CPT code 62370 – Intrathecal pump refill and reprogramming by a physician or QHP

Key takeaways

CPT code 62370 covers analysis, reprogramming and refill of an implanted intrathecal or epidural pump when the service requires physician or QHP skill.

CPT 62369 includes the same refill but applies when the service does not need physician or QHP skill, such as an RN refill.

A visit with no refill is 62368 (analysis and reprogramming) or 62367 (analysis only), and only one of 62367 to 62370 is reported per encounter.

Documentation must record pump settings before and after, drug name, concentration, lot number, both volumes, and why physician or QHP skill was needed.

Billing software such as Pabau checks each pump claim for missing or invalid details before it reaches the payer.

CPT code 62370: definition and procedure components

The American Medical Association describes CPT code 62370 as electronic analysis of a programmable implanted pump for intrathecal or epidural infusion, with reprogramming and refill. The analysis includes evaluation of reservoir status, alarm status and drug prescription status. The descriptor ends with a qualifier: the service requires the skill of a physician or other qualified health care professional.

The code is owned by the AMA and sits in the Surgery section of the CPT code set. Within it, 62370 falls in the nervous system range for spinal reservoir and pump services.

Four elements must all be present in the encounter for 62370 to apply. When any one of them is missing, a different code in the family describes the visit.

The drug in the pump is billed separately from the procedure. Office claims report baclofen with J0475 or J0476 and morphine with J2275. Hospital outpatient claims under HOPPS use the applicable C-code. The 62370 line never carries the drug cost, so the drug goes on its own claim line.

What happens during a CPT 62370 encounter

A typical intrathecal pump management visit runs 30 to 60 minutes and follows a defined clinical sequence. Knowing the encounter helps coders confirm that documentation captures every billable element before the claim goes out.

1. Device interrogation: the physician connects the programmer, such as the N’Vision clinician programmer for Medtronic SynchroMed II or the clinician programmer for the Flowonix Prometra. They retrieve current settings, the drug delivery log, battery life, and alarm history.
2. Clinical assessment: review of patient symptoms, pain scores, spasticity rating, or other outcome measures since the last visit. Settings decisions are based on this review.
3. Parameter adjustment and electronic reprogramming: new flow rate, bolus dose, or schedule programmed into the device via wireless telemetry. The new parameters are confirmed on-screen before programming is finalized.
4. Reservoir refill: the physician or QHP cleans the access port site and inserts a Huber non-coring needle through the skin into the fill port. They withdraw the residual drug volume and inject the freshly prepared drug solution. If an RN or other clinical staff do the refill without needing physician skill, the visit is 62369 instead.
5. Documentation and confirmation: the pump status is checked on the programmer after the refill. The physician or QHP records all parameters and drug details before the patient leaves.

Clinical indications: when CPT 62370 is used

Intrathecal baclofen pump programming and morphine infusion for chronic pain represent the two most common clinical contexts for 62370 encounters. Payers require a supported ICD-10 diagnosis that maps to an approved indication in the Medicare contractor’s policy or the commercial payer’s policy. For Noridian’s JE and JF jurisdictions, that is Billing and Coding article A55323 (LCD L33461).

• Intractable spasticity: multiple sclerosis (G35), cerebral palsy (G80.x), spinal cord injury (G82.x), traumatic brain injury. Baclofen is the approved intrathecal drug for spasticity management.
• Chronic non-malignant pain: failed back surgery syndrome, complex regional pain syndrome, other chronic pain (G89.29). Morphine (Infumorph) and ziconotide (Prialt) are common agents.
• Cancer-related pain: neoplasm-related pain (G89.3) in patients with solid tumors or hematologic malignancies where systemic opioids are inadequate or cause unmanageable side effects.
• Post-stroke spasticity or arachnoiditis: less common, but covered under specific LCD criteria when conservative measures have failed. A documented clinical trial of intrathecal therapy is also required.

