Visit leveling, add-on codes, care management, transitional care and remote monitoring for internists, plus front-desk staff, patient marketing and a claims portal, built on CMS rules and your payers' own policies.
Quick answer
Internal medicine billing services manage the claims an adult practice creates: office visits leveled by medical decision making or time, add-ons such as G2211 and G2212, split/shared hospital visits, and monthly care management, transitional care and remote monitoring. RCM Finder pairs that billing with front-desk assistants, patient marketing and a claims portal, starting with a free audit.
Internal medicine is paid mainly for evaluation and coordination, not procedures. Visit levels, add-on codes, modifiers and monthly services decide what the practice collects.
Office visits have been leveled by medical decision making (MDM) or total time since 2021, Noridian notes. The Medicare Claims Processing Manual extends this to most E/M families from 2023 and requires the full time when time is used. Under the AMA's E/M guidelines, two of three MDM elements must meet the level: problems addressed, data reviewed and risk of management.
Then come the layers: add-on codes G2211 and G2212, and modifiers 25 and FS. Payers do not all treat them the same way.
Monthly services, from care management to remote monitoring, pay only when consent, timing and minutes are documented. This page covers adult internal medicine; see also family practice billing services and geriatrics billing services.
CMS's CY 2026 Physician Fee Schedule final rule fact sheet (October 31, 2025) set the conversion factor at $33.40 for clinicians who are not qualifying APM participants ($33.57 for those who are), up from $32.35. Its -2.5% efficiency adjustment applies to non-time-based services, and E/M visits and care management are exempt. Noridian adds that G2211 can be billed with home or residence visits from 2026.
An internal medicine practice needs the right adult patients, a front desk that tracks consents and discharges, billing that levels visits correctly and software that shows every claim.
Revenue leaks between teams: a missed discharge, an uncharted consent, a G2211 sent on a modifier-25 sick visit. We run all four pillars against one set of payer rules.
Our healthcare digital marketing fills the panel you want, from adults with chronic conditions to new Medicare enrollees, through local SEO, Google Ads and reputation work, with tracking set up to follow HHS guidance.
Our virtual medical assistants run your front desk on your practice's time zone. They verify eligibility, check wellness-visit dates, track consent and work discharge lists. Clinical calls go to your nurses.
Our end-to-end internal medicine revenue cycle management covers coding support, claim scrubbing, denial management and A/R follow-up, with added checks on visit levels, add-on and modifier pairs, FS on shared hospital visits and monthly service periods.
Our practice management system tracks every claim by stage, applies specialty-aware billing logic per claim, checks data completeness before submission and flags payments below the expected amount.
Find where your visit and care management claims leak
We review recent E/M claims, add-ons, care management logs and denials, then show what to fix first. Pricing is quoted after the audit.
Each service family has one rule that decides payment. Codes are described in our own words (the AMA owns CPT descriptors); check the current code set and your contractor's guidance before billing.
| Service family | Code examples (our wording) | Billing rule | Typical denial or audit trigger |
|---|---|---|---|
| Office and outpatient visits | 99202–99205 (new); 99211–99215 (established) | Level by MDM (2 of 3 elements) or the practitioner's total time that day | Note does not support the level; staff time counted |
| Prolonged office time | G2212 (Medicare); 99417 (CPT, some other payers) | One G2212 from 69 minutes with 99215 or 89 with 99205 | 99417 sent to Medicare; plan does not cover G2212 |
| Visit complexity add-on | G2211 with office visits, and home visits from 2026 | Record shows an ongoing care relationship | Modifier 25 visit outside the preventive exception; templated notes |
| Hospital and split/shared visits | 99221–99223 (initial); 99231–99233 (subsequent); 99238, 99239 (discharge) | One inpatient or observation code per date; FS on shared facility visits | No FS; wrong billing practitioner; split/shared used in the office |
| Chronic and principal care management | 99490, 99439, 99491, 99437, 99487, 99489 (CCM); 99424–99427 (PCM) | Consent and care plan; CCM: 2+ chronic conditions expected to last 12+ months; PCM: one high-risk condition | No consent; complex and non-complex CCM in one month; minutes counted twice |
| Advanced primary care management | G0556, G0557, G0558 (by complexity) | Monthly, not time-based; consent; one practitioner paid per month | Level does not match conditions or QMB status |
| Transitional care management | 99495 (moderate MDM, visit within 14 days); 99496 (high MDM, within 7 days) | Contact within 2 business days; medicines reconciled by the visit | Late visit; visit also billed on its own; TCM billed elsewhere |
| Remote physiologic monitoring | 99453 (setup); 99445 (2–15 days); 99454 (16–30); 99457, 99470 (management time) | Established patient; consent; FDA-defined device; one practitioner per 30 days | Billed with RTM; 99445 and 99454 together |

Rules vary by contractor and payer.
We level each visit the way the note supports it. CMS's E/M services booklet (May 2026) says history and exam must be medically appropriate but no longer set the level. Time covers the practitioner's own work that day, not clinical staff time.
