Specialty billing
Family Medicine Medical Billing Services
Family medicine billing spans preventive care, chronic disease management and acute visits, which means the coding surface is wide rather than deep. Most revenue leakage comes from under-documented evaluation and management levels and from chronic care management services that are delivered but never billed.

The complexity
Why family medicine is uniquely difficult to bill
Evaluation and management levels driven by medical decision making or total time
Annual wellness visits differ from routine physicals in coverage and documentation
Chronic care management requires documented time and consent before it is billable
Preventive services carry no cost-sharing only when coded as preventive
Transitional care management has strict contact and visit timing requirements
Same-day preventive and problem visits require careful modifier and documentation handling
Coding
Family Medicine procedure codes we work with daily
A representative sample, not an exhaustive list. Coders are assigned by specialty rather than pooled.
| Code | Description |
|---|---|
| 99213 | Office visit, established patient, low medical decision making |
| 99214 | Office visit, established patient, moderate medical decision making |
| G0439 | Annual wellness visit, subsequent |
| 99490 | Chronic care management, first 20 minutes of clinical staff time |
| 99495 | Transitional care management, moderate complexity, 14-day visit |
| 99396 | Preventive medicine visit, established patient, ages 40–64 |
Revenue leakage
Where family medicine practices lose money
These are the denial patterns specific to this specialty — the ones a general-purpose billing service will not be looking for.
E/M level not supported
99214 downcoded to 99213 because the note does not establish moderate medical decision making or document total time.
AWV versus physical confusion
Medicare annual wellness visit billed as a routine physical, which Medicare does not cover, or vice versa.
CCM requirements unmet
Chronic care management denied for missing documented patient consent or insufficient documented clinical staff time.
Preventive coding errors
Preventive services coded as problem visits, incorrectly applying patient cost-sharing and triggering complaints.
TCM timing violations
Transitional care management denied because the required contact within two business days or the face-to-face visit window was missed.
Payer landscape
What family medicine practices need to know about payers
Payer policy drives more family medicine denials than coding does. Knowing the policy before the service is what prevents them.
- Medicare covers the annual wellness visit but not a routine physical exam, a distinction that produces persistent patient billing complaints when handled incorrectly.
- Chronic care management requires documented consent before the first billable service, not retroactively.
- Value-based contracts increasingly tie a portion of reimbursement to quality measure performance rather than volume.
Proof
A family medicine practice we worked with
Austin Family Practice reduces denials by 71%
The practice was running a 28% claim denial rate with payment cycles averaging 52 days. Staff were managing billing alongside patient care, which meant follow-up happened only when someone found time for it — so denials went unworked and revenue was written off by default.
We implemented a structured billing review, assigned certified coders to claim preparation, and established systematic denial management with weekly payer follow-up so no denial sat unaddressed.
Results
- Denial rate reduced from 28% to 8% within three months
- Average payment cycle shortened from 52 days to 18
- Monthly revenue increased 32%
- Staff returned to patient care instead of billing administration

Questions
Family Medicine billing FAQ
Last updated August 20, 2026
Reviewed by a certified coding leadSince the 2021 guideline revision, office visit levels are selected by either medical decision making or total time on the date of the encounter — history and exam no longer drive level selection. Most practices under-bill because they document thoroughly but never record total time, losing the alternative pathway to a higher supportable level.
Medicare covers the annual wellness visit, a structured preventive service with specific required elements, but does not cover a routine comprehensive physical. Billing one as the other either produces a denial or leaves the patient with an unexpected bill. They are different services with different documentation requirements.
CCM requires documented patient consent obtained before the first billable service, a qualifying condition set, and at least 20 minutes of clinical staff time per calendar month directed by the physician. The time must be documented contemporaneously. Practices deliver this care routinely and bill it rarely.
Because preventive services carry no patient cost-sharing only when coded as preventive. When a preventive visit is coded as a problem visit — or when a problem addressed during a physical is not split out correctly — the patient receives a bill they were told they would not get.
