A family physician we work with keeps a mental list of the patients who take the most of her time and generate the least revenue. Near the top is a 58-year-old with chronic low back pain after a 2019 fusion, on a stable non-opioid regimen, who calls between visits, needs physical therapy coordination, has a depression screen that keeps coming back positive, and whose 99214 every three months does not begin to cover the work. When we asked whether she was billing chronic pain management, she asked what that was.
That is a common answer. Medicare created the chronic pain management codes G3002 and G3003 in the 2023 physician fee schedule, effective January 1, 2023, specifically to pay for this kind of month-to-month work. Three and a half years later, uptake in primary care remains low, partly because the codes sit in the HCPCS G range where nobody looks, and partly because the requirements sound heavier than they are.
This piece explains the chronic pain management codes G3002 and G3003: who qualifies, what the first visit must include, how to count the monthly 30 minutes, what to document, and how the service fits alongside chronic care management and principal care management.
Key takeaways
- G3002 pays for the first 30 minutes of chronic pain management personally provided by a physician or other qualified health professional in a calendar month; G3003 pays for each additional 15 minutes, and both time thresholds must be met, not approximated.
- The patient must have pain persisting or recurring for more than three months, the initial visit must be in person and at least 30 minutes, and consent must be documented before billing.
- The bundle has defined elements, including a validated pain scale, a person-centered care plan, medication management and coordination with behavioral health; the note has to show them.
- Time counts only when the practitioner does the work; clinical staff time does not count, which is the biggest difference from CCM, and the codes can be billed in the same month as CCM or PCM if no minute is counted twice.
Who qualifies and who can bill
CMS defines chronic pain for these codes as persistent or recurrent pain lasting longer than three months. There is no list of qualifying diagnoses; low back pain, osteoarthritis, neuropathy, fibromyalgia, migraine, post-surgical pain and chronic pain syndrome all qualify when the duration criterion is met. The diagnosis on the claim should reflect both the pain and its cause where known, for example M54.50 (low back pain, unspecified) with G89.29 (other chronic pain), or G89.4 (chronic pain syndrome) when the physician has documented that diagnosis.
Any physician or qualified health professional who can bill Medicare E/M services can bill G3002 and G3003: physicians in any specialty, nurse practitioners, physician assistants, clinical nurse specialists and certified nurse midwives. The codes were written with primary care in mind, not just pain specialists. Only one practitioner can bill the bundle for a patient in a given month, so a patient co-managed by a primary care physician and a pain clinic needs one of them to own it.
Standard Part B cost sharing applies. The patient owes the deductible and 20 percent coinsurance unless a supplemental plan covers it, and the practice must tell the patient that before starting. This is where the consent conversation matters: the patient should understand what the service is, that it recurs monthly, that only one practitioner can bill it, and that they can stop at any time. Document verbal consent in the chart with the date.
What the first visit must include
The initial visit is the gate. It must be in person, with the practitioner and the patient in a clinical setting, and it must last at least 30 minutes. During that visit the practitioner establishes the diagnosis, administers a validated pain rating tool, builds the care plan and obtains consent. After the first month, the face-to-face components can be furnished by telehealth when clinically appropriate, because both codes are on the Medicare telehealth list.
A validated pain tool means a published, tested instrument, not a single "rate your pain 0 to 10" question. The PEG scale (pain intensity, enjoyment of life, general activity) takes about a minute and is the one we see most often in primary care. The Brief Pain Inventory and PROMIS pain interference measures are also accepted. Record the score in a structured field so the trend is visible month to month; the trend is your outcome evidence.
The care plan must be person-centered, which in CMS language means it records the patient's strengths, goals, clinical needs and desired outcomes, not just the physician's treatment list. A plan that reads "continue gabapentin, PT referral" is a treatment list. A plan that reads "Goal: walk to the mailbox daily without stopping by October; barriers: fear of re-injury, sleep disruption; plan: PT twice weekly, sleep hygiene counseling, PEG reassessment monthly" is person-centered, and it also happens to be more useful clinically.
The monthly bundle and the 30-minute rule
G3002 covers a defined set of services in a calendar month: diagnosis; assessment and monitoring; administration of the validated pain scale; development, implementation, revision and maintenance of the care plan; overall treatment management; facilitation and coordination of behavioral health treatment; medication management; pain and health literacy counseling; any necessary chronic pain related crisis care; and ongoing communication and coordination with other practitioners such as physical therapy, occupational therapy, complementary approaches and community-based care. You do not have to perform every element every month, but the plan should address them and the note should show what was done.