Noridian lists 99417 as not valid for Medicare, which uses G2212 for each full 15 minutes past the base code's time range. Commercial plans differ: Ambetter Health's Kansas notice (December 31, 2025) said it would stop covering G2211 and G2212 on April 1, 2026. We keep a per-payer table.
G2211 pays for the ongoing relationship. Noridian says the record must show ongoing care and that templated language may not support it. Medicare does not pay it on a modifier 25 visit, except, since 2025, on the same day as a wellness visit, initial preventive exam, vaccine or other Part B preventive service. See our explainer on modifiers 25 vs 59.
CMS's E/M booklet allows one inpatient or observation code per calendar date. When a physician and an NP or PA in the same group share a facility visit, whoever did the substantive portion bills it with FS. For 2024 onward, Noridian defines that as more than half the total time or the substantive part of the MDM. Office visits cannot be split; see our incident-to billing guide.
Medicare Advantage plans are paid partly on the diagnoses you document. CMS's RADV program page says audits check whether submitted diagnoses are supported by the medical record, and CMS may collect overpayments; its risk adjustment page links to the lists of eligible codes and specialty types. Document each condition you assess with its status and plan, and code only what the note supports. We promise no risk score changes. See our diabetic HCC coding guide.
Monthly services pay only when consent, timing and minutes line up, so we keep each patient on one calendar and bill each service once.
CMS's chronic care management booklet (June 2025) requires two or more chronic conditions expected to last at least 12 months, documented consent, an electronic care plan and 24/7 access. Patients who are new or not seen in a year need an initiating visit first. Principal care management covers one high-risk condition. See our chronic care management coding guide.
Since January 1, 2025, advanced primary care management (G0556 to G0558) has paid monthly without counting minutes. Only one practitioner is paid per month, and the practice must report the Value in Primary Care MVP or join a listed ACO or model. We review APCM and time-based care management with you in the audit.
Under CMS's TCM booklet (August 2025), the 30-day period starts at discharge. The practice must reach the patient or caregiver within 2 business days, through staff who can address needs beyond scheduling; documented attempts can count. The visit must happen within 7 days for 99496 or 14 for 99495, with medicines reconciled by then. Only one practitioner can bill TCM per period.
CMS's remote monitoring booklet (December 2025) requires an established patient for RPM, consent, an FDA-defined device and enough data days in each 30-day period. Only one practitioner can bill per patient in 30 days, and RPM and RTM cannot be billed together. Either can be billed with care management or TCM if time is not counted twice.
The AMA's CPT 2026 release added codes for 2 to 15 days of data and 10 minutes of management; Noridian names them 99445 and 99470. See our telehealth billing guide for virtual visits and endocrinology billing services for diabetes devices.
Check the plan, the last wellness visit, consent for monthly services and any recent discharge before the visit is booked.
The CMS annual wellness visit page allows one visit in a 12-month period; a significant, separately identifiable problem visit that day can be billed with modifier 25. Since January 1, 2026, the CMS-0057-F rule has required Medicare Advantage, Medicaid and CHIP plans to decide prior authorization requests within 72 hours (expedited) or seven calendar days (standard), with a specific denial reason. Drugs are excluded.
| Rule | Source | What the VMA checks before booking |
|---|---|---|
| Wellness visit once in 12 months; not within 12 months of an initial preventive exam | CMS AWV page (2026) | Last wellness or preventive exam date |
| CCM and APCM consent, including cost sharing and one practitioner per month | CMS MLN909188 (2025); CMS APCM page (2026) | Consent on file; asks whether another office provides care management |
| CCM initiating visit if the patient is new or not seen within a year | CMS MLN909188 (2025) | Last visit date; initiating visit booked first |
| TCM contact within 2 business days; visit within 7 or 14 days | CMS MLN908628 (2025) | Discharges worked daily; nurse alerted; visit booked in the window |
| RPM: established patient, consent, one practitioner per 30 days | CMS MLN901705 (2025) | Status and consent; other monitoring programs |
| MA, Medicaid and CHIP prior authorization decided in 72 hours or 7 days | CMS-0057-F (in effect Jan 1, 2026) | Request and due dates logged; follow-up when due |
| Some plans do not cover G2211 or G2212 | Ambetter Health notice (2025) | Plan recorded so billing applies its add-on rules |

Enter your claim volume and denial rate to estimate what your internal medicine practice is losing.
Internal medicine growth comes from local search, reviews and a clear message about who you accept, and the tracking behind it must respect HIPAA.
We build location pages and pages for the conditions you manage, aimed at the panel you want, such as new Medicare enrollees. Review replies never confirm that someone is a patient.
HHS guidance on online tracking says tools on login and appointment pages can collect protected health information, vendors receiving it need a Business Associate Agreement, and a cookie banner is not a HIPAA authorization. A June 2024 court order vacated part of it; we still keep tracking off patient forms without a BAA.
