Medical Nutrition Therapy Billing Services
Dietitian claims often fail for reasons outside the visit itself. Medicare pays for MNT only with a treating physician's referral, only for covered diagnoses and only up to an annual hour limit, and commercial plans set their own versions of all three. Qualigenix bills medical nutrition therapy (MNT) for registered dietitians and nutrition practices, covering initial assessments, follow-up visits, group sessions and the Medicare additional-hour codes.
How Does Dietitian Billing Work?
Dietitian billing works by reporting MNT in 15-minute units for individual visits (97802, 97803) or 30-minute units for groups (97804), under a covered diagnosis and a valid referral, within the payer's hour limit. Qualigenix checks the referral and diagnosis before the first visit, tracks the hours each patient has used, and codes every visit at 98.9% coding accuracy. Call 786-259-0231 to talk through your practice.
01
Timed MNT Unit Coding
97802 and 97803 are billed per 15 minutes of face-to-face time with the patient, and 97804 per 30 minutes of group time. Units billed without the minutes in the note, or rounded past what the note supports, don't hold up on review.
02
Referral & Order Requirements
Medicare covers MNT only on a referral from the treating physician, and follow-up hours need a new referral each calendar year. Commercial plans may require a referral, an order or prior authorization, depending on the plan.
03
Medicare Hour Limits
Medicare covers 3 hours of MNT in the first calendar year and 2 hours in each later year. Extra hours need a second referral for a change in diagnosis, medical condition or treatment, and they're billed with G0270 or G0271.
04
Telehealth Nutrition Visits
Medicare added individual MNT codes to its telehealth services list, and commercial plans set their own telehealth rules. Each telehealth claim needs the right place-of-service code and any modifier the payer requires.
05
Covered-Diagnosis Checks
Medicare covers MNT for diabetes, kidney disease not on dialysis, and a kidney transplant in the last 36 months. A patient on maintenance dialysis isn't covered under the MNT benefit, and obesity alone falls outside it.
06
Assessment & Progress Notes
Each MNT note needs the face-to-face time, the nutrition assessment or reassessment, the intervention and the plan. Without the minutes, the units on the claim can't be supported.
07
Diagnosis & Frequency Denials
Payers deny MNT when the diagnosis on the claim isn't on their covered list, when hours pass the annual limit, or when MNT and diabetes self-management training (DSMT) are billed for the same day.
08
RD Enrollment & Payer Rules
A registered dietitian has to be enrolled in Medicare and credentialed with each commercial plan to bill under their own NPI. A claim from an RD who isn't enrolled is denied however well the visit was documented.
How Qualigenix Closes Each MNT Billing Gap
Qualigenix handles each of these rules as a check that happens before the claim goes out.
Unit & Time Audits
Coders count units from the minutes in the note and bill no more than the documented time supports.
Referral Capture Before Visit One
The referral is collected and checked for the treating physician and a covered diagnosis before the first visit is scheduled, and renewed each calendar year.
Hour Tracking & Second Referrals
We track the hours each Medicare patient has used and request a second referral before the limit is reached, so additional hours bill under G0270 or G0271.
Telehealth Claim Setup
Telehealth visits are billed with the place-of-service code and modifier each payer requires, under that payer's telehealth policy.
Diagnosis & Benefit Verification
Before the first visit, we confirm the diagnosis is covered and check the plan's nutrition benefit, visit limits and any authorization rules.
Note Review Against Payer Rules
Notes are checked for time, assessment, intervention and plan before billing, and the dietitian gets a query when something is missing.
Denial Appeals
Denials are worked by root cause and appealed with the referral, diagnosis and notes attached. Qualigenix overturns 79% of the denials it works, with an average appeal turnaround under 9 days.
Enrollment & Credentialing Checks
Qualigenix's credentialing team handles Medicare enrollment and commercial payer credentialing for dietitians and has completed 12,500+ credentialing applications.
CASE STUDY 01
How a 3-provider podiatry group cleared $214K in aged A/R
THE SITUATION
A 3-provider podiatry group with roughly 60% Medicare payer mix carried $412,000 in A/R, 38% of it past 120 days. Routine foot care claims (11720, 11721, 11055–11057) had stalled on inconsistent Q7/Q8/Q9 modifiers and class-finding documentation, so payers held or partially paid and nobody worked the remainder. Medicare crossover to secondaries was not being posted, and small patient balances were written off.
WHAT QUALIGENIX DID
We ran a full A/R aging segmentation, worked claims by payer and denial reason rather than by date, rebilled the stalled routine-care claims with corrected modifiers, and reactivated secondary and crossover billing.

Audited Practice Results
How a solo podiatrist lifted first-pass acceptance to 96%
THE SITUATION
A solo podiatrist coding 320 encounters a month was stuck at 82% first-pass acceptance. Routine foot care went out without the systemic-condition diagnosis pairing and class findings Medicare requires, so it read as non-covered. Wound debridement was coded to the wrong depth (11042 for skin and subcutaneous where the note supported 11043 for muscle and fascia). Same-day E/M with a procedure went out without modifier 25 and got bundled.
WHAT QUALIGENIX DID
We rebuilt the coding workflow: diagnosis-to-CPT pairing rules for at-risk foot care, correct Q-modifier logic, depth-based debridement coding tied to the operative note, and disciplined use of modifiers 25 and 59/XS.

How a 2-location podiatry practice cut its denial rate by two-thirds
THE SITUATION
A 2-location podiatry practice sat at a 19% denial rate, mostly Medicare routine-foot-care and nail-debridement rejections. The denials clustered in three buckets: medical-necessity rejections on routine foot care (missing qualifying diagnosis and class findings), frequency-edit denials on nail debridement billed inside the 60-day window, and missing Q modifiers that flagged services as non-covered.
WHAT QUALIGENIX DID
We built a front-end denial-prevention layer, checking eligibility and coverage against payer LCDs before claims went out, plus a structured appeal workflow with documentation templates mapped to each denial reason.

Initial MNT Assessment (97802)
97802 reports the initial assessment and intervention, individual and face-to-face, per 15 minutes. It's used once for the start of an episode of care, and later visits move to 97803.
COMPLIANCE
How We Keep MNT Billing Compliant
Qualigenix keeps MNT billing compliant by billing units only from documented minutes and billing Medicare MNT only under a current treating-physician referral and a covered diagnosis. Medicare covers MNT for diabetes, kidney disease not on dialysis, and a kidney transplant in the last 36 months, up to 3 hours in the first year and 2 hours in later years, with more only on a new referral. A patient with both diabetes and kidney disease receives the hours for whichever condition allows more, not both, and MNT and DSMT aren't billed for the same day. We hold a 98.6% compliance and audit pass rate with an over- and undercoding rate under 2%, and all work is HIPAA compliant, with patient data handled under strict security controls.