Billing and Coding article A55323, “Implantable Infusion Pumps for Chronic Pain”, is linked to LCD L33461 and published by Noridian for JE and JF. Other Medicare Administrative Contractors (MACs) publish their own. Failure to match the submitted ICD-10 to an LCD-covered indication is one of the most common denial triggers for this code family.

CPT 62370 vs. 62369: choosing the right code

CPT 62369 and 62370 describe the same service: electronic analysis, reprogramming and a reservoir refill. Both codes include the refill. What separates them is whether the service required the skill of a physician or other qualified health care professional.

Report 62370 when it did, and the note shows a physician or QHP doing work that needed that skill. Report 62369 when it did not, for example when an RN or other clinical staff performed the refill. 62369 is a standalone code, not an add-on to any other code.

If the reservoir was not refilled, neither code applies. Report 62368 for analysis with reprogramming, or 62367 for analysis alone. Report only one code from 62367 to 62370 per encounter, the one that matches the work performed. The matrix below maps each combination of work to its code.

Related intrathecal pump CPT codes

62370 belongs to a family of codes covering the full lifecycle of implanted infusion pump management. The pump itself is implanted under 62362, and each later management visit is billed from the analysis codes. The four analysis codes, 62367 to 62370, are mutually exclusive for a single encounter.

Documentation requirements for CPT 62370

A chart note that supports 62370 billing must show that all four elements occurred and satisfy clean claim requirements before submission. The following elements are required for audit defense and payer compliance.

• Device identification: pump manufacturer, model, and serial number (or implant ID).
• Current settings: flow rate, daily dose, bolus parameters, and mode (continuous, bolus, flex) as interrogated at the start of the visit.
• New programmed parameters: every value that was changed, with the previous value for comparison. If no change was made to a parameter, that should be noted too.
• Drug details: drug name (such as baclofen or morphine sulfate), concentration (mg/mL), lot number, and expiration date.
• Volumes: volume of drug withdrawn from the reservoir (residual), volume of new drug injected, and calculated remaining reservoir volume after refill.
• Physician or QHP attestation: the note must name the physician or other QHP who performed the service and carry their signature. It must also say why the visit needed that skill, such as a dose titration decision or an assessment of side effects. A note that shows only an RN or other clinical staff doing the refill supports 62369, not 62370.
• Supporting ICD-10 diagnosis: the claim must carry at least one diagnosis covered by your MAC’s policy or the commercial payer’s equivalent. For Noridian JE/JF, that policy is A55323.

Auditors most often find the drug lot number or the volumes missing from the note. A superbill documentation checklist built into the visit note catches both at the point of care, before the claim reaches billing review.

ICD-10 diagnosis codes commonly paired with CPT 62370

The claim must include a supported diagnosis from the ICD-10-CM code set that maps to an approved indication in the payer’s policy. The codes below are common pairings. For Noridian JE/JF claims, check each one against Billing and Coding article A55323 (LCD L33461), since other MACs publish their own lists.

Z96.89 is a supplemental code and should always be paired with a primary clinical diagnosis, not billed alone. MAC-specific policies may expand or restrict this list. Verify it against the current policy for your jurisdiction before submitting.

Medicare reimbursement and payment rates for CPT 62370

Medicare pays for 62370 under the Medicare Physician Fee Schedule (MPFS). Use the CMS Physician Fee Schedule lookup tool for current locality-specific rates, which CMS updates each January.

The XXX indicator means the global surgery concept does not apply to 62370. Same-day services follow NCCI edits and the modifier 25 rules instead. These are 2026 CMS values. For locality-adjusted total RVU values and exact dollar amounts, use the FastRVU 2026 RVU lookup tool.

Payer coverage policies and prior authorization requirements

Medicare covers ongoing intrathecal pump management when the original implant met coverage criteria. In Noridian’s JE and JF jurisdictions, the coding rules sit in Billing and Coding article A55323 (LCD L33461), and other MACs publish their own. The patient must also continue to meet the stated clinical indications. Medicare does not typically require prior authorization for the ongoing management visit, as distinct from the implant surgery. Commercial payers frequently do. Confirming insurance eligibility verification and PA status before the appointment prevents same-day denials.

