Infectious Disease Medical Billing Services
Infectious disease billing combines complex consultative E/M visits with IV antibiotic infusion administration, often in inpatient or home-infusion settings. Flint RCM's infectious disease accounts are staffed by coders fluent in this mix.
Specialty-specific pitfalls we watch for.
- High-complexity E/M visits under-coded relative to the documented decision-making involved
- IV antibiotic infusion administration coding errors between initial and sequential drug administration
- Prolonged service codes billed without documentation of the extra time and reason
- Home infusion therapy billing split incorrectly between the physician and infusion provider
- Consultation documentation gaps for inpatient infectious disease consults
- E/M levels checked against the genuinely high complexity typical of infectious disease consults
- Infusion administration hierarchy (initial vs. sequential) coded per documented drug sequence
- Prolonged service billing reviewed against documented time and medical necessity
- Home infusion billing split verified between physician oversight and infusion provider services
What makes Infectious Disease coding different.
- CPT 99202–99255 (E/M, including inpatient consults) leveled against documented complexity, not undercoded by default
- CPT 96365–96379 (IV infusion/injection) coded to the documented drug administration sequence
- Prolonged service add-on codes billed only with documentation of the specific extra time and reason
What to confirm before the visit.
- Home infusion therapy coverage and billing arrangement confirmed before starting outpatient IV antibiotic therapy
- Prior authorization confirmed for extended IV antibiotic courses where required
High-complexity E/M visits are frequently under-coded out of caution — AR follow-up reviews documentation to confirm the visit was billed at the level actually supported.
Our workflow for infectious disease billing.
Documentation Review
Consult and treatment notes are reviewed to confirm complexity and infusion details.
Coding & Level Check
E/M level and infusion administration coding are verified against documentation.
Authorization Confirmation
Coverage for extended IV antibiotic courses is confirmed before treatment continues.
AR Follow-Up
Under-leveled E/M and infusion-coding denials are worked with the consult documentation.
What shapes infectious disease reimbursement.
Payers apply differing definitions of what supports a high-complexity consult E/M level — documentation is reviewed against the specific payer's coverage policy where available.
Infectious Disease billing, answered.
Do you handle home infusion therapy billing?
Yes — billing is split correctly between physician oversight and the infusion provider's services.
How do you ensure complex visits aren't under-coded?
Documentation is reviewed against actual medical decision-making complexity rather than defaulting to a conservative level.