The time rule is strict. G3002 requires at least 30 minutes of time personally provided by the billing practitioner in the month; 28 minutes is not billable. G3003 adds each additional 15 minutes and also requires the full 15. There is no cap on G3003 units, but a claim with four or five units every month for every patient will draw a review, so the time log needs to be real.
| Practitioner time in the month | Codes billed | Notes |
|---|---|---|
| Under 30 minutes | Nothing | Time cannot be carried into the next month |
| 30 to 44 minutes | G3002 | Base bundle only |
| 45 to 59 minutes | G3002 + G3003 | One add-on unit |
| 60 to 74 minutes | G3002 + G3003 x 2 | Two add-on units |
| 75 minutes or more | G3002 + G3003 x 3 or more | Expect scrutiny above three units; the log must support it |
What counts is the practitioner's own time on the bundle elements: the visit itself when its content is pain management, reviewing the PT progress note and adjusting the plan, the phone call with the patient about a medication change, the message to the behavioral health clinician, the pain scale review. What does not count: time spent by nurses or medical assistants, time already counted toward a separately billed E/M service for a different problem, and time toward CCM or PCM in the same month.
How G3002 fits with CCM, PCM and E/M
Chronic care management (CCM, codes 99490 and 99491 and their add-ons) pays for care coordination for patients with two or more chronic conditions and allows clinical staff time. Principal care management (PCM, 99424 to 99427) does the same for a single serious condition. Chronic pain management is narrower in subject and stricter in who does the work, and CMS allows it to be billed in the same month as CCM, PCM, behavioral health integration, transitional care management and remote monitoring, provided no minute of time is counted toward more than one service.
In practice, the cleanest arrangement we have seen is this: the practitioner's own pain-related time goes to G3002 and G3003, the care coordinator's time on the patient's diabetes, hypertension and pain goes to CCM, and the two are logged separately. An E/M visit in the same month is billable when it addresses something beyond the pain bundle or when the practitioner documents the E/M work and the pain management work as distinct, with time separated.
Here is a worked example for one month. The patient from the opening sees the physician in person for 25 minutes about pain (PEG reassessed, plan revised), the physician spends 10 minutes reviewing the PT discharge summary and messaging the therapist, and 12 minutes on a phone call adjusting duloxetine. Total practitioner time: 47 minutes. The claim is G3002 plus one unit of G3003. At national Medicare rates when the codes launched, roughly $80 for G3002 and $30 for G3003 before geographic adjustment, that is about $110 for work that previously produced nothing. Over 12 months for one patient it is more than $1,300; over 20 patients it is a meaningful line. Check your locality's 2026 rates in the fee schedule lookup rather than relying on those figures.
Documentation that holds up
Because these are time-based codes with a defined element list, the note needs three things every month: the time (start and stop or total minutes, by activity), the elements addressed, and the pain scale result. A template that carries the care plan forward and prompts for each element takes the burden off memory. The initial visit note should additionally show the in-person setting, the 30-minute duration, the diagnosis, the consent discussion and the cost-sharing explanation.
The audit risk we watch for is cloning: a monthly note that repeats last month's plan word for word with a new date. Reviewers look for evidence of monitoring and revision, and identical notes read as the opposite. The RCM training modules our team teaches on care management codes spend most of their time on exactly this, because the coding is simple and the documentation is where practices fail.
Questions we hear
Can our nurse do the monthly check-in and count it toward G3002?
No. Unlike CCM, chronic pain management time must be personally provided by the physician or qualified health professional. A nurse can gather the pain scale and prepare the chart, but only the practitioner's minutes count toward the 30.
Does the patient have to be on opioids to qualify?
No. The criterion is pain lasting more than three months, regardless of treatment. Many of the best candidates are patients on non-opioid regimens who need coordination with PT, behavioral health and lifestyle changes.
Do Medicare Advantage and commercial plans pay these codes?
Medicare Advantage plans must cover them, though prior authorization rules vary by plan. Commercial coverage is inconsistent; many plans have not adopted the G codes. Verify by payer before enrolling a patient, and load the answer into your billing rules so the front end knows which patients to offer it to. Our billing team keeps a payer grid for care management codes for exactly this reason.
What to do this week
- Run a report of Medicare patients with a pain diagnosis on at least three visits in the past 12 months; that is your candidate list.
- Pick a validated pain tool, add it as a structured field, and set the intake staff to administer it at every visit for those patients.
- Build a G3002 note template with fields for consent, in-person initial visit, time by activity, the element list and the person-centered care plan.
- Decide how CCM and pain management time will be logged separately for patients enrolled in both.
- Schedule the first 30-minute in-person visits for five candidates and bill the first month before expanding.
