What G2001 covers
G2001 represents a home-based visit for a new patient following discharge. The clinician evaluates the patient’s status and needs in the home setting. The post-discharge context, home location, new-patient status, and 20-minute service level distinguish this code from other entries in the G2001-G2009 series.
Choose G2001 when the documented visit matches the new-patient category and 20-minute level. The neighboring codes identify longer time levels or visits for established patients. Record the discharge-related purpose, where the service occurred, the patient’s status, and the time supporting the selected level. CMS assigns physician fee schedule values for physician work, practice expense, and malpractice.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

G2001 billing questions
How does G2001 differ from G2002?
Both identify post-discharge home visits for new patients. G2001 is the 20-minute level; G2002 is the 30-minute level.
How does G2001 differ from G2006?
G2001 is for a new patient, while G2006 identifies the 20-minute post-discharge home visit level for an established patient.
What should the note support?
Document the relationship to the discharge, the home setting, new-patient status, and the time level reported.
Does the code describe a clinic visit?
No. G2001 identifies a post-discharge home visit, not an office-based follow-up.
When should a longer time-level code be considered?
Use the corresponding longer-duration sibling when the documented post-discharge home visit supports that level, rather than reporting G2001.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