Stay in-house if your coders know MDM leveling and your staff have time for consents and discharge calls. Use a billing-only vendor if claims are the only gap. Choose a combined partner when problems span teams.
| Job | In-house team | Billing-only vendor | Four-pillar partner (RCM Finder) |
|---|---|---|---|
| Visit leveling and add-ons | Each provider's habits | Coded from the note after the fact | Level, add-ons and modifiers checked before submission |
| Care management consent and minutes | A nurse or MA, between visits | Billed if the practice sends logs | VMA tracks consent; RCM bills minutes your clinical team logs |
| Discharge follow-up (TCM) | Whoever sees the hospital notice | Usually left to the practice | VMA works the discharge list; your nurse calls |
| Hospital split/shared visits | Provider remembers FS | Fixed after a denial | FS checked per claim |
| Panel growth and reviews | A separate agency, or nobody | Not included | Marketing tied to new-patient bookings |
| Cost structure | Salaries, benefits, turnover | Varies; ask how fees are set | Quoted after a free practice audit |
Whichever model you choose, track denials by reason, A/R days and visit levels by provider every month.
We start with a free audit and change nothing until you see the findings. We build our billing pipeline around how claims actually move through a practice: registration, charge entry, submission, payment and follow-up. For internal medicine, we add the leveling, add-on and monthly-service checks on this page.
We review recent E/M claims, level patterns by provider, add-ons, care management logs and denials.
We put a Business Associate Agreement in place before accessing patient data. Then we work inside your existing EHR (for example PrognoCIS, eClinicalWorks or athenahealth).
We record how each plan treats G2211, G2212, 99417 and monthly services, then build them into a checklist and portal rules.
VMAs work eligibility, consents and discharge lists. Claims are scrubbed, submitted and worked through denials and A/R.
We review denials by reason, A/R days, TCM visits booked on time and care management enrollment.
Talk to us about your internal medicine practice
Tell us your providers, hospital work and monthly services. We will tell you honestly whether we fit.
Any billing vendor that handles your patients' data is a HIPAA business associate. Get a Business Associate Agreement before any access, and ask how the vendor limits and logs that access.
HHS guidance names billing, claims processing and practice management as business associate work and requires an agreement with safeguards, including for subcontractors. The minimum necessary standard limits use to what each task needs. The Security Rule's technical safeguards require access control, audit controls, integrity controls, person or entity authentication and transmission security.
We use role-based access, audit logging and encrypted (HTTPS) connections, and we put a Business Associate Agreement in place before accessing patient data. For your own side, use our HIPAA compliance checklist for medical practices.
We would rather tell you now than after you sign. Here is where we fit and where we do not.

Probably not a fit if you are
What we would do first if we were running your practice's revenue cycle tomorrow.
A time-based visit needs total minutes for that date; an MDM-based visit needs problems, data and risk in the note.
Plans treat G2211, G2212 and 99417 differently. We keep a table per practice and update it when a plan changes.
Care management, TCM and remote monitoring each have a period and a one-practitioner limit. One calendar per patient stops overlaps.
TCM needs contact within 2 business days. We pull discharges daily so your nurses can call in time.
No consent in the chart means no care management or RPM claim. We confirm it before the first month is billed.
For risk-adjusted plans, each condition should show its status and plan. Audits check the record, not the claim.
They usually cover coding support, claim scrubbing, submission, denial management and A/R follow-up for office and hospital visits. For internists, a good service also checks visit levels against MDM or time, applies add-ons such as G2211 and G2212 by payer, and bills monthly services such as care management, transitional care and remote monitoring. We add front-desk assistants, patient marketing and a claims portal.
Either is allowed for office visits, and for most other E/M families since 2023. Use whichever the note supports better. MDM looks at the problems addressed, the data reviewed and the risk of management; two of the three must meet the level. Time counts the practitioner's total time on the date of the visit, and Medicare requires the full time. Clinical staff time does not count.
Usually not for Medicare. Medicare does not pay G2211 on a visit billed with modifier 25. Since January 1, 2025, the exception is a modifier-25 visit on the same day as an annual wellness visit, an initial preventive exam, vaccine administration or another Part B preventive service. The record must still show an ongoing care relationship. Some commercial plans do not cover G2211 at all.
No. Medicare treats 99417 as not valid and pays G2212 instead, for each full 15 minutes beyond the base visit's time range. With 99215, the first G2212 starts at 69 minutes of total time on the date of service; with 99205, at 89 minutes. Other payers may accept 99417, G2212 or neither, so check each plan's policy.
A split or shared visit is a facility visit that a physician and an NP or PA in the same group both perform. Whoever performs the substantive portion bills it with modifier FS. For 2024 onward, Medicare defines that portion as more than half of the total time or the substantive part of the MDM. Office visits cannot be split or shared; incident-to rules apply there.
Often, yes, if you never count the same time twice. CMS allows chronic care management during the 30-day TCM period, and RPM or RTM, but not both, alongside care management or TCM. Only one practitioner can bill CCM in a calendar month, TCM in its period, or remote monitoring in 30 days. Consent and documentation rules apply to each.