• Medicare (A55323 and LCD L33461 for Noridian JE/JF): covers ongoing management visits when the implant was placed for an approved indication. The documentation must also support continued medical necessity. No routine prior auth for management visits, but claims are reviewed for LCD compliance.
• Aetna (CPB 0161): requires prior auth for the initial implant. Later management visits are generally covered without per-visit PA if the original auth is on file and the indication is unchanged.
• BCBS plans: policies vary by state affiliate. Mississippi BCBS has a specific intrathecal morphine policy. Verify coverage with each affiliate separately.
• Medicaid (state plans): ForwardHealth (Wisconsin Medicaid) has a published intrathecal pump coverage policy. Other state programs vary, so contact the state Medicaid agency or its provider portal directly.
• Commercial plans generally: expect prior auth documentation to include the original trial records, implant operative report, and current clinical status notes at each major reassessment.

Common denial reasons for CPT 62370 and how to prevent them

62370 denials cluster around five predictable causes. Each has a specific prevention action that can be built into the pre-claim workflow. Strong denial management workflows fix the step that produced each denial, so the same error stops recurring on the next pump claim.

Bundling rules and modifier guidance for CPT 62370

The National Correct Coding Initiative (NCCI) governs which services can be billed alongside 62370 on the same date of service. Pabau, the practice management platform we build, includes claims management software that scrubs each claim for missing or invalid details before it goes out.

• Same-day E&M with modifier 25: a separately identifiable E&M service can be billed on the same day as 62370. It qualifies only when it addresses a distinct problem beyond the routine pump management. Modifier 25 must be appended to the E&M code, and the chart note must document the separate problem. Billing a routine pump visit E&M alongside 62370 without modifier 25 will trigger an NCCI edit denial.
• Drug billing (J-codes / C-codes): the drug delivered through the pump must be billed separately on a different claim line. Office claims use J0475 or J0476 for baclofen and J2275 for morphine. Hospital outpatient (HOPPS) claims use the applicable C-code. Never bundle the drug cost into the 62370 procedure line.
• Multiple pump services same day: report only one of 62367, 62368, 62369 and 62370 per encounter, the one that matches the work performed. 62369 and 62370 include the same analysis, reprogramming and refill. 62370 applies only when that work required physician or QHP skill. Do not report 95990 or 95991 with any of these four codes.
• Global surgery period: 62370 carries a global indicator of XXX, so the global surgery concept does not apply. There is no post-operative window to track after a pump visit.

For complete and current NCCI edit tables, the AAPC Codify CPT lookup provides NCCI column I/II edit data alongside the code descriptor. Pair this with your clearinghouse’s claim validation to catch edit conflicts before they reach the payer.

How claims management software reduces errors for CPT code 62370

Coding errors on pump visits usually start in the chart note. A free-text note rarely says who performed the refill or why it needed a physician, so the coder has to guess between 62369 and 62370.

In Pabau, the pump visit can run on a treatment note template. Its required fields cover the drug, lot number, volumes and who did each step. The coder reads the answer instead of guessing it.

Pabau’s claims management software then scrubs each claim for missing or invalid details before it goes out. In the US, it checks eligibility through Claim.MD before the visit and submits claims to thousands of payers. A rejected pump claim is flagged as needing action, with the reason shown, so your team can correct and resubmit it.

The result is fewer pump claims coded on guesswork, and a record that holds up when a payer asks who did the work.

Conclusion

Both 62369 and 62370 include a refill. Once the reservoir is filled, the code turns on one fact: whether the visit needed a physician or QHP, as the chart note shows it.

Billing 62370 for every refill, including nurse-run visits, puts each of those claims at audit risk. Defaulting to 62369 when a physician did skilled work under-codes the visit. Both problems share one fix: a pump note that records who did each step and why.
