specific documentation requirements are stated in these chunks.

Irrigation solutions with antibiotics/chemotherapeutic agents (A9270) are non‑covered

Irrigation solutions that contain antibiotics or chemotherapeutic agents (HCPCS A9270) are listed as non-covered and may trigger claim denial if billed.

• HCPCS A9270 is identified as a non-covered item for irrigation solutions containing antibiotics/chemotherapeutic agents.
• Claims for these solutions should not be submitted as covered supplies under this policy.

Lack of required in-person re-evaluation documentation for inFlow risks denial of continued coverage

Continued coverage of the inFlow device beyond the initial 3 months will be considered not medically necessary if the required in-person re-evaluation documentation (symptom improvement and verified adherence) is not present.

• Supplier must stop billing if inFlow usage discontinues; absence of required re-evaluation documentation is a basis for denial of continued supplies.
• If re-evaluation after day 91 documents benefit, coverage resumes from the date of that evaluation.

Document member meets listed clinical criteria to support sterile CIC

Sterile intermittent catheterization documentation must demonstrate the member meets one of the specific clinical indications listed in the policy (e.g., resides in a nursing facility, is immunosuppressed, has radiologically documented vesico-ureteral reflux on CIC, is a pregnant spinal cord–injured female, or has recurrent UTIs on clean CIC).

• For UTI-based criteria, documentation should support culture >10,000 CFU and concurrent listed signs/symptoms.
• For each episode of medically necessary sterile catheterization, document either catheter plus individual lubricant packet or an intermittent catheter kit.

Claims may be denied if coverage rules, code limits, or documentation requirements are not met

Claims for urological supplies are subject to the policy's coverage rules and code-specific frequency/quantity limits; however, this excerpt does not list additional specific denial triggers beyond those already noted (e.g., non-covered items like A9270 or missing required documentation).

• Verify the requested HCPCS/CPT code aligns with the member’s clinical indication and policy selection criteria before billing.
• Adhere to code frequency limits (e.g., insertion trays, catheter monthly allowances, male external catheter monthly maximum) to reduce claim denials.
